Quick question on a 2001 toyota avalon. How long would anyone think that they last. It's no doughnut thats for sure, it seems to be full sized, and I know I can look on the side of the tire for specs, or check the manual, but I was just wondering if anyone knew of the top of their heads. I am at work right now, and don't want to run out and check, and since I am bored with nothing to do, figured I would give this a shot.
