The Dilemma of Motorhome Tires: When to Replace Them

When it comes to motorhome tires, the decision of when to replace them is a common worry. Even if your tires appear to be in perfect condition, they still need to be replaced due to their age. After all, nothing lasts forever, and the lifespan of motorhome tires is influenced by a variety of factors.

Why Age Matters: The Impact of Time on Tires

Although your tires might not show visible signs of wear, age deterioration can make them susceptible to carcass failure under load and heat. This is particularly concerning in motorhomes, which often sit for long periods without use. Even if your tires look great, there's no escape from eventual replacement due to their age.

General Tire Lifespan Guidelines

A general rule of thumb is that tires have a 10-year life span from the time they are manufactured. This life span is marked by a DOT (Department of Transportation) code on the sidewall. However, for larger truck tires, they can often last even longer as long as they are in good condition and not showing signs of cracking on the sidewalls. Regular movement can also help prolong their lifespan.

Specific Recommendations for Motorhome Tires

Motorhome tires should be replaced after 5 to 7 years, and it's essential to have them inspected by a tire professional. Unfortunately, finding an honest tire professional can be a challenge, as many so-called "experts" are simply tire salesmen who push the need for replacement. However, if you find a reputable inspector, they can provide valuable insight. I once had the pleasure of working with an honest tire professional who advised an inspection every six months. We continued to use these tires for another 1.5 years before they began to show numerous cracks, leading to their replacement.

Manufacturer Suggestions

Manufacturers suggest that motorhome tires should be replaced after 7 years. If you're concerned, it's a good idea to consult a tire dealer for a professional inspection. Pay close attention to any fine cracks in the rubber, as they can indicate the beginning of a deeper issue.

Personal Experience with Cooper Mastercraft AT3 Tires

My 99 Ram motorhome currently has a set of four Cooper Mastercraft AT3 tires with over 80,000 miles on them. The sidewalls are turning brown, suggesting signs of dry rot. Considering that these tires might dry rot before the tread wears out, I've decided to order a new set. Regular inspection and proper maintenance can help delay the need for replacement, but eventually, they must be replaced.

Preventing Premature Tire Failure

If your tires are dry rotting, Michelin tires are known to be the worst in this area. However, if your tires haven't started showing signs of dry rot, keep your tire pressures corrected and use them until the treads are worn out. This can help save you from the high cost of a tire blowout. For those who want to maintain fresher tires, many neighborhood tire shops offer tire trade-ins for your used tires, allowing you to keep a reserve of usable tires while also potentially reducing costs.

Conclusion

The decision to replace your motorhome tires is a crucial one. While they may seem fine, age is a significant factor to consider. By following the guidelines and regular inspections, you can ensure the safety and reliability of your motorhome while also potentially saving money in the long run. Always be cautious and make informed decisions to keep your motorhome on the road safely.
