Bad luck

I swear, Jason and I have the worst luck with tires on our car. When we owned our Saturn, we bought a new set of tires every year and a half or so because the car wasn't designed correctly and wore through them too quickly (and that was with getting them rotated every time we got an oil change). Now the Camry doesn't wear through them the way the Saturn did, but Jason just had another flat tire today. We keep driving over crap in the road and of course they are never patch-able. So J went to change the tire today and discovered that the screws were stripped so he also had to have the car towed to a tire shop. The tow driver said he sees that all the time with people from Firestone (and I'm sure other places) because they get lazy and tighten it too tight with the air gun. So then when you have to change it yourself, it strips the bolts. We had a flat tire earlier this year with the exact same problem. We're not taking our car to Firestone any more for other reasons (really bad service), but here's another reason not to. It's so frustrating!
