CONTINENTAL TKC 70 Rocks - The fourth challenger in Continental's 2020 tire assault is the TKC 70 Rocks – a rear tire without a solid backbone and with knobs over the entire tread pattern. It's a cross between the TKC 70 and TKC 80 and can be used on wider types of terrain than the TKC 70 and is better on the road than the TKC 80, offering an attractive alternative with greater versatility and freedom. The TKC 70 Rocks can be combined with the front wheel tires of the TKC 70, creating an additional tire option for those who yearn for the horizon offroad.
