Cordiant Professional DR-1 295/75 R22,5 144/141L (Ведущая ось)

The commercial tire Cordiant Professional DR-1 is designed for installation on the drive axles of trucks that operate on both regional roads and highways. With a relatively low cost, the model is characterized by excellent reliability and durability, making it possible to use it to improve the economic efficiency of commercial vehicle operation. Another advantage is its traction properties on wet pavement, comparable to those of leading global brands.

Lamelles Constant Depth Sipe

The tread of the tire features a large number of lamellas, special knife-like cuts. They are made to half the height of the blocks, giving them additional functionality. These tread elements, when in contact with the road surface, form multiple edges. This allows the tire to demonstrate improved performance when starting, accelerating, and braking, especially on wet pavement. At the same time, the depth of the cut allows the blocks to deflect under load, increasing the size of the contact patch and enabling the tread to better absorb road irregularities.

Effective stone protection

The longitudinal grooves, designed primarily for drainage, also perform other functions due to the presence of additional elements in their design. In particular, special protrusions prevent stones from getting stuck in the tread, minimizing the risk of mechanical damage. This significantly increases the tire's lifespan on poor roads.

Reinforced sidewalls

This model is characterized by high load-carrying capacity, even for its category. This is largely due to the design of the sidewalls, which contain an additional steel cord. In addition to increasing the tire's load-carrying capacity, it gives the sidewalls an elliptical shape under load, ensuring a more even distribution of pressure across other force elements and the contact patch. In addition to increasing load-carrying capacity, this improves the tread's resistance to wear.

Saves fuel

Using this tire allows for significant fuel savings. The savings are achieved by reducing rolling resistance. This is the result of several technical solutions. One of them is the very rigid construction of the carcass and sidewalls, which, thanks to their all-metal design, are extremely resistant to deformation. Another factor is the tread design. All the numerous blocks are arranged longitudinally, and their geometric shapes feature rounded corners and edges. The latter are directed parallel to each other or at a large angle. All this improves fuel efficiency, as well as driving and acoustic comfort.

Main features of Cordiant Professional DR-1

- lamellas cut to half the depth of the tread improve longitudinal traction while providing a smooth ride;
- special elements at the bottom of the longitudinal grooves for drainage prevent stones from getting stuck in the tread;
- sidewalls with an additional steel cord have an elliptical shape, increasing load-carrying capacity and preventing uneven wear;
- the stiffness of the carcass and sidewalls, combined with the optimized arrangement and shape of the blocks, reduces rolling resistance and, consequently, fuel consumption.
