The best 37-inch truck tire depends on your terrain, wheel size, and preferred tread. The Landspider Rocktraxx is a mud-terrain option for 17-inch wheels, while the Venom Power Terra Hunter X/T suits buyers seeking a wider extreme-terrain tire for 20-inch wheels. The Kanati Mud Hog and BFGoodrich KM3 emphasize off-road traction; the AMP Terrain Attack A/T is an all-terrain option with limited listed specifications. Confirm tire size, load requirements, and vehicle clearance before buying.
| Tire | Listed size | Best suited for |
|---|---|---|
| Landspider Rocktraxx M/T | 37×12.50R17 | Mud terrain and 17-inch wheels |
| Venom Power Terra Hunter X/T | 37×13.50R20 | Extreme terrain and 20-inch wheels |
| Kanati Mud Hog MT | 37×12.50R17LT | Aggressive off-road use |
| BFGoodrich Mud-Terrain T/A KM3 | 37×12.50R17/D | Rock and mud traction |
| AMP Terrain Attack A/T | 37×12.50R20 | All-terrain tread preference |
Landspider Rocktraxx M/T
The Landspider Rocktraxx is a mud-terrain radial tire sized 37×12.50R17 for light trucks. Its listed specifications include an E load range, 10-ply rating, 128Q service description, all-season traction, and a stated 50,000-mile treadwear figure. Raised black letters provide a distinct sidewall style.
Best for: Truck owners seeking a 17-inch mud-terrain tire with a stated treadwear figure and E-rated construction. It is a useful comparison choice when a 12.50-inch section width is preferred over a wider 13.50-inch option.
Consider: Its mud-terrain design may not suit buyers who prioritize a less aggressive tread. Check that the wheel and vehicle are specified for this size and load rating.
Venom Power Terra Hunter X/T
This extreme-terrain radial is listed as 37×13.50R20 for light trucks. The product details specify E load range, a 10-ply rating, 127Q service description, all-season traction, and a 50,000-mile treadwear figure. It has one black sidewall.
Best for: Buyers with a 20-inch wheel setup who want a 37-inch extreme-terrain tire and a wider 13.50-inch listed size. It is better suited to shoppers comparing 20-inch options than owners seeking a 17-inch fitment.
Consider: The 13.50-inch width differs from the 12.50-inch size of several alternatives here. Verify vehicle clearance and wheel fitment rather than assuming the tires are interchangeable.
Kanati Mud Hog MT
The Kanati Mud Hog MT is listed in 37×12.50R17LT size. Its product description highlights an aggressive angled tread, large void ratio, and wide footprint for off-road traction. It also specifies 3-ply sidewalls intended to add strength and impact resistance.
Best for: Drivers who put off-road performance first and want a tire described for mud, rocks, and varied terrain. The stated 3-ply sidewalls are a relevant feature for shoppers comparing construction details.
Consider: The listing explicitly identifies this as the tire only, not a rim. Plan for a separate wheel if needed, and confirm the exact size and fitment before ordering.
BFGoodrich Mud-Terrain T/A KM3
The BFGoodrich KM3 is listed as a 37×12.50R17/D radial tire for light trucks, SUVs, and crossovers. Its description emphasizes grip on rocks and slick surfaces. BFGoodrich states that it delivers 5% better mud traction and 8% better rock traction than previous models, with Krawl-TEK technology supporting rock climbing.
Best for: Off-road drivers prioritizing mud and rock traction, especially those comparing manufacturer-stated performance improvements with the prior model.
Consider: This is a mud-terrain tire aimed at serious off-road use. Choose it for its stated terrain focus, not on the assumption that it offers the same driving characteristics as an all-terrain tire.
AMP Terrain Attack A/T
The AMP Terrain Attack A/T is listed as a 37×12.50R20 tire with an E load range, 10-ply rating, and 126R service description. The product data identifies it as an all-terrain tire and lists package dimensions of 37 by 37 by 13 inches.
Best for: Buyers comparing a 20-inch all-terrain option rather than a mud- or extreme-terrain-labeled tire. Its listed 12.50-inch width may appeal to shoppers who do not want the 13.50-inch width of the Venom Power option.
Consider: The supplied listing details do not provide treadwear, traction, or sidewall information. Check the complete product specifications and vehicle requirements before deciding.
Buying Guide: How To Choose 37-Inch Truck Tires
Which wheel size and tire width do you need?
Start with the full size, not just the 37-inch diameter. The products here include 17- and 20-inch wheel options, plus 12.50- and 13.50-inch widths. A tire must match the wheel diameter, and its width and overall fit must work with the truck. Check the vehicle and wheel requirements, including clearance, before choosing.
Do you need mud-terrain, extreme-terrain, or all-terrain?
Choose a tread category based on where the truck will be driven. Mud-terrain options such as the Landspider, Kanati, and BFGoodrich are explicitly positioned for off-road traction. The Venom Power listing identifies an extreme-terrain design, while the AMP is labeled all-terrain. The provided specifications do not establish that one category is best for every driver.
How should you compare load details?
Compare the tire’s service description and load range with the vehicle’s requirements. The listed Landspider and Venom Power tires are E-rated and 10-ply rated; the AMP is also listed as E/10-ply. The BFGoodrich listing gives a D load range, while the Kanati details provided do not state a load index. Do not select a tire based on size alone.
What listing details deserve a second check?
Confirm whether the product includes a tire only or a wheel as well; the Kanati listing says it is only the tire, not the rim. Also compare sidewall and tread information, verify the exact size, and review the complete product listing for specifications not supplied here. Treadwear figures and performance statements apply only as described in the individual listings.
