Roadmaster RM275

Long Haul Drive
With deep 27.5/32" tread depth and solid shoulder ribs, the RM275 is designed to deliver long tread life in highway haul service while the center tread elements provide traction in wet and snow.

Engineered for Retreadability
A cool-running base compound, combined with the 4-belt construction is designed to resist stone penetrations, to deliver the durability and retreadability fleet owners expect.

M+S Rated
