Finding a set of tires that's tough enough to withstand on and off road conditions is a must for most commercial drivers. Fortunately, Roadmaster built the RM300 HH with these drivers in mind while also providing them with a tire that can perform under heavy loads. Stone protector ledges on the tire's lugs force out rocks, stones, and other debris to prevent damage, while the RM300 HH's cut and chip resistant rubber compound provides added durability. The RM330 HH includes a deep tread depth for excellent traction, and a curb bar for additional protection against curbing or scuffing.
