The Road Ahead: Your Essential RV Trailer Tire Buying Guide
Choosing the right tires for your RV trailer is vital for safe and enjoyable travels. Trailer tires carry heavy loads and face different stresses than car tires. This guide helps you pick the best set for your adventures.
Key Features to Look For
Several important features define a good RV trailer tire. Pay close attention to these when shopping:
- Load Range (Ply Rating): This tells you how much weight the tire can safely carry. Always match or exceed your trailer’s maximum weight rating (GVWR). A higher load range means a stronger tire.
- Speed Rating: Trailer tires often have lower speed ratings than car tires. Never exceed the maximum speed listed on the sidewall.
- Tire Size: This must match exactly what your trailer manufacturer recommends. You find the size (like ST205/75R14) on the old tire or the sticker inside your RV door.
- ST Designation: Look for “ST” (Special Trailer) on the sidewall. These tires are built specifically for trailers, handling side-to-side stress better than standard passenger tires.
Important Materials and Construction
The materials inside the tire greatly affect its performance and lifespan.
Most quality trailer tires use a strong internal structure. They feature steel belts beneath the tread. These belts keep the tire flat on the road, which reduces trailer sway. The rubber compound itself is another key factor. A good compound resists cracking caused by sunlight (UV rays) and ozone exposure, especially important since trailers often sit unused for long periods.
Factors That Improve or Reduce Tire Quality
What makes one tire better than another? It often comes down to how it handles long waits and heavy loads.
Quality Boosters:
- Stiffer Sidewalls: Strong sidewalls prevent the tire from flexing too much when you corner or when the trailer is fully loaded. This reduces heat buildup.
- Heat Resistance: Since trailers often sit, and then travel long distances under load, excellent heat dissipation is necessary. Better construction sheds heat effectively.
- Fresh Date Codes: Always check the date the tire was made. Older tires, even unused ones, degrade.
Quality Reducers:
- Underinflation: Running tires too soft causes excessive sidewall flexing, which quickly leads to dangerous heat buildup and blowouts.
- Overloading: Exceeding the load range puts incredible stress on the tire casing, guaranteeing premature failure.
- Exposure to Elements: Leaving tires uncovered in direct sunlight for years breaks down the rubber faster.
User Experience and Common Use Cases
Your travel style dictates the best tire choice. Think about where you drive and how often.
Long-Haul Travelers: If you cover thousands of miles each summer, prioritize tires known for high heat resistance and superior load-carrying capacity. Premium brands often excel here.
Seasonal Campers: If your RV sits parked for nine months of the year, focus on tires with excellent resistance to dry rot and UV damage. You may want to cover them when stored.
Off-Road/Boondocking: If you frequently leave paved roads, you might look for tires with a more aggressive tread pattern for better grip, though these are less common in the standard ST category.
RV Trailer Tire Buying FAQs
Q: What is the difference between a trailer tire and a car tire?
A: Trailer tires (ST) have stiffer sidewalls designed to support heavy, vertical loads and resist sway. Car tires (P) are built for comfort and handling rather than sheer weight capacity.
Q: How old is too old for an RV trailer tire?
A: Most manufacturers recommend replacing trailer tires after six years, regardless of tread depth. Check the DOT date code on the sidewall for the manufacturing week and year.
Q: Should I use passenger tires on my RV trailer?
A: No. Passenger tires cannot safely handle the unique stresses and heavy, constant loading of an RV trailer. You must use tires marked “ST.”
Q: What does Load Range D mean?
A: Load Range D is a measure of the tire’s strength, usually indicating it can handle higher inflation pressures and heavier weights than a Load Range C tire. Check your trailer manual for the required range.
Q: How often should I check my tire pressure?
A: You should check the pressure before every trip and then again about once a month if the trailer is in use. Always inflate to the MAX PSI listed on the tire sidewall, not the pressure listed on the RV frame sticker (which often refers to minimum pressure).
Q: What causes tire blowouts on trailers?
A: The two main causes are severe underinflation, which creates too much heat, or overloading the tire beyond its rated capacity. Both lead to structural failure.
Q: Do I need special tires for tandem axles versus single axles?
A: You need tires that meet the weight requirements for the whole trailer. However, trailers with two or more axles need slightly more load capacity because the tires share the weight, but the side scrubbing during turns puts extra stress on the inner tires.
Q: What is “scuffing” or “scrubbing” on tires?
A: This happens when the tire treads drag sideways while turning, common on multi-axle trailers. Good quality tires with stiff sidewalls handle this scrubbing better.
Q: Can I repair a trailer tire puncture?
A: Minor punctures in the tread area can often be professionally repaired. However, sidewall damage or punctures near the shoulder area usually mean the tire must be replaced immediately for safety.
Q: What is the best way to store my trailer tires?
A: Store the trailer in a cool, dark place. If possible, use UV-blocking tire covers. If the trailer is parked for months, place wooden blocks under the frame so the weight is off the tires entirely.
