Buying Guide
What size should I choose? The 37×13.50R20 and 37×13.50R22 options fit common dually setups; verify wheel well clearance and load rating for your truck before purchase.
Are these tires more for off-road or on-road use? Options like STT Pro and Baja Boss A/T emphasize off-road traction, while Ragnarok One and Venom Power aim for well-rounded all-season performance. Choose based on your typical driving conditions and terrain.
What does load rating and ply mean? Higher ply (12- to 10-ply) generally supports heavier loads and tougher terrain but can affect ride comfort and fuel economy. Ensure your vehicle’s suspension and rims are compatible with the tire’s load rating.
How important is treadwear warranty or mileage rating? A higher treadwear rating can indicate longer life, especially for highway use. Consider treadwear alongside tread pattern and construction when evaluating durability.
What about tire compatibility with rims and sensors? Verify wheel size, offset, and sensor compatibility for 37-inch tires on your truck to avoid rubbing, speedometer errors, or sensor issues.
