Pirelli’s new rally tyre for snow and ice, which has studs longer than 8mm, will make its first appearance this weekend. Fitted to R5 cars on the Arctic Rally from 15-16 January, the Sottozero Ice WJ debuts at the opening round of the Finnish Rally Championship. Its long titanium-tipped studs are locked into place using Pirelli’s patented vulcanisation process for retention. A new tread pattern design helps the tyre to capitalise on the increased grip supplied by the studs. Pirelli says the new tyre will be available commercially for national championships run in extreme winter conditions, such as those run in the Scandinavian and Baltic regions. It is suitable for R5, R2 and historic rally vehicles.
