Commercial drivers long for a tire that's built to last and can save them time and money at the pumps. Designed for long haul and highway applications, the RM852 EM from Roadmaster does all of this and more thanks to its special rubber compound that improves fuel efficiency. 3D micro gauge siping on the shoulder enhances traction in challenging weather conditions, and the RM852 EM's uniquely designed tread lugs allow for even wear. The RM852 EM features a deep, wide tread design and asymmetric groove walls to help drivers receive longer mileage.
