![]() ![]() There are two nominated manufacturers for WRC 2017 season: Michelin and DMACK. Soft tyre will offer maximal grip, but will wear quicker. In general, hard tyres are used when the temperatures are high (usually above 22☌) and soft tyre when it’s colder (0–10°c), while a super soft option is for sub freezing temperatures, used in Rally Monte Carlo. So they need a tyre for each of the conditions, while these need to be adjusted also on the conditions - surface temperature, where there are 4 options: super soft, soft, medium, hard. ![]() In season 2017 there are 13 events, from which 8 are entirely on gravel, 2 on tarmac, 1 on snow and two mixed (Monte Carlo - tarmac/snow, RACC - tarmac/gravel). And for easier perspective, we’ll look only into World Rally Championship. So how do they achieve that?įirst of all, we must look at all different conditions that rally drivers face during the season. Rally tyres must offer the best grip possible at high speeds in any conditions and any surface.
