Several factors can influence how often should RV trailer tires be replaced with mileage, age and the type of driving done all important.
RV trailer tires typically need replacing every 3-5 years, regardless of mileage. But if you cover a lot of miles on the road, that lifespan is significantly reduced.
Guide to RV Trailer Tire Replacement
When you’re hitting the open road in your RV, the last thing you want is a tire blowout. Not only can it ruin your trip, but it can also pose a serious safety risk.
You need to know all about RV trailer tires as a van owner and know when and why you should replace them.
Understanding RV Trailer Tire Lifespan
Most RV enthusiasts are surprised to learn that their trailer tires typically need replacement every 3-5 years, regardless of mileage. This is because RV tires often age out before they wear out.
Factors like UV exposure, ozone, and temperature fluctuations can cause tire degradation even when your RV is parked.
Don’t wait for a blowout to replace your tires. Here are some indicators that it’s time for new rubber:
- Visible cracks or dry rot
- Tread wear below 2/32 of an inch
- Bulges or blisters on the tire sidewall
- Uneven wear patterns
- Age (5+ years old)
Choosing the Right Replacement Tires for an RV
When it comes to RV trailer tires, you have two main options:
Special Trailer (ST) Tires
Designed specifically for trailers, these have stiff sidewalls to support heavy loads and withstand high temperatures.
Light Truck (LT) Tires
Some RV owners are opting for LT tires due to their higher speed ratings and better heat resistance.
Each type has its pros and cons, so consider your specific needs and consult with a tire professional before making a decision.
To maximizing tire life and get the most out of your RV tires you should maintain proper inflation pressure, rotate tires regularly, clean tires with mild soap and water and cover tires when storing the RV.
The Cost of Safety
Quality RV tires aren’t cheap, typically ranging from $200 to $350+ each.
However, when you consider the potential cost of a blowout – both in terms of repairs and safety – it’s clear that investing in good tires is worth every penny.
What Are The Best Practices for Maintaining RV Trailer Tires?
Check tires before every trip for signs of damage, cracking, bulging, or uneven wear and maintain the recommended tire pressure.
Ensure your RV is loaded evenly and doesn’t exceed the gross vehicle weight rating (GVWR) to prevent excessive stress on tires.
It’s recommended to rotate tires regularly, typically every 5,000-7,000 miles or at least once a year, and have wheels balanced when mounting new tires, during rotation or after flat repairs.
Frequently Asked Questions
How often should I inspect my RV tires?
Perform a visual inspection before every trip and at least monthly during storage periods.
Can I use regular car tires on my RV trailer?
No, never use passenger tires on a trailer. Always use Special Trailer (ST) or Light Truck (LT) tires designed for heavy loads.
What’s the biggest difference between ST and LT tires?
ST tires have stiffer sidewalls for stability but lower speed ratings. LT tires offer higher speed ratings and better heat resistance but may have lower maximum inflation pressures.
How can I tell the age of my RV tires?
Look for the DOT code on the tire sidewall. The last four digits indicate the week and year of manufacture.
What causes premature RV tire wear?
Common causes include improper inflation, excessive sun exposure, overloading, high speeds, and prolonged storage without use.
