Спецшины BKT Earthmax SR 25 Plus

In the world of road construction and mining, compromises are unacceptable. BKT Earthmax SR 25 Plus – a model created for machines that operate where ordinary tyres fail in a matter of hours. Graders and loaders involved in the most demanding road construction and mining conditions – this is the native environment of this tyre.

Steel base

The main design solution is a all-steel carcass. Unlike tyres with textile cord, where the load is taken by polymer threads, here each power layer is made of steel cord. This gives a tremendous advantage in conditions of increased risk of punctures and cuts. The metal structure provides optimal pressure distribution in the contact patch. The tyre does not "fold" under the weight of the equipment, but works as a single power structure. When driving over sharp rock fragments or rebar, the steel cord withstands impact loads that would tear a textile carcass.

Traction where others slip

The second key element of the engineering concept is a non-directional tread pattern. Such architecture provides equally high traction characteristics when moving in any direction. This is critically important for graders operating in a shuttle method.

Tread pattern

The grooves between the blocks are designed so that dirt, clay, and small gravel are thrown out of the tread when the wheel rotates. Stability on any surface – from rocky base to loose soil – the grip remains at a high level. The tyre dampens vibrations even in the most unfavorable conditions, reducing the fatigue of the machine operator.

Protection against wear and cuts

The model is made from a compound with increased resistance to cuts. Special polymer additives at the molecular level increase the material's resistance to mechanical destruction. The tread does not "crumble" when in contact with sharp edges and maintains the integrity of the working surface throughout the entire lifespan.

Key features of BKT Earthmax SR 25 Plus:

- specially designed for graders, front loaders, and wheel bulldozers operating in road construction and open-pit mining conditions;
- all-steel carcass provides exceptional strength, puncture resistance, and cut resistance;
- tread pattern guarantees high traction properties when moving in any direction, excellent self-cleaning from dirt, and stability off-road;
- withstands up to 6900 kg per wheel, which corresponds to the heavy operating conditions of special equipment.
