The new Extreme Country mud-terrain tire has been designed with a proven tread compound for excellent traction, responsive handling, even wear, longer life, and a quieter ride. The tire delivers stability and responsive grip on irregular surfaces with tight inner void/ large surface area tread elements to provide greater contact area for better handling and a quieter ride. It also features a heavy duty carcass that enhances sidewall strength. Wide outer tread voids and angled shoulder scallops provide better traction in mud and loose soil to get you and your truck through whatever nature can dish out. Extreme Country tires are offered in 25 popular sizes to fit most trucks and feature a mud and snow (M+S) rating.
