ROADMASTER RM272™
Cooper Tire & Rubber Company
The RM272 is an all-position/trailer tire featuring a premium, high-scrub tread compound that provides improved treadwear and solid, long-lasting protection against cutting and chipping in spread axle trailer applications. It is also well suited for straight trucks and recreational vehicles where stopping and starting occur frequently. The stone ejector ribs in the grooves help preserve the casing for retreading and the rounded shoulder design help minimize the effect of high lateral forces on the tire.
