Wet, snow, oil, or ice: This Michelin city tire can conquer it all. The star tread, originally designed as a shoe sole grippy enough not to slip on an oiled stainless steel plate, gives studded tire security. Star-shaped lugs made of snow tire rubber bite into terrain from pavement to dirt, even in the coldest temps. High-density nylon inside prevents punctures from hidden obstacles.
