Full set of Motosport EFX MotoRavage XL (8ply) 37×10-15
The Motosport MotoRavage XL 37×10-15 tires are 8-ply radial units designed for aggressive UTV use. Best for rock-strewn trails and aggressive off-road courses where puncture resistance matters. The four-tire bundle fits most standard UTVs and provides balanced front-to-rear handling. Caution: as a high-durability option, they may be heavier than lower ply models, potentially affecting ride feel on smoother surfaces.
System 3 RC500 37×10-15 (10ply) Radial
The RC500 model from System 3 Off-Road is a 10-ply radial tire sized 37×10-15. It emphasizes heavy-duty construction and rock-friendly traction, making it suitable for serious rock crawling and gnarly terrain. Best for heavier UTVs or riders who encounter sharp obstacles. Limitation: higher ply count can increase ride stiffness on uneven, smoother trails.
BFGoodrich Mud-Terrain T/A KM3 37×12.50R20
The BFGoodrich KM3 37×12.50R20 is a mud-terrain model with Krawl-TEK technology for improved rock traction. Best for drivers who traverse rocky hills and deep mud while needing reliable bite and durable sidewalls. A potential limitation is fitment—ensure wheel width and overall tire height meet your UTV’s clearance and suspension clearances.
KANATI Mud Hog M/T 37×12.50R20
The Kanati Mud Hog M/T set features 10-ply rated radial construction and aggressive ¾” tread depth. Best for heavy-duty rock and mud applications with high load capacity. Choose this if you need robust sidewall protection and extended puncture resistance. Limitation: weight and rolling resistance may be higher than lighter 8-ply alternatives.
Buying Guide
- Size and fit: Confirm the tire size matches your UTV’s wheel diameter and overall clearance. 37×10-15 and 37×12.50R20 are common choices for larger UTVs but require proper suspension travel and fender clearance.
- Terrain focus: If you frequently encounter rock ledges, choose tires with strong sidewalls and rock-specific traction features (e.g., KM3, Mud Hog M/T). For mixed terrain including mud, consider tread patterns that shed dirt efficiently.
- Durability: Ply rating affects puncture resistance and load handling. Higher ply (10-ply) offers more protection but can impact ride comfort and speed.
- Load capacity: Heavier UTVs require tires with higher load ratings. Review the tire’s recommended load to avoid under- or over-inflation issues.
- Rim and clearance considerations: Ensure your rims accommodate the tire width and that the tire’s height won’t rub frame components or suspension at full suspension travel.
- Maintenance and replacement: Consider availability of replacements and the ease of patching or replacing a punctured tire in remote locations.
Frequently Asked Questions
- What does 37×10-15 mean?
Answer: It denotes a tire 37 inches tall and 10 inches wide, designed for 15-inch wheels. - Are 10-ply tires worth it for a UTV?
Answer: They provide greater puncture resistance and load capacity, beneficial for aggressive rock crawling and heavy machines. - Can I mix tire brands on a UTV set?
Answer: Mixing brands is possible but can affect handling; for best results, use matched tires on front and rear when possible. - What should I check before mounting 37-inch tires?
Answer: Check clearance, suspension travel, wheel width compatibility, and whether your 37-inch tire is approved for your UTV model. - Do all 37-inch tires fit stock suspensions?
Answer: Not always; some setups require lift kits or trimming to prevent rubbing on rocks or during articulation. - Which tire is best for rock traction?
Answer: Tires with reinforced sidewalls and aggressive rock-specific tread patterns (e.g., KM3, Mud Hog M/T) generally perform well on rocks.
