Courser MSRTM

Overview
The Courser MSR is a premium winter light truck tire and SUV designed for drivers seeking excellent traction on snow or ice. Mastercraft snow tires are pinned for studs where studded tires are not prohibited by state laws.

Severe Weather Rated
Studdable

"D-Squared" Sipe Technology
Further enhances winter performance while maintaining excellent wet traction. The sipes are deep to provide performance benefits throughout the life of the tire.

Patented "Snow-Groove" Design Technology
Provides biting edges for excellent snow and ice traction without reducing element stiffness. Enhances the retention of snow in the outer circumferential grooves to capitalize on the higher traction characteristics of snow on snow versus snow on rubber.

Enhanced Studded Performance
The stud pin hole design improves stud retention and the number has been increased allowing for the use of a greater number of studs for better traction on ice. The stud size is conveniently molded into the sidewall for easy reference.
