Pair of BKT AT 171 38×10-20 Mud Tires (2) By BKT
The BKT AT 171 is a mud-focused tire designed for ATV use with a 38×10-20 sizing, offered as a bundle of two tires. The 6-ply construction provides enhanced puncture resistance while maintaining flexible sidewalls for off-road traction. Suitable for ATV applications that require a wider footprint for improved flotation in soft mud and sandy conditions. The tire’s aggressive tread pattern aims to maximize grip when navigating slick surfaces and deep ruts, reducing wheel slip in muddy terrain.

Buying Guide
Key considerations when choosing 38-inch mud tires for 20-inch rims include tire size compatibility, load and speed ratings, and tread pattern design. A few perspectives help ensure a well-rounded decision:
- Fitment and compatibility: Confirm the tire’s overall diameter and width align with your vehicle’s fender clearance, suspension travel, and wheel offset. A 38-inch tire on a 20-inch wheel may require lift or leveling to avoid rubbing and to maintain steering geometry.
- Terrain and traction: Mud-terrain tires emphasize aggressive tread blocks and voids for mud release. For rocky or sandy roads, look for staggered tread patterns and reinforced sidewall construction to resist punctures and improve grip.
- Durability and construction: A 6-ply or higher rating adds puncture resistance, while sidewall reinforcements help protect against rocks and stumps. Consider the tire’s load rating to ensure it supports the vehicle’s weight and payload.
- Mileage and warranty: Mud tires often have shorter tread-life expectations than all-terrain designs. Review manufacturer warranties and road-hazard protections, especially if you frequently drive on rough surfaces.
- Road performance: Off-road tires can exhibit more road noise, stiffer ride, and fuel efficiency changes. Some models balance aggressive traction with quieter highway performance; prioritize based on your driving mix.
- Maintenance and rotation: Regular rotation, proper balancing, and alignment help maximize tread life and even wear on mud tires, especially on vehicles with aggressive wheel setups.
Other considerations include using the appropriate lug nuts and hardware for the 6×139.7 bolt pattern, ensuring wheel load ratings match the combined weight of the tire and vehicle, and verifying available aftermarket support for lift kits and fender clearance. Consumers should weigh the trade-offs between maximum mud traction and on-road comfort when selecting tires for daily driving versus dedicated off-road use.
