> I've been driving for 36 years now and have never had a tired damaged more than the very occasional puncture.
I typically go through a tire a year. The city I live in (Seattle) will pay to replace the tire if the loss was due to a pot hole, but you have to take a picture of the pot hole, which can be a bit hard to do in many circumstances.
There have been years where I've paid more for tires than for gas. :/
