The best 40-inch truck tire depends on your wheel size and how you use your truck. The Maxxis Razr MT-772 is a direct option in either 17-inch or 20-inch rim fitment, while Mickey Thompson’s Baja Boss M/T emphasizes off-road traction with on-road handling. The Baja Legend MTZ combines aggressive tread styling with features aimed at wet-road performance. One supplied product is a small solid equipment tire, not a truck tire, so it is included only to clarify the difference.

Maxxis Razr MT-772 40-Inch, 17-Inch Rim
This Maxxis Razr MT-772 is listed with a 40-inch outer diameter, 13.5-inch width, and 17-inch rim size. Those dimensions make it the direct choice in this group for a buyer seeking a 40-inch tire specified for a 17-inch wheel.
Best for: Truck owners whose planned wheel size is 17 inches and who want the listed 40 x 13.50R17 configuration. It was selected because its supplied specifications clearly identify both the tire diameter and rim size.
Check before buying: The listing details provided do not state a load rating or vehicle fitment. Confirm the tire’s requirements against your truck, wheels, and intended use before ordering.
Mickey Thompson Baja Boss M/T 40-Inch
The Baja Boss M/T is listed as a 40 x 13.50R17LT tire with a 121Q C designation. Its asymmetric tread is described as balancing off-road traction with on-road handling and reduced noise. Extra-large four-pitch SideBiters are intended to add off-road traction, while Powerply XD uses heavier-denier cord in the angled third ply for puncture resistance, steering response, and stability.
Best for: Buyers who want a 17-inch 40-inch tire with features directed at both off-road use and road manners. Choose this model if the SideBiters and reinforced-ply construction match your priorities.
Check before buying: The product details do not establish that this tire is quiet in every vehicle or suitable for every driving condition. Verify fitment and load requirements for your truck.
Mickey Thompson Baja Legend MTZ 40-Inch
This 40 x 13.50R17LT tire is described with bold MTZ tread styling for on- and off-road performance. The listed T4 silica-reinforced compound is intended to support wet handling and braking, cut and chip resistance, and tread life. Its PowerPly three-ply sidewall construction is described as adding puncture resistance and more responsive handling.
Best for: Buyers comparing 17-inch 40-inch tires who place emphasis on wet-road features and sidewall protection. It stands out in this selection for its stated compound and three-ply sidewall construction.
Check before buying: These are product-described benefits, not a guarantee of performance in every vehicle or road condition. Confirm the tire’s specifications suit your setup.
Maxxis Razr MT-772 40-Inch, 20-Inch Rim
This version of the Maxxis Razr MT-772 is listed with a 40-inch outer diameter, 13.5-inch width, and 20-inch rim size. It shares the model name of the 17-inch option, but the rim size differs, making wheel measurement essential when comparing the two.
Best for: Buyers building around 20-inch rims who want a listed 40 x 13.50 tire. It was selected as the 20-inch counterpart to the 17-inch Razr option.
Check before buying: The supplied features do not include a load rating or detailed vehicle compatibility. Do not assume it fits a truck solely because the diameter matches; check the required wheel and vehicle specifications.
AR-PRO Solid Tire And Wheel, 10-Inch
This AR-PRO product is not a 40-inch truck tire. It is a 10-inch, flat-free solid tire and wheel assembly in a 4.10/3.50-4 size, intended for equipment such as hand trucks, wheelbarrows, dollies, and utility carts. Its solid rubber construction requires no air, and the listing states a dynamic load capacity of up to 500 pounds per tire.
Best for: Equipment owners replacing a compatible small solid tire. It is included to distinguish the supplied non-truck product from the four 40-inch truck tire choices.
Not for: Truck buyers seeking a 40-inch tire. The listing cautions against prolonged static loading for best performance.
Buying Guide: How To Choose A 40-Inch Truck Tire
Which rim size do you need?
Start with your wheel diameter. The supplied truck tire options here specify either a 17-inch or 20-inch rim. A 40-inch outer diameter does not make those versions interchangeable: the tire must match the wheel it is designed for. Check the size printed on your current tire and confirm your wheel measurement before selecting a listing.
How wide is a 40 x 13.50 tire?
The listed Maxxis Razr options specify a width of 13.5 inches. The Mickey Thompson products are identified as 40 x 13.50R17LT. Compare the full tire size—not just the 40-inch diameter—with your vehicle and wheel requirements. The provided product information does not specify clearance, so verify that independently for your setup.
What features matter for off-road and road use?
The Baja Boss M/T listing highlights SideBiters, an asymmetric tread, and Powerply XD construction. The Baja Legend MTZ listing emphasizes a silica-reinforced compound and three-ply sidewall. These stated features can help narrow a comparison, but they do not replace checking the tire’s complete specifications for your vehicle and driving needs.
What should you verify before ordering?
- Confirm the exact tire size and rim diameter.
- Check load and vehicle requirements using the complete product specifications.
- Consider whether your use prioritizes off-road traction, road handling, wet conditions, or puncture resistance.
- Do not treat small solid equipment tires as truck tires; the AR-PRO model is a different product category.
Frequently Asked Questions

No. The products listed here specify a 13.50-inch width, but buyers should check the full size of any tire they consider.
Can I use a 17-inch tire on a 20-inch wheel?
No. The listed 17-inch and 20-inch options are specified for different rim diameters. Match the tire to the wheel size.
Which listed tire is intended for wet handling?
The Baja Legend MTZ listing describes its T4 silica-reinforced compound as providing wet handling and braking performance.
Is the AR-PRO tire suitable for a truck?
No. It is a 10-inch solid replacement tire and wheel for small equipment, not a 40-inch truck tire.
