Well that can depend entirely on how you drive. I have about 4,500 on my tire and it definately has a lot of life left. However; if you track race or zip around all the time expect to shave off about 1/2 to 3/4 of the tires life. Just plan on getting a new one when you cannot see much pattern on the tire. Of course it's always better to have newer ones than spent one's but i don't like spending the 150+ dollars on a new tire every month.
