Maintaining trailer tires — whether they are ST (Special Trailer) or LT (Light Truck) — isn’t always the same as what you do for passenger vehicle tires. Here are some basics on getting the most out of your trailer tires.
1. Maintain the Right Trailer Tire Pressure.
Running your ST or LT trailer tires under-inflated is a sure way to quickly wear them out and invite tire failure. Keeping them at the proper air pressure is key for longevity, load-carrying capacity, and the ability for the tire to dissipate heat better.
The best way to tell if your tires are properly inflated is to check them with an air pressure gauge. In some cases, an under-inflated tire may not appear low. Trailer tires can look fully inflated and be below the safe air pressure.
