Consumer Reports determines the speed a tire starts to hydroplane on standing water about 3/8-inch deep. Most all-season and performance all-season tires have good hydroplaning resistance, but winter tires can be great or miserable. Winter tires that have a tight tread pattern with lots of siping (slits) to bite into snow and squeegee on ice don’t resist hydroplaning well. These include the Nokian Hakkapeliitta R2 winter tire, which started hydroplaning at a relatively slow 45 mph, and not much better, were other popular winter tires including the Michelin X-ICE XI3, Bridgestone Blizzak WS80, Dunlop Winter Maxx, and Continental WinterContact SI. In contrast, tires with a blocky tread with lots open channels like the Firestone WinterForce do a better job of remaining in contact with the road. The Firestone started hydroplaning at an impressive 58 mph, just behind the best tire, the performance all-season Nokian enTYRE 2.0, which started hydroplaning at 59 mph.
