Frequently Asked Questions
What is the difference between ST and LT tires for trailers?
ST (Special Trailer) tires are specifically designed for trailers and prioritize high load capacity, resistance to sidewall flex, and durability for non-driven axles. LT (Light Truck) tires are designed for light trucks, vans, and SUVs, balancing load capacity with traction and handling for powered axles. While some use LT tires on trailers, ST tires are generally engineered to better handle the unique demands of trailer towing, such as resisting scrubbing during turns and supporting static loads for extended periods.
How do I determine the correct load range for my trailer tires?
To determine the correct load range, you need to know the Gross Vehicle Weight Rating (GVWR) of your trailer and divide it by the number of tires. This gives you the minimum load capacity each tire must support. Always select a tire with a load range and load index that meets or exceeds this calculated value, and match the original equipment specifications as closely as possible. The load range indicates the ply rating equivalent, such as Load Range C, D, or E, which corresponds to specific maximum load capacities at a given inflation pressure.
What is the recommended tire pressure for heavy duty trailer tires?
For heavy duty trailer tires, the recommended tire pressure is almost always the maximum inflation pressure indicated on the tire’s sidewall. Unlike passenger car tires where pressure is adjusted for ride comfort, trailer tires need to be inflated to their maximum cold PSI to ensure they can carry their full rated load and to minimize heat buildup and sidewall flex. Always check the tire manufacturer’s specific recommendations and your trailer’s placard.
How often should I replace heavy duty trailer tires?
Even with good tread, trailer tires should typically be inspected and considered for replacement every 3 to 5 years, regardless of mileage. They are prone to ‘aging’ from UV exposure and prolonged static loads, leading to sidewall cracking and internal breakdown. Always inspect for signs of wear, cracking, bulging, or damage before each trip. Frequent use at maximum load or in harsh conditions may necessitate earlier replacement.
Can I use passenger car tires on a heavy duty trailer?
No, it is strongly advised against using passenger car (P-metric) tires on heavy duty trailers. Passenger tires are not designed to handle the unique stresses of trailer use, such as continuous heavy static loads, significant side-to-side scrubbing during turns, and the absence of a driven axle. Using P-metric tires can lead to premature wear, excessive heat buildup, reduced stability, and a significantly increased risk of tire failure, which can be dangerous and costly.
