The Cooper DISCOVERER STT PRO is an all-season summer all-terrain tire. It has been designed with an alternating rib 3-2 of the tread, which gives the tire a unique design to reduce noise and increase its stability. This tire is fitted with stone-ejection ribs and its alternating shoulder relief will improve grip in mud and on soft surfaces. It is a tire specially designed for vans. It’s the most extreme off-road tire Cooper has ever offered! If you are looking for off-road performance while maintaining excellent traction on the road, this tire is for you!
