OVERVIEW
The Roadmaster RM257 is a highway terrain, all season tire manufactured for commercial trucks. This model was made for the drive axle of the vehicle.
This model's aggressive tread design boosts surface contact and improves controllability and driving stability, even in different weather conditions. The shoulder block pattern and its wide sipes offer excellent road contact and upgrade steering responsiveness. The steering response time is faster and more precise to the driver's command. This tread design enables the driver to maintain an easy and comfortable control over the vehicle all the time.
The special tread design and the all season compound enhance year-round traction. The tire is able to significantly boost road surface grip with extra biting edges. The strong tire compound keeps the tire flexible during hot summer and cold winter weather temperatures. The tire sports the Three Peak Mountain Snowflakes symbol which means that the tire is certified to perform in harsh winter weather conditions. Wide open shoulders and stone ejector grooves disperse water, slush, snow, and dirt from the tread area, and with that improve road contact and prevent hydroplaning.
The Roadmaster RM257 aggressive tread design manages to avoid irregular wear formations, by evenly distributing load and driving pressure across the tread area. The durable compound effectively slows down the treadwear rate during the performance. This model, with the high tensile steel belt structure, prevents irregular and premature wear formation, which offers longer tread life.
