Frequently Asked Questions
What load range should I choose for my RV or motorhome?
Load range indicates the tire’s maximum safe load capacity and sidewall strength. RV tires typically range from Load Range C to Load Range E. We recommend checking your vehicle’s placard (usually on the driver’s door jamb) for the manufacturer’s recommended tire size and load range. Load Range E tires are standard for Class A and larger Class C motorhomes, while Load Range C or D may suit smaller Class B vans. Using a lower load range than recommended compromises safety and increases sidewall flex during highway driving. Always match or exceed the manufacturer’s specified load range.
How often should I check RV tire pressure and condition?
We recommend checking RV tire pressure and visual condition monthly, or before every extended trip. RV tires experience unique stress from sustained highway speeds and extended parking in direct sunlight, which can cause slow air loss and sidewall deterioration. Underinflation by just 5 PSI significantly increases sidewall fatigue and heat buildup, potentially leading to blowouts. Use a quality tire pressure gauge and inflate to the PSI listed on your vehicle’s placard, not the maximum PSI on the tire itself. Inspect sidewalls for cracks, bulges, or uneven wear, which indicate suspension or alignment issues requiring professional service.
What is the difference between ST-rated and LT-rated RV tires?
ST-rated (Special Trailer) tires are engineered specifically for trailers and motorhomes, with reinforced sidewalls optimized for the sustained-load, high-speed stress of RV applications. LT-rated (Light Truck) tires are designed for pickup trucks and vans, with slightly different load distribution and sidewall characteristics. In our research, ST-rated tires generally offer superior sidewall strength and durability for dedicated RV use, while LT-rated options provide more versatility for vehicles used in mixed applications. For full-size motorhomes, ST-rated tires are typically the better choice. For Class B vans and smaller RVs, LT-rated tires often provide acceptable performance with better all-season handling.
How do I prevent RV tire blowouts and sidewall cracking?
Blowouts and sidewall cracking result from underinflation, excessive heat, and UV exposure. We recommend maintaining proper tire pressure year-round, checking monthly and adjusting for temperature changes. Park your RV in covered storage when possible, or use tire covers to minimize UV and ozone exposure. Rotate tires every 5,000 to 7,000 miles to promote even wear. Avoid overloading your RV beyond the manufacturer’s GVWR, which increases sidewall stress. If you notice sidewall cracks, bulges, or uneven wear, replace the tire immediately. High-quality ST-rated tires with reinforced sidewalls, like the Goodyear Endurance, provide better crack resistance than economy alternatives.
What treadwear warranty should I expect, and what does it cover?
RV tire treadwear warranties typically range from 3 to 5 years or 40,000 to 60,000 miles, whichever occurs first. We researched manufacturer coverage and found these warranties generally cover defects in materials and workmanship, but exclude damage from underinflation, overloading, road hazards, or improper maintenance. Some manufacturers offer prorated refunds for tread wear beyond the warranty period. To maximize warranty coverage, maintain proper inflation, rotate tires regularly, and keep service records. Premium tires like the Michelin LTX M/S2 often provide extended warranties with strong manufacturer support, while budget options may offer limited coverage. Review your specific tire’s warranty terms before purchase to understand coverage limits and exclusions.
