Unlike on every other WRC round, drivers only have one type of tyre available at Rally Sweden. But it’s a pretty special tyre. The Pirelli Sottozero Ice J1B – as used by the Rally1 and Rally2 cars – features 384 tungsten-tipped studs. Each stud measures 20 millimetres in length, seven millimetres of which protrudes from the tread. This bites into the ice surface to provide excellent grip and make Rally Sweden’s breathtakingly high speeds possible.
