Description

The Cooper Discoverer STT Pro is an extreme off-road tire for light trucks, built for strong off-road performance without giving up on-road traction. Armor-Tek3 internal construction reinforces the casing for greater resistance to damage on boulders and rough ground.

An aggressive high-void tread with mud-release dimples keeps clearing tread to dig in, stone ejectors help protect the casing, and alternating shoulder lugs with a 3-2 center block pattern keep good road manners on the highway.

In the LT38X13.50R20 light truck size, this tire has a 123Q load and speed rating, load range D. Specs include 21/32-inch tread depth, a 50 psi maximum inflation pressure, a UTQG rating of 780AA and an overall diameter of about 38.19 inches.
