I have the ss tsl radials and when the odometer hits 60,000 miles(160 miles away)I will have had them on for 14,000 miles,and the tread wear right now is about an eigth lost.I know this because I have a matching spare that has never hit the road.The fronts will get wavy if you dont rotate them every 5,000 miles ???They are a better tire then poeple give em credit for.Way better than the bias ply (as far as mileage)that I have owned in the past.
