Спецшины Sportrak SP359

Sportrak SP359 – a specialized model for all-wheel drive KAMAZ trucks and special equipment operating in extreme road and climate conditions. The tyre is designed as a universal tool for vehicle fleets used in logging, quarries, and marshy terrain. Its key task is to provide off-road capability and load-carrying capacity where asphalt ends.

All-terrain tread pattern

The tread features deep, wide lugs with a developed shoulder area. This geometry provides effective grip with loose, viscous, and icy surfaces, as well as efficient evacuation of mud and water from the contact area. Thanks to the optimized void ratio, the tyre actively self-cleans. And the increased depth of the "cut" guarantees a long service life even under intense loads.

Strength reserve

The design is built on a reinforced diagonal carcass with 22 layers. This solution provides exceptional resistance to punctures, cuts, and tears. A multi-layer breaker with metal cord additionally reinforces the shoulder areas, reducing deformation under load and preventing delamination.

Special features of the rubber compound

Particular attention in production is paid to the compound recipe. The maximum content of natural rubber ensures high elasticity at negative temperatures. At the same time, the polymer matrix is reinforced with technological additives that increase resistance to wear and thermal oxidative aging. As a result, a balance is achieved between tread life and resistance to mechanical damage.

Flexibility of operation

One of the key features of the model is the possibility of significant reduction of internal pressure. When driving on sand, marshy terrain, or deep snow, reducing pressure expands the contact patch, reduces the specific pressure on the ground, and radically improves off-road capability.

Key features of Sportrak SP359:

- optimal fitment sizes and load parameters fully comply with the factory requirements for all-wheel drive KAMAZ trucks;
- a self-cleaning tread with a depth of 25 mm guarantees confident movement through mud, sand, snow, and ice;
- a layering index of 22 and a load index of 167 provide high load-carrying capacity and resistance to punctures;
- increased natural rubber content maintains elasticity and grip at temperatures down to –45°C.
