Slush and aquaplaning

Rainwater that lingers in the ruts of roads places demands on driving. When the ruts are deep, the risk of hydroplaning is high, but anticipatory driving and good treads can reduce the risk.

New tyres are the best weapons against hydroplaning. A tread pattern that channels water out from between the tyre and the road is the most effective means of preventing hydroplaning. According to test results, hydroplaning starts at 76 km/h (47 mph) when cornering on worn out tyres (groove depth below 1.6 mm), whereas the corresponding speed for new tyres is 96 km/h (60 mph).
