This is maximum safe carrying capacity of the tire. A higher Load Range allows the tire to carry a heavier load. The tire comes with a sidewall that has Raised White Lettering.

The Discoverer STT Pro is formulated with a rugged, wear resistant compound that molds into a dynamic, high-void tread pattern. The tread is optimized to combat stone retention which, in turn, extends tire life. The tread pattern features a hybrid 3-2 tread pattern that minimizes road noise and maximizes ride stability. This tire is equipped with alternating shoulder lugs that bolster traction on soft, muddy road surfaces. Furthermore, mud release dimples expel loose soil from the tread for a confident ride no matter where you're traveling.
