## Overview

## Description

The Cooper Discoverer S/T Maxx tire is a commercial grade traction tire that will outlast general purpose tires in service work and overloading conditions that are hard on tires and cause rapid tire-wear. The Cooper Discoverer S/T Maxx tire is a balanced tire for highway and city driving, as well as off-road when traction is needed in mud, and dirt. The rubber used in the sidewall, and the silica blended tread compound provide enhanced wet traction and delivers excellent cut and chip resistance on rocky terrain. The tire profile has also been tuned to perform even when overloaded. If you are hard on your tires, and need to avoid downtime associated with tire problems, take a close look at the Discoverer S/T Maxx - definitely a tried and true tire with a loyal following.

Review: Have these tires on my 2020 3500 Denali dually, great ride quality and very minimal road noise. Have around 55,000 miles (mostly towing a 40' flatbed gooseneck) on them now and they are about 30% tread. Will be buying the same tires again!
Review: Very happy with these tires. Good ride for a load range E rugged terrain tire. Was impressed with snow traction. I did not even have to engage 4WD on a snow covered steep hill in a relatively light weight Gladiator Pickup. Ice is less good, but to be expected. Fuel economy dropped, but I increased diameter over 2 inches and moved from a highway tire so to be expected.
