Product Overview

Severe Weather Rated
Studdable
M+S Rated

The Discoverer M+S is Cooper’s premium studdable winter SUV/light truck tire designed for drivers looking for excellent traction on snow and ice. The Discoverer M+S line fits a wide range of SUVs and light trucks, foreign and domestic.

Strategically-Placed Stud Pin Holes

Provide enhanced stud retention while delivering optimum traction on ice.

"D Squared" D2 Sipe Technology

A dense zig-zag sipe pattern further enhances winter performance while maintaining excellent wet traction. The sipes are deep to provide performance benefits throughout the life of the tire.

"Snow-Groove" Design Technology

Provides biting edges for excellent snow and ice traction without reducing tread element stiffness. Capitalizes on the higher traction characteristics of "snow on snow" versus "snow on rubber."
