Commercial drivers who have heavy hauling applications need to make sure their tires are built to withstand the heavier weights. Fortunately, Roadmaster designed the RM230 HH+ line with these drivers in mind as its unique tread compound was specifically designed for use in heavy hauling applications. A deep tread depth is meant to extend the tread life, and the RM230 HH+'s stone protector ledge guards the tire from damage by rocks, stones, and other debris. Offering drivers a high load carrying capacity, the RM230HH+ has a built in sidewall depth indicator that visually shows drivers when their tires need to be rotated.
