Trailer Tires 101

Trailer tires see a little bit different kind of service. Trailer tires don’t have to steer or deliver torque to the road, but they do have to handle loads (sometimes very heavy loads). That means that trailer tires have to be pretty robust, and need to hold up at high speeds and long service lives.

We’re happy to offer Gladiator trailer tires! Gladiator makes tires for commercial trucks, RVs and other vehicles, as well as a line especially designed for trailer service. Gladiator tires are radial designs and approved for highway speed use.

  • Gladiator QR25-TS – The advanced tread compound of the Gladiator QR25-TS is designed for reduced heat under heavy loads, as well as improved rolling resistance and fuel economy. Steel belted construction for strength, smooth ride and long tread life.

  • Gladiator QR35-TR(AS) – The QR35-TR(AS) features steel belts for stable ride and handling, long service life and uniform wear, with a pattern of five wide ribs for stability. Specially-designed shallow tread especially for trailer use.

  • Gladiator QR35-TR – Another in the Gladiator trailer tire line, the QR35-TR features a wide 5-rib tread design and shallow tread pattern for highway trailer service.

Tips to Remember for Trailer Tires

  • Trailer tires are designed for trailer axle positions only. They are not intended for drive or steering axles, and shouldn’t be used in those positions.
  • Check inflation when tires are cool and out of the sun, and make sure that trailer tires are always inflated to the maximum PSI indicated on the sidewall. Underinflation is the worst enemy of your trailer tires, and the number one cause of failure.
  • Don’t exceed your trailer tires’ load capacity. The combined capacity of the tires must meet or exceed the Gross Vehicle Weight (GVW) of the axle. The combined capacity of all the tires has to exceed the weight of a loaded trailer by 20 percent.
  • All tires need to be the same size; if they are replaced with taller tires, the tongue height of the trailer may need adjustment for the right load distribution.
  • Time, heat and the elements take their toll on a trailer tire. Over the course of three years, you can expect about one-third of the tire’s strength to be compromised.
  • Remember that trailer tires do not have the life expectancy and tread wear of vehicle tires. The tread wear for a trailer tire is only about 5000-12000 miles, and trailer tires should be replaced every three to four years regardless of mileage, appearance or tread depth.
