The Roadmaster RM257 Drive Tire from Cooper Tire features 18/32nds of tread depth on the 225 size and 19/32nds on the 245 size, as well as a Three-Peak Mountain Snowflake certification. It is an open-shoulder tire with three tread blocks in the center. The tire’s 3D siping allows for better grip in wet weather conditions, while staggered shoulder pockets and chevron grooves provide ideal bite and performance in snow and mud conditions. Lateral tie bars help stabilize the tread blocks to enhance even wear and promote better handling. The 19.5" tire comes in size 225/70R with load range F and G, and 245/70R with load range G and H.
