Techking's TKHardy is an alternative tire solution for mining trucks and is available in 10.00R20 (18PR), 11.00R20 (18PR), and 12.00R20 (20PR) sizes. Designed to perform 85% in off-road conditions and 15% on-the-road, the TKHardy features the company's Hardy formula, which offers an improved cut and impact resistance compound, as well as a strong hard-core design on the bead area to support heavier-than-standard loads. Techking's Inno-Formula reduces heat generation speed inside the tread area. The line offers quality inner tube and flaps and a tread depth 7.5 mm (3 in) narrower than the estimated time-over-target (ETOT) line. TKHardy is suitable for mining trucks in less severe road conditions after ETOT and is suitable for most difficult terrain operations.
