Mastercraft Glacier MSR is M+S rated winter tire manufactured for light pickup trucks and SUVs. This tire designed to provide confidence and control during winter driving. With more contact area than its predecessor, Glacier MSR sticks to the road better, providing the driver with stability and control in challenging winter weather conditions. Its tread design features multiple sipes scattered across the whole surface of the tread and help to trap the snow to enhance the grip and reduce slipping in harsh winter conditions. With additional stud placement, Glacier MSR can provide an exceptional grip and traction on icy roads, so whenever the conditions turn extreme, these tires will be ready to support you. Mastercraft Glacier MSR bears a three-peak mountain snowflake (3PMSF) symbol, meaning it is severe weather rated and can be driven in the most challenging winter conditions.
