Nokian Powerproof RunFlat

Nokian Tyres positions the Powerproof in the UHP category. The company worked with former F1 world champion Mika Häkkinen during product testing. The Powerproof tread pattern is asymmetric and features three wide main ribs. The tyre utilises the Dual Zone Safety concept also seen on the Wetproof; in this instance, the latter’s Stability Zone is replaced by the virile-sounding Power Zone. Nokian says this outer shoulder area “ensures precise handling.” It is paired with the Wet Safety Zone on the inside of the tread. This entry refers to the run-flat version of the tyre.
