When a tyre is used on an SUV, the strength and durability of the tyre tread is not enough. The sidewalls must also resist cuts and punctures. The durability of the versatile Nokian Hakkapeliitta 7 SUV's sidewalls is improved by special side impact protection that provides much-needed additional strength.
The tyre's rubber compound also improves its durability. The rubber compound of the Nokian Hakkapeliitta 7 SUV is adjusted for winter use on SUVs. The mixture of natural rubber and silica offers good wear resistance. The compound also uses rapeseed oil that adds tear strength in addition to grip on ice and snow. Tear strength means that the tyre can resist the negative effects of sharp rocks when driving on difficult terrain, for example.
