ive had my tires (37s) for 2 1/2 years. i still have 55ish% if you keep up on the alignment they will last and last. its great. any time i noticed it starting to pull more than it should (lets say letting go of the wheel and it will drift within under 5 seconds) id redo the alignment. best DD wheeler tire i think personally. get them.
your tires have more then 55% left
