A strong 7.5L-15 tractor tire should match your tractor’s required size and role, with a suitable tread and load rating for the work you do. The Forerunner QH621 7.5L-15 is a practical starting point for shoppers seeking an exact-size, 8-ply bias tire with a listed 1,653-pound load capacity. This roundup also includes 6-ply tractor tires, three-rib front and implement designs, and nearby 7.6-15 or 7.60-15 sizes.
Those distinctions matter: a tire described for implement use may not be the right replacement for a tractor’s front axle, and similar size labels do not by themselves confirm fit. Check your equipment’s specified tire size, rim, load requirement, and intended position before choosing.
Every listing here is tire-only or does not clearly include a wheel.
The Forerunner QH621 7.5L-15 is the leading all-around pick because it matches the requested 7.5L-15 size, uses 8-ply bias construction, and lists a 1,653-pound load capacity. It is identified as a tire only, so you will need to confirm that your existing 15-inch rim and tractor requirements match. For a dedicated three-rib front tire or an implement tire, compare the specialized Firestone and SUPERGUIDER options below.

#1 · Best Overall
1. Forerunner QH621
- Size: 7.5L-15
- Weight: 27 lb
- Load Capacity: 1653 lb
- Rim Size: 15 in
Best for: Single-Tire Tractor Replacement.
Why it ranks #1: Its 7.5L-15 size directly matches the search, while 8-ply bias construction and a listed 1,653-pound load capacity suit tractor replacement consideration.
An 8-ply bias construction paired with a 1,653-pound load capacity makes the Forerunner QH621 a practical single-tire replacement for a tractor using a 7.5L-15 tire. Its 15-inch rim size gives buyers a specific sizing reference, while the listed tire-only contents clarify what arrives for installation.
The 8-ply rating and stated 1,653-pound load capacity give buyers useful construction and load figures to compare with their tractor’s requirements. Its 7.5L-15 size and 15-inch rim size help narrow the fit check before arranging installation. The product includes the tire only, so the purchase covers a replacement tire rather than a wheel-and-tire assembly. At 27 pounds, its listed weight also helps with handling and planning the installation workflow.
- 8-ply bias construction
- 1,653-pound stated load capacity
- 7.5L-15 size
- 15-inch rim size
- Tire only; no rim is included.
Skip it if you need a rim-and-tire assembly in one purchase; this listing includes the tire only.
This suits tractor owners replacing one 7.5L-15 tire who want an 8-ply option and a stated 1,653-pound capacity. It is a tire-only purchase, so account for the wheel separately when planning installation.

2. Firestone Regency 3-Rib Plus
- Size: 7.5L-15
- Weight: 27 lb
- Load Capacity: 1433 lb
- Rim Size: 15 in
Best for: Soft and Uneven Ground.
Why it ranks #2: This exact-size 7.5L-15 tire is specifically described as a tractor front tire, with a ribbed tread and a 1,433-pound capacity.
A ribbed tread and rubber compound are the Firestone Regency AG 3-Rib Plus’s stated approach to soft, loose, and uneven surfaces. For tractor front-tire replacement, its 7.5L-15 size and 15-inch rim specification provide sizing details, while the listed capacity is 1,433 pounds.
Firestone states that the ribbed tread and rubber compound improve performance on soft, loose, and uneven surfaces, making the tire’s terrain focus clear. The optimized tread is also described as keeping the footprint clean during operation, a feature relevant to maintaining contact as work continues. Its 7.5L-15 size and 15-inch rim size help guide fit planning, and the 1,433-pound load capacity is a specific limit to compare with the tractor’s front-axle needs.
- Ribbed tread pattern
- Specified for soft, loose, and uneven surfaces
- Optimized tread keeps footprint clean
- 1,433-pound stated load capacity
- The listed load capacity is 1,433 pounds.
Skip it if you need a tire with a stated capacity above 1,433 pounds; this listing provides no higher figure.
This fits tractor owners seeking a front bias tire for soft, loose, or uneven ground, with the tread features described for those surfaces. Check the 1,433-pound capacity and 7.5L-15 size against the intended position.

#3 · All-Season Tractor
3. Agstar 3340
- Size: 7.5L-15
- Weight: 34 lb
- Rim Size: 15 in
Best for: All-Season Agricultural Tractor.
Why it ranks #3: The 7.5L-15 Agstar is a 6-ply tractor tire with bias construction and an all-season description, though no load capacity is listed.
Agstar’s 3340 combines a 7.5L-15 size with a 6-ply rating and all-season tractor use, giving buyers a direct set of replacement specifications. Its tread design is described as improving steering responsiveness and stability through constant surface contact, with soft-terrain traction also noted.
The tread design’s constant surface contact is linked in the supplied description to steering responsiveness and driving stability, helping explain its relevance to tractor control. The same description notes soft-terrain traction, so the stated benefits extend to the listed terrain use. Its 6-ply rating, bias construction, and 15-inch tire specification help buyers compare it with their setup. The listing includes the tire only and explicitly excludes the rim or wheel, which matters for installation planning.
- 6-ply rated construction
- All-season tractor use
- Tread design supports steering response and stability
- Soft-terrain traction noted
- The rim and wheel are not included.
Skip it if you need a complete wheel-and-tire assembly; this listing specifies a tire only and excludes the rim or wheel.
Choose this for agricultural tractor use when the all-season designation, 6-ply rating, and stated soft-terrain traction suit the job. It arrives without a rim or wheel, so plan installation around a separate wheel.

4. Carlisle Farm Specialist
- Size: 7.5L-15
- Weight: 27 lb
- Rim Size: 7.5 in
Best for: Six-Ply Farm Replacement.
Why it ranks #4: It is an exact 7.5L-15 tractor tire with a listed 6-ply rating; verify the stated 7.5-inch rim size against your equipment.
Carlisle’s Farm Specialist pairs a 7.5L-15 tractor size with a 6-ply load range, giving buyers a clearly specified replacement option for an all-season tractor application. Its listed 7.5-inch rim size is an important fit detail to review alongside the tire size before installation.
The 6-ply rating identifies the construction level for buyers matching a replacement to their tractor’s needs, while the all-season designation supports use across the stated seasonal category. The 7.5L-15 size is paired in the listing with a 7.5-inch rim size, so checking both dimensions is important when planning fit and installation. Carlisle identifies this as a tractor tire; the supplied details do not specify a load capacity or performance rating beyond the stated features.
- 7.5L-15 tire size
- 6-ply load range
- All-season designation
- Identified for tractor use
- The supplied specifications do not state a load capacity.
Skip it if you need a stated load-capacity figure before choosing; this listing does not provide one.
This is for tractor owners seeking an all-season 7.5L-15 tire with a 6-ply rating. Review the listed 7.5-inch rim size carefully during fit planning, and note that the supplied specifications leave load capacity unstated.

5. Forerunner QH621 Two-Tire
- Size: 7.5L-15
- Weight: 54 lb
- Load Capacity: 1653 lb
- Rim Size: 15 in
Best for: Two-Tire Tractor Replacement.
Why it ranks #5: This listing identifies two exact-size 7.5L-15 QH621 tires and 8-ply bias construction, with a listed 1,653-pound load capacity.
This Forerunner QH621 listing specifies two 7.5L-15, 8-ply bias tires, making it the set option among the listed QH621 products. Each tire has a stated 1,653-pound load capacity and 15-inch rim size, giving buyers paired replacement quantities and fit details.
The two-tire quantity can support a paired replacement workflow rather than sourcing each tire separately, while the 8-ply bias rating describes the listed construction. Forerunner states a 1,653-pound load capacity and a 15-inch rim size, useful figures to compare with the tractor’s requirements and wheel setup. The 7.5L-15 size identifies the tire specification. The listing includes tires only, so it does not provide wheels or a complete wheel-and-tire assembly.
- Two tires listed
- 8-ply bias construction
- 1,653-pound stated load capacity
- 7.5L-15 size with 15-inch rim specification
- The listing includes tires only, not wheels.
Skip it if you need wheels included with your replacement tires; this listing supplies tires only.
This suits tractor owners replacing a pair of 7.5L-15 tires who want the stated 8-ply construction and capacity. Confirm that the paired quantity fits the job, and plan to use separate wheels for installation.

#6 · Tubeless Implement
6. SUPERGUIDER F-2 Rib Implement
- Size: 7.5L-15
- Weight: 28.6 lb
- Load Capacity: 1652 lb
- Rim Size: 15 in
Best for: Tubeless F-2 Implement Tire.
Why it ranks #6: Its 7.5L-15 size, 8-ply rating, and tubeless F-2 three-rib design suit implement use; the listing gives a 1,652-pound capacity.
A tubeless three-rib F-2 pattern defines the SUPERGUIDER Heavy Duty implement tire, with an 8-ply rating and 1,652-pound stated capacity. Its listed resistance to impacts, cuts, and lacerations gives buyers additional field-exposure details to weigh alongside the tire’s load and size specifications.
The three-rib F-2 implement pattern identifies the tire’s intended format, while tubeless construction is a practical specification for buyers matching an existing setup. SUPERGUIDER also states minimal soil embossing and excellent load distribution, connecting the tread design to soil contact and carrying load. The listed resistance to impacts, cuts, and lacerations addresses field exposure. Its 7.5L-15 size, 15-inch rim size, and 1,652-pound capacity help guide fit and load checks.
- Three-rib F-2 implement pattern
- Tubeless construction
- 8-ply rating
- Listed resistance to impacts, cuts, and lacerations
- The stated load capacity is 1,652 pounds.
Skip it if you require a stated load capacity above 1,652 pounds; this listing provides no higher figure.
This suits implement users seeking a tubeless F-2 tire with an 8-ply rating and stated resistance to common forms of field damage. Check the 1,652-pound capacity and 7.5L-15 sizing against the equipment.

7. SUPERGUIDER F-2 Two-Tire
- Size: 7.5L-15
- Weight: 54 lb
- Load Capacity: 1652 lb
- Rim Size: 15 in
Best for: Three-Rib Implement Work.
Why it ranks #7: This two-tire listing offers 7.5L-15, 8-ply tubeless F-2 implement tires with a listed 1,652-pound capacity, rather than a general tractor tread.
A tubeless, three-rib F-2 tread gives the SUPERGUIDER HD a clear implement-tire focus, with a listed 1,652-pound load capacity. The stated minimal soil embossing and load distribution address field contact, while its 8-ply rating provides a concrete construction specification for buyers comparing replacement options.
The three-rib F-2 pattern and tubeless construction identify this as an implement tire rather than a general-purpose wheel assembly, helping buyers match it to the intended tractor setup. SUPERGUIDER lists minimal soil embossing and excellent load distribution, features tied to how the tire meets soil and carries load. Its stated resistance to impacts, cuts, and lacerations speaks to field exposure, while the 15-inch rim size and 7.5L-15 sizing help guide fit checks.
- Three-rib F-2 implement pattern
- Tubeless construction
- 8-ply rating
- Listed 1,652-pound load capacity
- The listing gives a 1,652-pound load capacity, which may not meet higher-load requirements.
Skip it if you need a tire with a listed capacity above 1,652 pounds; the specifications do not state a higher limit.
Choose this for implement work where a tubeless three-rib F-2 pattern and its stated soil and impact characteristics suit the job. Its 1,652-pound load figure remains a boundary to check against the tractor’s requirements.

8. Firestone Regency Rib Implement
- Size: 7.6-15
- Weight: 28 lb
- Load Capacity: 2094 lb
- Rim Size: 15 in
Best for: Eight-Ply Rib Implement Work.
Why it ranks #8: The 7.6-15 implement tire lists 8-ply construction and a 2,094-pound capacity, but its size differs from the requested 7.5L-15.
Firestone’s Regency AG Rib Implement Plus combines an 8-ply bias construction with a listed 2,094-pound load capacity, a useful pairing for buyers evaluating implement work. Its tread pattern and rubber compound are described as improving grip, steering responsiveness, and driving stability.
Firestone ties the tread pattern and rubber compound to stronger grip on the driving surface, alongside improved steering responsiveness and driving stability. Those described handling benefits give the rib implement design practical relevance for tractor work. The 8-ply bias construction and 2,094-pound stated capacity provide specific construction and load details for comparison. Its 7.6-15 size and 15-inch rim specification help with replacement planning, while the tire-only contents mean the wheel is a separate installation consideration.
- 8-ply bias construction
- 2,094-pound stated load capacity
- Rib implement tread
- Tread and compound support grip and stability
- The tire-only listing does not include a wheel.
Skip it if you need a wheel included for installation; this listing supplies the tire only.
This is a fit for tractor owners seeking an 8-ply rib implement tire with the stated 2,094-pound capacity and grip-related benefits. Check the 7.6-15 sizing and arrange the wheel separately before installation.

9. Firestone Regency Traction Implement
- Size: 7.6-15
- Weight: 25 lb
- Load Capacity: 1764 lb
- Rim Size: 15 in
Best for: Responsive All-Season Tractor Use.
Why it ranks #9: This 7.6-15, 6-ply bias tire is described for tractor implement use and lists a 1,764-pound capacity, but it is not the exact size.
Firestone’s Regency AG Traction Implement Plus uses a tread pattern and durable rubber compound to maintain surface contact, supporting steering responsiveness and driving stability. The 7.6-15 size and stated 1,764-pound load capacity give tractor owners practical figures to check against their application.
The supplied description links the tread pattern and durable rubber compound to continuous surface contact, which supports the stated steering responsiveness and driving stability. That combination is relevant to tractor operators seeking controlled handling through all-season use. The 7.6-15 size and 15-inch rim specification help with replacement fit planning, while the listed 1,764-pound capacity provides a load figure to compare with equipment needs. It is supplied as a tire only, not a wheel assembly.
- Tread pattern supports surface contact
- Durable rubber compound
- 1,764-pound stated load capacity
- 15-inch rim size
- The listed load capacity is 1,764 pounds.
Skip it if you require a stated capacity above 1,764 pounds; the supplied specifications do not give a higher limit.
This suits tractor operators looking for the stated all-season traction implement design and its contact-focused handling benefits. Check the 7.6-15 size and 1,764-pound capacity against your equipment, and plan separately for the wheel.

10. Harvest King Rib Implement
- Size: 76015
- Weight: 25 lb
- Load Capacity: 2090 lb
- Rim Size: 15 in
Best for: Higher-Capacity Implement Tire.
Why it ranks #10: It lists a 2,090-pound capacity and 15-inch rim, but its 7.60-15 size and implement designation make it a less direct match.
A listed 2,090-pound load capacity is the defining figure for Harvest King’s Rib Implement tire, which also carries a D/8PR designation. Its 7.60-15 size and 15-inch rim size offer concrete dimensions for buyers replacing an implement tire and planning installation.
The rib implement description and D/8PR marking identify the tire’s stated format and construction rating, giving buyers useful details to compare against their equipment requirements. Harvest King lists a 2,090-pound capacity, which helps assess whether the stated load limit suits the intended work. The 7.60-15 size and 15-inch rim size guide fit checks, while the listing explicitly says the rim is not included, so installation planning must account for the wheel separately.
- 2,090-pound stated load capacity
- D/8PR designation
- Rib implement tire
- 15-inch rim size
- The rim is not included.
Skip it if you need the wheel included with the tire; this listing specifies tire only and no rim.
Consider this for implement work when the 2,090-pound stated capacity and 7.60-15 size suit the equipment. It is not a complete wheel assembly, so have the appropriate rim available for installation.

View on AmazonAvoid the size-label and rim-fit trap
A tire labeled 7.5L-15 is not automatically interchangeable with every listing near that size, so confirm the exact tire specification and rim requirements in your tractor documentation. This selection includes exact 7.5L-15 tires as well as 7.6-15 and 7.60-15 alternatives. Those nearby labels should not be treated as proof of a fit.
The Carlisle Farm Specialist, for example, lists a 7.5-inch rim size even though its product size is 7.5L-15; that is a detail to verify rather than assume. Most of the other listed products specify a 15-inch rim.
Also check the tire’s position: the Firestone Regency 3-Rib Plus is identified as a front tire, while several three-rib products are specifically described as implement tires. Before ordering, compare the sidewall markings on your current tire with the equipment maker’s requirements and check rim diameter, tire position, and load needs.
Match tread purpose to the axle or implement
A three-rib tread label alone does not establish that a tire is intended for the same job as your current tire. The Firestone Regency 3-Rib Plus is explicitly described as a tractor front tire; the SUPERGUIDER F-2 products are described as three-rib implement tires. Firestone and Harvest King also list rib implement tires, while the Firestone Regency Traction Implement is presented as an implement tire with traction in its name.
Choosing by appearance alone can lead to a mismatch in intended position or use. Compare the product description with the role of the tire you are replacing, and confirm suitability with the tractor or implement documentation if it is unclear.
This distinction is especially important when shopping for a front-axle replacement: an implement designation is not the same as a front-tractor designation. The product data provides descriptions and capacities, but it does not establish compatibility with a specific machine.
How to Choose a 7.5L-15 Tractor Tire
Size and rim match
Look for the exact size and rim specification required by your tractor, rather than choosing by a similar label. The listings include 7.5L-15 models, such as the Forerunner QH621 and Agstar 3340, alongside 7.6-15 and 7.60-15 implement tires. Most specify a 15-inch rim, while the Carlisle Farm Specialist lists 7.5 inches, a notable detail to verify.
Buyers replacing an existing tire should prioritize matching the equipment’s specified size and rim; shoppers considering an alternative size should confirm compatibility with the tractor documentation or a qualified tire professional before purchase. A size that looks close in a listing is not a confirmed substitute.
Ply rating and load capacity
Compare the tire’s listed ply rating and load capacity with your equipment’s requirements, since both vary in this selection. The Forerunner QH621 and SUPERGUIDER F-2 are 8-ply options, with capacities listed at 1,653 and 1,652 pounds respectively. The Firestone Regency 3-Rib Plus is 6-ply and lists 1,433 pounds; the 7.6-15 Firestone Regency Rib Implement is 8-ply and lists 2,094 pounds.
Several products do not provide a load capacity in the supplied data. Buyers with a stated load requirement should favor listings with a relevant capacity figure, but should verify that figure against the tractor’s needs rather than assuming higher capacity is automatically the right choice.
Tire role and tread description
Choose a tire described for the position and job you need, not just one that shares the size. The Firestone Regency 3-Rib Plus is identified as a front bias tire for tractors, while the SUPERGUIDER F-2 products are described as three-rib implement tires. Firestone’s Regency Rib Implement and Harvest King’s Rib Implement are also implement-designated; the Firestone Regency Traction Implement is another 7.6-15 option for implement use.
Buyers replacing a tractor front tire should start with a product explicitly described for that role. Those shopping for an implement should compare implement listings and confirm the needed size and capacity.
Where the product description does not specify the intended axle, verify the application before ordering.
Which 7.5L-15 Tractor Tire Should You Choose?
For a general exact-size replacement candidate, start with the Forerunner QH621: it is 7.5L-15, 8-ply, and lists a 1,653-pound capacity. If you specifically need a front tire, the Firestone Regency 3-Rib Plus is the clearest match because its description identifies it as a tractor front tire, though its listed capacity is 1,433 pounds. For an exact-size 6-ply tractor tire, consider the Agstar 3340; the Carlisle Farm Specialist is another 6-ply option, but its listed 7.5-inch rim size deserves careful verification.
For implement use, compare the SUPERGUIDER F-2 Rib Implement or Firestone Regency Rib Implement, checking their size against your machine. Choose the two-tire Forerunner or SUPERGUIDER listing only if you need the listing’s pair quantity.
Frequently Asked Questions
How can I confirm whether a 7.5L-15 tire fits my tractor’s rim and axle?
Check your tractor manual or the existing tire’s markings for the required tire size, rim diameter, and axle position. Confirm those details against the tire listing and verify that its load capacity meets your tractor’s requirements. If the listing is unclear, ask a tire dealer or tractor service professional before ordering.
When should I choose a three-rib front tire instead of an implement tire?
Choose a three-rib front tire when you need a tire specifically identified for the tractor’s front position, and confirm its size and capacity suit your machine. Consider an implement tire when the application calls for that tire type. The Firestone Regency 3-Rib Plus is identified as a front tire; compare implement listings separately.
What should I check before replacing one tractor tire with a different ply rating?
Check the tractor manufacturer’s requirements, the replacement tire’s load capacity, and whether its size and construction suit the axle and application. A different ply rating alone does not confirm compatibility. Compare the new tire’s specifications with the existing tire and machine requirements, and get professional guidance if ratings or fit are uncertain.
Are 7.5L-15 and 7.6-15 tires interchangeable?
Do not assume they are interchangeable based on the markings alone. Compare the complete tire size and rim requirements with your tractor manual and existing tire, and confirm the replacement is approved for the axle and application. The listed 7.6-15 implement options should be checked against your machine before purchase.
How do I tell whether a listing includes one tire or a pair?
Read the full product title and listing details for quantity wording, such as “two tires” or “set 2.” The Forerunner and SUPERGUIDER titles here include pair listings, while other titles do not state a pair in the product name. Confirm the listing quantity before ordering so it matches your replacement need.
Final Words
For a general exact-size replacement, begin with the Forerunner QH621, then confirm its 15-inch rim fit, axle suitability, and load requirements. Choose the Firestone three-rib option when you need a dedicated front tire, or compare the SUPERGUIDER and Firestone implement choices for implement use. If selecting a different ply rating or a 7.6-15 size, verify compatibility carefully; choose pair listings only when you need two tires.
