Double Coin and CMA recently added new tire sizes for their RLB452 open shoulder drive-position tire and RR202 5-rib highway service tire.

The RLB452 features a four-belt package and an open shoulder that allows debris to escape from between the tread lugs. Increased biting edges across the tread surface can help enhance grip and traction on dry or slippery road surfaces, and long wear is achieved by a 28/32nds tread depth.

“We have not introduced a new open shoulder drive tire in a very long time,” said Tim Phillips, VP of marketing and operations for Double Coin/CMA. “Furthermore, we want our loyal customers to know that we are not discontinuing the older RLB1 open shoulder drive tire.”

The new RR202 315/80R22.5 20-ply is a heavy-duty commercial truck tire for multiple applications. This 5-rib tire is built for improved handling and traction, and features protective sidewall ribs to reduce curb damage and abrasion.

 “The RR202 is really a diverse tire,” added Phillips. “Depending on the size, we have also seen this tire perform well in off highway or mixed service applications.”
