What Would Jalopnik Do?
TL;DR of this morning's commute is that I got forced over a curb and took a chunk out of the sidewall on my right-rear tire. It's not leaking air but it's not something I'd stake my life on very long. Being a rear tire I was planning to rotate it and its mate to the front next spring. Now I'm confronted with a choice.
* Buy four new tires (~$400) even though the remaining ones are only 9 months old.
* Buy only two new tires, put them on the front, and rotate my slightly-worn fronts to the back as I was already planning to do.
The car in question is a 2010 Mazda 3S, which is, of course, FWD, since that makes a difference.
