A strong 18-inch Mickey Thompson tire should match your vehicle’s approved size and the driving you actually do, whether that means street-to-strip traction, a dedicated front fitment, or mixed on- and off-road use. The ET Street S/S P285/40R18 is the leading choice here because it combines a D.O.T.-certified street design with an R2 compound and a size clearly specified for an 18-inch rim. This roundup also includes ET Street R and front-tire options, plus Baja Boss A/T and Baja Legend EXP truck tires.
Their intended uses and sizes differ substantially, so the rankings weigh fit to common street-performance needs alongside the listed specifications. Confirm your vehicle’s required tire size, load rating, and wheel fitment before choosing; an 18-inch rim alone does not establish compatibility.
The Mickey Thompson ET Street S/S 285/40R18 is the best overall pick in this group for a street-and-strip buyer: it is sized for an 18-inch rim, D.O.T.-certified for street use, and uses the R2 compound for strip traction. Its redistributed tread void is listed as improving tread contact and dry traction. Choose it only if 285/40R18 matches your vehicle and wheel requirements; the other listings include different widths, front-only designs, and all-terrain truck tires.

Detailed Reviews: Best 18 Inch Mickey Thompson Tires

#1 · Best Overall
1. Mickey Thompson ET Street S/S 285/40R18
- Size: P285/40R18
- Rim Size: 18 in
- Weight: 29 lb
- Load Capacity: 1565 lb
Best for: Street-to-strip drag radial.
Why it ranks #1: Its 285/40R18 size fits an 18-inch rim, while the R2 compound, redistributed tread void, and D.O.T. certification suit street-to-strip use.
The ET Street S/S pairs a proven R2 compound with a redistributed tread void, giving the P285/40R18 a street-legal route to improved strip traction and dry-road contact. Its D.O.T. certification makes it a relevant option for drivers who want one tire serving street use and drag-strip outings.
The R2 compound is specified to improve strip traction with little to no burnout required, which can simplify preparation before a pass. A redistributed tread void increases tread contact for excellent dry traction, while tubeless construction provides a leak-free seal without tubes. The 285/40R18 size and 18-inch rim specification define its fitment; wheels are sold separately, so plan for a compatible wheel rather than a complete wheel-and-tire package.
- Proven R2 compound for strip traction
- Little to no burnout required, according to the listing
- Redistributed tread void for improved dry traction
- Tubeless construction and D.O.T. street certification
- Wheels are sold separately, so this is not a complete wheel-and-tire package.
Skip it if you need a tire specifically identified as a race tire; the Mickey Thompson ET Street R P305/45R18 is described that way.
For drivers seeking a D.O.T.-certified street tire for dry-road use and drag-strip traction, this 285/40R18 S/S is a focused choice. Its size and separate-wheel listing make fitment and wheel sourcing key considerations.

#2 · Wider Profile Option
2. Mickey Thompson ET Street S/S 275/45R18
- Size: P275/45R18
- Rim Size: 18 in
- Weight: 32.1 lb
- Load Capacity: 1700 lb
Best for: Street-and-strip radial choice.
Why it ranks #2: This 275/45R18 street/drag-strip tire pairs an 18-inch rim fitment with radial construction and the ET Street S/S R2 compound.
The ET Street S/S combines a stated 27.74-inch outer diameter with a 275/45R18 size, giving buyers concrete fitment details for a street-to-strip radial. Its description identifies radial construction and an R2 compound, positioning it for drivers who want a street tire that can also be driven on the track.
The 275/45R18 size and 18-inch rim specification help narrow fitment, while the listed 10.83-inch tire width and 27.74-inch outer diameter offer further dimensions for planning. The product description identifies radial construction and an R2 compound, linking this tire to the ET Street S/S street-to-strip role. Unlike some entries with detailed tread claims, this listing does not specify D.O.T. certification or tubeless construction, so rely on the stated facts when comparing options.
- 275/45R18 size for an 18-inch rim
- 27.74-inch stated outer diameter
- Radial construction identified in the description
- Street-to-strip use stated in the description
- The listing does not specify D.O.T. certification or tubeless construction.
Skip it if you require explicitly listed D.O.T. certification; the Mickey Thompson ET Street S/S P285/40R18 states that certification.
Consider this ET Street S/S if the listed 275/45R18 dimensions suit your vehicle and you want a radial described for street and track driving. Its feature details are less extensive, so prioritize only the claims supplied here.

#3 · Minimal Tread Void
3. Mickey Thompson ET Street R 305/45R18
- Size: P305/45R18
- Rim Size: 18 in
- Weight: 32 lb
- Load Capacity: 2337 lb
Best for: Street-legal race-tire use.
Why it ranks #3: The 305/45R18 ET Street R is D.O.T.-certified for street use and uses minimal tread void to promote tread contact for strip-focused driving.
The ET Street R is identified as a race tire that can be driven on the street, combining a D.O.T.-certified designation with a 305/45R18 size. Its R2 compound targets improved strip traction with little to no burnout required, making this model relevant to drivers focused on race-oriented use.
A minimal tread void promotes excellent tread contact, a feature tied in the listing to its strip-focused role. The R2 compound is specified to improve strip traction with little to no burnout required, while tubeless construction provides a leak-free seal without tubes. Its 305/45R18 size and 18-inch rim specification define the stated fitment; wheels are sold separately, so a tire purchase does not complete the wheel setup.
- R2 compound targets improved strip traction
- Little to no burnout required, per the listing
- Minimal tread void promotes tread contact
- Tubeless construction and D.O.T. street certification
- Wheels are sold separately, leaving wheel selection to the buyer.
Skip it if you want the ET Street S/S street-to-strip radial rather than a tire described as race-oriented; consider the Mickey Thompson ET Street S/S P285/40R18.
This ET Street R suits drivers seeking a D.O.T.-certified tire described for race use that can also be driven on the street. Its 305/45R18 fitment and separately sold wheels are important boundaries to plan around.

#4 · Extra-Wide Fitment
4. Mickey Thompson ET Street S/S 345/35R18
- Size: P345/35R18
- Rim Size: 18 in
- Weight: 38 lb
- Load Capacity: 176 lb
Best for: Wide street-strip fitment.
Why it ranks #4: Its listed 345/35R18 size offers a notably wide option, with the R2 compound and D.O.T.-certified street-use design for strip traction.
With a P345/35R18 size, this ET Street S/S brings Mickey Thompson’s street-to-strip radial format to a particularly wide 18-inch fitment. Its R2 compound targets improved traction at the strip, while D.O.T. certification supports street use for drivers seeking a single tire for both settings.
The R2 compound is specified to improve strip traction with little to no burnout required, reducing the stated need for a lengthy burnout before a pass. A redistributed tread void promotes greater tread contact and excellent dry traction, while tubeless construction provides a leak-free seal without tubes. The 345/35R18 size defines the fitment, and the listing says wheels and tires are sold separately, so the tire alone does not supply a wheel.
- P345/35R18 size for an 18-inch rim
- R2 compound targets improved strip traction
- Little to no burnout required, per the listing
- Tubeless construction and D.O.T. street certification
- Wheels are sold separately, so a wheel must be sourced independently.
Skip it if you want a tire explicitly categorized as a race tire; the Mickey Thompson ET Street R P305/45R18 is listed as one.
This S/S suits drivers whose vehicle calls for the listed 345/35R18 size and who want street certification alongside strip-focused traction features. Check that exact fitment and arrange a separate wheel; the listing does not include one.

- Rim Size: 18 in
- Weight: 25 lb
- Load Capacity: 1650 lb
Best for: Street-rod staggered front fitment.
Why it ranks #5: The 28X6.00R18LT radial is designed for street rods and muscle cars, with a flamed tread pattern and matching front and rear patterns.
The Sportsman S/R uses matching front and rear tread patterns for staggered fitments, a practical detail for street rods and muscle cars seeking coordinated tire styling. This 28X6.00R18LT front tire also combines a flamed tread pattern with radial construction, which the listing associates with wet traction and a smooth ride.
The matching front-and-rear tread patterns support a coordinated appearance when a vehicle uses staggered fitments, while custom sizes are identified for street rods and muscle cars. Its flamed tread pattern is specified to improve wet traction, and radial construction is linked to a smooth ride and long mileage. The 28X6.00R18LT size and 18-inch rim specification establish the listed fitment; wheels are sold separately, so the tire is not a wheel package.
- Matching front and rear tread patterns for staggered fitments

The Sportsman S/R suits street-rod or muscle-car owners who need the listed 28X6.00R18LT front size and matching tread patterns for staggered fitments. It is a specific street-oriented fitment, with wheels sourced separately.

- Size: 28X6.00R18LT

Why it ranks #6: This 18-inch ET Street Front weighs 18 pounds and is designed to pair with ET Street R, S/S, and Radial Pro rear tires.
At a listed 18 pounds, the ET Street Front is a lightweight 28X6.00R18LT option for drag-car front fitments. Its radial construction is specified to lower rolling resistance, and the product is described as a pairing for Mickey Thompson ET Street R, S/S, and Radial Pro lines.
The 28X6.00R18LT size and 18-inch rim specification identify its intended dimensional category, while the lightweight construction is presented as a way to unlock quicker elapsed times. Radial construction is specified for lower rolling resistance, connecting its build to reduced resistance as the car rolls. D.O.T. certification supports street use, and the listing names ET Street R, S/S, and Radial Pro tires as compatible pairing lines; wheels are sold separately.
- Lightweight construction aimed at quicker elapsed times
- Radial construction for lower rolling resistance
- D.O.T. certified for street use
- Listed as a pairing for ET Street R, S/S, and Radial Pro
- This is an ET Street Front tire, not a general-purpose all-terrain tire.

Choose this front tire when a 28X6.00R18LT fitment and a pairing with an ET Street drag-radial line suit your setup. Its listed role is specific: it is a front tire, not a broad-use truck option.

- Load Capacity: 2756 lb
Best for: Snow-rated mixed-terrain truck.
Why it ranks #7: The 265/65R18 all-terrain has a 3PMSF designation, an asymmetric tread, and a listed 60,000-mile limited treadwear warranty.
The Baja Boss A/T in 265/65R18 carries a Three-Peak Mountain Snowflake designation, giving buyers a specific all-terrain option for qualifying winter-condition use. Its asymmetric tread is optimized for off-road traction, on-road handling, and reduced noise, while the S1 compound targets wet handling and cold-weather traction.
The asymmetric tread pattern balances stated priorities of reduced noise, off-road traction, and on-road handling, making it suited to drivers who divide time between pavement and trails. The S1 compound is specified for wet handling and braking, lasting treadlife, and cold or wet weather traction. Its 3PMS designation applies to sizes 12.50 inches and narrower, including this 265/65R18 listing; the 60,000-mile limited treadwear warranty is another ownership detail.

- Rim Size: 18 in
- Weight: 44 lb
- Load Capacity: 2601 lb
Best for: Baja Boss A/T 265/60R18.
Why it ranks #8: This 265/60R18 Baja Boss A/T offers the same listed 3PMSF designation and 60,000-mile limited treadwear warranty in a different size.
This Baja Boss A/T uses a 265/60R18 fitment and an asymmetric tread optimized for reduced noise, off-road traction, and on-road handling. Its S1 compound targets wet handling and braking as well as cold-weather traction, while the Three-Peak Mountain Snowflake designation adds a specific winter-use credential.
The asymmetric tread connects mixed-terrain capability with stated on-road handling and reduced noise, a useful combination for drivers moving between pavement and off-road surfaces. The S1 compound is specified to support wet handling and braking, lasting treadlife, and cold or wet weather traction. This version’s 265/60R18 size distinguishes its fitment; its 3PMS designation applies to sizes 12.50 inches and narrower. A 60,000-mile limited treadwear warranty is also listed.
- Asymmetric tread optimized for off-road traction
- Tread design also targets on-road handling and reduced noise
- S1 compound specified for wet and cold-weather traction
- Three-Peak Mountain Snowflake designation
- The listing specifies 265/60R18, so it does not serve vehicles requiring another tire size.
Skip it if you need the Baja Boss A/T in 265/65R18; the Mickey Thompson Baja Boss A/T 265/65R18 is listed in that size.
This version suits truck owners seeking Baja Boss A/T features in the specific 265/60R18 size, including a snow designation and wet-weather compound claims. Confirm that this listed size matches the intended vehicle fitment.

View on AmazonWhy an 18-inch rim does not guarantee a fit
An 18-inch rim does not make these tires interchangeable: the listed sizes span different widths, aspect ratios, and tire types. For example, the ET Street S/S options include 275/45R18, 285/40R18, and 345/35R18, while the Baja Boss A/T choices are 265/60R18 and 265/65R18. The front-focused 28X6.00R18LT products are another distinct format, not a direct substitute for a wide rear drag radial.
A mismatch can create clearance or handling problems, and a tire that mounts to a wheel may still be unsuitable for the vehicle. Compare the complete size printed on your current tire with the vehicle placard or owner information, and verify load and wheel requirements before buying.
Do not choose by rim diameter alone. These listings provide tire dimensions and some load data, but do not identify vehicle-specific fitment.
Front tires and rear drag radials serve different roles
A front tire designed to complement a drag-radial setup is not a substitute for the rear tire, and the product descriptions make that distinction explicit. The ET Street Front is described as a pairing for ET Street R, S/S, and Radial Pro lines; the Sportsman S/R instead emphasizes matching front and rear tread patterns for staggered fitments. Those specialized choices can make sense for a street rod or a purpose-built performance setup, but they are less suitable as a general-purpose replacement choice.
Also, the street-and-strip models emphasize dry traction and tread contact, while the Baja Boss A/T and Baja Legend EXP are described for mixed on- and off-road use. Using a tire outside its intended role may leave you with the wrong dimensions or performance priorities.
Check axle position, existing tire sizes, and the vehicle maker’s requirements before mixing designs or selecting a front-only option.
How to Choose an 18-Inch Mickey Thompson Tire
Match the complete tire size
Start with the complete tire size, not just the 18-inch rim diameter. The street-and-strip choices range from 275/45R18 and 285/40R18 to 345/35R18; truck-oriented examples include 265/60R18, 265/65R18, LT275/65R18, and LT265/70R18. The 28X6.00R18LT front tires use a different sizing format.
These dimensions are not interchangeable simply because they share an 18-inch rim. A buyer replacing a fitted performance tire should focus on the original size and vehicle guidance; a truck owner should compare the listed LT or metric size against the vehicle’s approved fitment.
Confirm clearance and wheel compatibility with a qualified tire professional when moving away from the current specification.
Choose a tire for its driving role
Choose among these listings according to whether you need street-to-strip, front-axle, or all-terrain use. The ET Street S/S and ET Street R are D.O.T.-certified street-use tires described with features focused on drag-strip traction and tread contact. The ET Street Front is explicitly intended to pair with drag-radial lines, while the Sportsman S/R is aimed at street rods and muscle cars.
For mixed road and trail use, the Baja Boss A/T lists an asymmetric tread and 3PMSF designation, and Baja Legend EXP is described as a hybrid all-terrain tire. A performance-car owner prioritizing strip traction should look first at the ET Street options; a truck buyer seeking a listed all-terrain design should compare the Baja models instead.
Check load data and warranty details
Compare the listed load capacity and warranty information against your vehicle’s requirements; neither should be inferred from tire size alone. The data range from 1,140 pounds for the ET Street Front 28X6.00R18LT to 3,525 pounds for the Baja Legend EXP LT265/70R18. Other examples include 1,565 pounds for the ET Street S/S 285/40R18 and 2,756 pounds for the Baja Boss A/T 265/65R18.
Warranty listings also vary: the Baja Boss A/T lists a 60,000-mile limited treadwear warranty, and Baja Legend EXP lists 50,000 miles. A truck owner should verify the required load rating and tire position; a performance-car buyer should not assume that a higher listed capacity makes a tire the right size or use case.
Which 18-inch Mickey Thompson tire should you choose?
For a street-and-strip setup in the listed size, choose the Mickey Thompson ET Street S/S 285/40R18: it combines the R2 compound, dry-traction tread design, and D.O.T. street-use certification. If your vehicle requires 275/45R18, consider the Mickey Thompson ET Street S/S 275/45R18; for the listed 305/45R18 size and a more strip-focused tread, consider the Mickey Thompson ET Street R 305/45R18.
Street-rod buyers should compare the Mickey Thompson Sportsman S/R 28X6.00R18LT with the front-only Mickey Thompson ET Street Front 28X6.00R18LT, which is intended to pair with drag-radial lines. Truck buyers should look to the Baja Boss A/T or Baja Legend EXP, choosing only the size and load data that match their vehicle.
Verify fitment before ordering.
Frequently Asked Questions
How do I verify that an 18-inch tire size fits my vehicle and wheels?
Check your vehicle placard or owner’s manual for approved tire sizes, then confirm the wheel diameter and width requirements in your wheel documentation. Compare the complete tire size and load rating with your vehicle’s requirements. If anything differs or is unclear, ask a qualified tire professional to verify fitment before ordering.
Can a D.O.T.-certified drag radial be used as an everyday tire?
A D.O.T.-certified drag radial may be intended for street use, but certification alone does not establish that it suits every daily-driving need. Consider the manufacturer’s use guidance and your vehicle’s requirements, and check conditions such as weather and road use. The listed ET Street S/S is identified as D.O.T.-certified for street use.
Should I replace tires in pairs or match all four tires on my vehicle?
Follow your vehicle manufacturer’s replacement guidance, since the right choice depends on the vehicle and its drivetrain. Matching tires across an axle—and, where required, across all four positions—can help maintain consistent fit and handling. Check size, load requirements, and tire condition, and consult a tire professional if you are unsure.
How do the listed ET Street S/S and ET Street R differ?
The ET Street S/S is the listed choice for a street-and-strip setup, while the ET Street R is presented as having a more strip-focused tread. The editorial pick is the S/S 285/40R18 for a matching fitment; the R listing is 305/45R18. Confirm your vehicle and wheel requirements before choosing either.
What should truck buyers check when choosing among the Baja listings?
Match the exact tire size and load data to your truck’s requirements rather than choosing by model name alone. The listings include Baja Boss A/T and Baja Legend EXP options in different sizes and load designations. Verify fitment against your vehicle documentation and consult a tire professional if the required data is uncertain.
Final Words
For a street-and-strip setup that requires 285/40R18, choose the ET Street S/S: its listed R2 compound, dry-traction tread design, and D.O.T. street-use certification align with that role. If your required size differs, compare the alternate S/S or the more strip-focused ET Street R instead.
Street-rod and truck buyers should stay with the listings suited to those uses, and verify size, wheel, and load requirements before ordering.
