Michelin Latitude Tour HP All-Season Radial Tire - 275/55R17 109V 2-D Active Sipes help deliver better handling in rain and snow by locking together for greater rigidity. Experience a stable feel and crisp steering at high speeds thanks to precisely placed polyester and aramid/nylon filaments (FAZ Technology) under the tread. Aramid is the material that makes bulletproof vests bulletproof. Save money at the pump thanks to a combination of a fuel efficient tire shape and tread compounds which reduces unnecessary friction when the tire rolls.
