So one of my tires seems to have developed a slow leak. I'm debating about how best to handle it. My car has 11k on it, and the tires are about 7/32" depth, so they aren't worn out. But one new tire with full depth is going to be pretty drastic. So what do you think I should do? Beyond getting the one tire checked out to see if it can be plugged if it's got a nail in it or something.
