Thunderer OA421

FEATURES AND BENEFITS

• Enhanced controllability
• Upgraded load durability
• Longer lasting tread life

OVERVIEW

The Thunderer OA421 is a highway terrain， all season tire manufactured for commercial vehicles. It was made for the vehicle's drive axle.

The maintained surface contact of the symmetric ribbed tread block placement and the solid shoulder ribs enhances the controllability. The better road contact allows the tire to improve the steering responsiveness and the driving stability. In other words， it allows the tire to be quicker and more precise in its response to the driver's commands， while the structure is secured against the driving pressure affecting the tire. This combination greatly improves the steering axle's control over the vehicle， as it ensures the drive axle's better handling.

The model features a stronger internal structure which maintains the ideal tire shape under the pressure. The reinforced construction does not allow the tire to deform under the load and driving pressure. As the tire does not deform under the pressure， it is able to securely carry and withstand heavy loads with ease. In this manner， the tire significantly upgrades the load and driving durability， optimizing the performing capacity.

The OA421 improves the length of the tread life. The stability of the footprint and the durable compound work together to greatly enhance the tread life. The footprint manages to evenly distribute the driving pressure across the tread area， avoiding premature and irregular wear formations across the tread area. On the other hand， the durable compound also avoids damage to the tread area. The strengthened compound elements avoid the tread's chipping， cracking and tearing， preventing them from shortening the service life.
