Coach Tires 8.25R20 Long Mileage Bus Tires, Durability and Excellent Grip
Features
The durable coach tire of 8.25R20 with 14-ply or load range G, is designed for the all wheel position of the intercity buses with high speeding, there are 2 sizes being available of 7.50R20 and 8.25R20.
This bus tires have the feature of excellent performance of the abrasion resistance, which ensuring its mileage service and increasing the durability of this coach tires.
For the purpose lowering the rolling resistance of the tires, increasing its’ wear resistance and extending the service mileage, the application of four main circumferential grooves of the tread pattern, and combined with applied low heat built-up tread compound, can effectively lower the heat accumulation of this coach tire of 8.25R20, improve tire' wear resistance and increase durable of the tire, and its' feature of the low rolling resistance, which providing the low fuel consumption.
The application the S type sipes combined with zigzag treads, which improving the bus tire' grip performance on dry and wet grounds, and promotes coach tire' performance resistance to the uneven wear and performance against to the sideslip.

Application
By now, the small buses and mini-coaches are still mainly traveling traffic tools for those people lived in villages and towns that being far away the downtown. These vehicles being configured with the products of tubed tire including the sizes of 7.50R20, 8.25R20, 7.50R16, 7.00R16, and 6.50R16, running on fixed route that alternated with rough terrain and good pavements, they need tire products with the features of long mileage and excellent grip performance.
According the reports from WALSTONE marketing investigators, the frequently braking on sloping pavement will accelerate the worn and torn of the tread of tires, so the manager of those coach fleets tend to utilize the tire products with high wear resistance to low their operating cost.
Actually, tire’ wear performance will be effected by many factor, such as tire’ rolling resistance, the performance of heat build-up and heat dissipating.
The application of cooler tread compound which providing the lower heat build-up, and combined with the rib groove of tread pattern design, can lower rolling resistance, to increase the wear performance, and improve tire’ mileage service.
And the tread pattern design with zigzag type, promotes the grip performance and braking performance of this coach tire of 8.25R20 on the sloping pavement.
