The best 20-inch Mickey Thompson tire depends on where you drive: the Baja Boss A/T suits mixed road and off-road use, while the Street Comp targets street handling and the ET Street S/S is designed for dry-track traction. For heavier-duty off-road use, compare the Baja Boss A/T E-load option with the Baja Legend MTZ. Check your vehicle’s required tire size and load specifications before choosing.
| Tire | Best For | Key Difference |
|---|---|---|
| Baja Boss A/T 275/60R20 SL | Mixed road and trail driving | All-terrain tread and wet-weather focus |
| Street Comp 255/35R20 XL | Street handling | Cornering and steering response |
| Baja Boss A/T LT275/60R20 E | Off-road use and tougher-duty needs | Sidebiters and reinforced construction |
| Baja Legend MTZ 35X12.50R20LT F | Aggressive mud-terrain style | Three-ply sidewall construction |
| ET Street S/S P305/35R20 SL | Dry drag-strip traction | Track-oriented tread contact |
Baja Boss A/T 275/60R20 SL
Best for: Drivers who split time between paved roads and off-road routes and want an all-terrain design in a 20-inch fitment. It is selected for its combination of on-road handling, off-road traction, and wet-weather features.
The asymmetric tread is designed to reduce noise while supporting off-road traction and on-road handling. Its S1 compound is intended to provide wet handling and braking, treadlife, and cold- and wet-weather traction. The product details also state that the Three-Peak Mountain Snowflake designation applies to sizes 12.50 inches and narrower.
Consider: This is an all-terrain option, not a dedicated mud-terrain or track tire. Confirm the exact size and load rating against your vehicle’s requirements.
Street Comp 255/35R20 XL
Best for: Drivers prioritizing street handling, cornering, and steering response. This tire is selected for its stated high-speed handling focus and wet-and-dry performance rather than off-road capability.
The asymmetric tread is designed for handling and cornering. Product features describe wet and dry traction and an aggressive steering response. Those characteristics make it the more road-focused comparison with the Baja Boss A/T and Baja Legend MTZ.
Consider: The listed features emphasize street performance and do not describe off-road traction or winter designation. Avoid choosing it for trail use based solely on its 20-inch size.
Baja Boss A/T LT275/60R20 E
Best for: Drivers seeking an all-terrain tire with features aimed at demanding off-road use. It shares the Baja Boss A/T’s balance of road handling and trail traction, with added construction and sidewall details that distinguish this LT version.
The asymmetric tread is designed to reduce noise and support off-road traction and on-road handling. Extreme Sidebiters are intended to provide off-road traction and protection. Powerply XD uses heavier-denier cord in the angled third ply; the product description associates it with puncture resistance, steering response, and stability.
Consider: This E-load version is not interchangeable with the SL version just because both are 275/60R20. Check the vehicle’s load requirements and fitment before buying.
Baja Legend MTZ 35X12.50R20LT F
Best for: Drivers who want an aggressive mud-terrain look and a tire described for on- and off-road performance. It stands apart from the all-terrain options with bold MTZ tread styling and a three-ply sidewall construction.
The T4 silica-reinforced compound is described as supporting wet handling and braking, cut-and-chip resistance, and treadlife. PowerPly three-ply sidewall construction is intended to increase puncture resistance and provide more responsive handling.
Consider: The 35X12.50R20LT size and F load designation differ substantially from the other listed options. Verify that your vehicle can use this exact size before selecting it.
ET Street S/S P305/35R20 SL
Best for: Drivers seeking a track-oriented tire for dry traction. It is selected for its R2 compound and tread design focused on contact and traction at the strip, rather than all-weather versatility.
The product description says the R2 compound is designed to improve strip traction with little to no burnout required. A redistributed tread void is intended to increase tread contact and dry traction. Tubeless construction is described as providing a seal without tubes.
Consider: The listed features emphasize dry traction and do not establish that this is a suitable everyday or wet-weather choice. Match the intended use and vehicle fitment before purchasing.
Buying Guide: How To Choose 20-Inch Mickey Thompson Tires
Which tread type fits your driving?
Choose an all-terrain model such as the Baja Boss A/T if you need a balance of road handling and off-road traction. The Baja Legend MTZ is the more aggressive mud-terrain-style choice in this group. For road-focused handling, compare the Street Comp. For dry drag-strip traction, consider the ET Street S/S.
How should you compare the two Baja Boss A/T versions?
Both listed versions use an asymmetric all-terrain tread design. The 275/60R20 SL version highlights wet and cold-weather traction and treadlife. The LT275/60R20 E version adds Extreme Sidebiters and Powerply XD construction features. Compare the full size and load specification, not just the product name.
What do size and load markings mean for your choice?
Do not assume that every 20-inch tire fits every vehicle with 20-inch wheels. The listed sizes vary in width, aspect ratio, construction, and load designation. Check the vehicle placard or owner’s manual and confirm that the tire’s size and load rating meet the vehicle’s requirements. Ask a qualified tire professional if fitment is uncertain.
Do you need wet-weather or winter features?
Look for features that match your conditions. The Baja Boss A/T descriptions mention wet handling or braking, and one listing provides a specific Three-Peak Mountain Snowflake designation statement. The Street Comp mentions wet-and-dry performance, while the ET Street S/S listing emphasizes dry traction. Do not infer a winter rating from tread style alone.
