The best 40-inch off-road tire depends on your terrain, vehicle requirements, and how often you drive on pavement. The Mickey Thompson Baja Boss M/T is best for shoppers seeking specified puncture-resistance and handling features, while the Milestar Patagonia M/T-02 is aimed at light trucks and SUVs that regularly leave paved roads. The options below include mud-terrain tires and a specialty 18-inch tire; check tire and wheel fitment before ordering.
| Tire | Listed size | Best for |
|---|---|---|
| Mickey Thompson Baja Boss M/T | 40X13.50R17LT | Mixed driving and off-road traction |
| EFX MotoRavage XL | 40X10R18 | Buyers seeking a narrow 18-inch option |

Mickey Thompson Baja Boss M/T
The Baja Boss M/T is a 40X13.50R17LT tire with a C load range designation in its listed name. Its asymmetric tread pattern is designed to balance off-road traction with on-road handling and reduced noise. Extra-large Four-Pitch SideBiters add another stated off-road traction feature.
Best for: Drivers who want a 40-inch mud-terrain tire with features aimed at both trail use and pavement driving. The Powerply XD construction adds heavier-denier cord to the angled third ply, which the product description says supports puncture resistance, steering response, and stability.
Limitation: An aggressive mud-terrain design may not suit buyers seeking a quiet, road-focused tire. Confirm the tire’s dimensions and load requirements against the vehicle before purchase.
EFX MotoRavage XL 40X10R18
This EFX MotoRavage XL is listed in 40X10R18 sizing and as an 8-ply tire. Its 10-inch stated width distinguishes it from the 13.5-inch-wide options in this guide, so it may be worth considering when the narrower listed size better suits the buyer’s setup.
Best for: Shoppers specifically seeking a 40-inch tire listed for an 18-inch rim, with a narrower 10-inch width and an 8-ply designation. The supplied product information identifies it as the MotoRavage XL.
Limitation: The available feature information is limited; it does not specify tread design, terrain focus, or on-road behavior. Verify those details and vehicle fitment before choosing it over a more fully described tire.
Maxxis Razr MT MT-772
The Maxxis Razr MT MT-772 is listed as a 40X13.50R17 tire with a C/6-ply designation and a black sidewall. The supplied specifications state a 40-inch outer diameter, 13.5-inch width, and 17-inch rim size, making the dimensions easy to compare with other tires in this roundup.
Best for: Buyers looking for a 40-inch, 13.5-inch-wide tire for a 17-inch rim and who want the product’s core dimensions stated clearly. Those measurements can help narrow a comparison, but they do not replace checking the vehicle’s approved fitment and clearance.
Limitation: The provided feature list does not describe tread details, wet-road behavior, or construction beyond the C/6-ply designation. Get additional product specifications if those factors are important to your decision.
Mickey Thompson Baja Legend MTZ
The Baja Legend MTZ is listed as a 40X13.50R17LT 121Q C tire. Its bold MTZ tread styling is described as supporting on- and off-road performance. The T4 silica-reinforced compound is intended to provide wet handling and braking performance, cut-and-chip resistance, and tread life.
Best for: Drivers comparing 40-inch mud-terrain tires who value stated wet-performance and durability features. Its PowerPly three-ply sidewall construction is described as adding puncture resistance and more responsive handling.
Limitation: The tire’s aggressive tread styling is oriented toward mixed on- and off-road use, not a dedicated pavement-first buyer. Check the vehicle’s load and size requirements before selecting this specification.
Milestar Patagonia M/T-02
The Milestar Patagonia M/T-02 is listed as an LT40X13.5R17 light-truck tire with a 128Q D designation. It is designed for light trucks and SUVs that frequently drive off-road. Large voids in its aggressive tread pattern are intended to provide traction on challenging terrain, while cross-directional siping is described as helping create a stable footprint and reduce chunking risk.
Best for: Light-truck and SUV owners seeking a 40-inch mud-terrain option with features specifically described for frequent off-road driving.
Limitation: Its feature description emphasizes off-road use rather than road comfort or noise. Compare load requirements and confirm clearance before purchasing.
Buying Guide: How to Choose 40-Inch Off-Road Tires
What size and wheel details should you check?
Start with the full tire-size designation, not just the 40-inch diameter. These products include 17-inch and 18-inch rim sizes, and widths ranging from 10 to 13.5 inches. Confirm that the tire’s rim diameter matches the wheel and that the vehicle has the required clearance. A tire’s listed dimensions alone do not confirm fitment.
Which tread features matter for your terrain?
For mud and challenging trails, look for descriptions of aggressive tread blocks, large voids, and side-biter features. The Milestar listing calls out large tread voids, while the Baja Boss lists Four-Pitch SideBiters. For mixed pavement and trail use, compare features that specifically mention road handling, noise, or wet braking rather than assuming all mud-terrain tires behave alike.
How should you compare construction and load designations?
Check the complete size and load information against the vehicle’s requirements. The listings include C and D load range designations, ply information, and load or speed codes in some product names. These labels are not interchangeable. Use the vehicle manufacturer’s specifications and the tire’s complete product details to confirm an appropriate match.
What if you drive on pavement regularly?
Give extra attention to stated on-road handling, noise, and wet performance. The Baja Boss description mentions reduced noise and on-road handling; the Baja Legend description highlights wet handling and braking. These are product features, not a guarantee of performance in every vehicle or condition.
