Technology

Asiatech has developed and fully tested its own proprietary RADIAL tyre technology for passenger car, light truck, OTR (Including mining), and all-steel Truck & Bus (TBR) tyres

• Technology is MODERN and includes UHP passenger Tyres, large SUV tyres Up to 24” bead diameter as well as the latest Super Single TBR

• “Technology” includes Compounding, Tyre Design & Development, Process specification and control, testing to ECE and FMVSS standards

• Asiatech TBR tyres were successfully tested at Smithers Scientific Services in 2007, comparing favorably against Tier 1 manufacturers

BIAS vs. RADIAL TYRE TECHNOLOGY

BIAS (CROSS-PLY) TYRE

BIAS or cross-ply tyre technology has its roots in the beginning of the 20th century.

Tyre casing consists of a number of layers of cord, whereby cord plies cross with a bias angle to the central tread surface. The casing can be reinforced by a breaker of fabric or steel.

BIAS tyre has a flexible tread and a rigid wall. In contrast to the RADIAL tyre, it has a higher rolling resistance and generates much more heat. Due to a higher rate of the tyre tread wear, the life of a BIAS tyre is much shorter than the life of a RADIAL one. The only advantage over the RADIAL tyre is a lower probability of tyre wall damage. BIAS tyres are still popular in many developing countries with poor road conditions and frequent overloading of vehicles.

RADIAL TYRE

RADIAL tyre technology was invented by Michelin in 1948, but it took about 30 years to come to prominence with the leading OEM manufacturers.

RADIAL tyre casing consists of cord layers which are positioned at 90° (+0°/-5°) angle to the tread surface. The casing is reinforced by breakers running under the tread which absorb the load stress along the tyre surface. In contrast to the BIAS tyre the RADIAL tyre has a much stiffer tread and more flexible tyre walls. Vehicles fitted with RADIAL tyres can operate at a much higher speed and load. The degree of radialization of passenger car and truck & bus markets in the developed countries is close to 100%. Globally this ratio is about 65%.
