Expensive screw....

MacCool

2011 Sport Touring. Got in it yesterday morning and tire pressure warning was lit. Right rear was down 10 lbs. I aired it up checked it later that day and it was down again. On inspection, I found a small foreign object in the center part of the tire. I though no problem, I'll go get it patched. I figured it would be better to pull it myself rather than risk the tire shop putting it on the rack, so I removed the tire. Unfortunately, on doing so I found that the little thing in the middle of the tread was just a little rock and there was a big sheet rock screw on the outside edge, about 1/2 inch from the sidewall .

Took it to the local National Tire & Battery - they're the only tire store in the area with a "no-touch" tire machine (whatever that is) and locally known for special care in dealing with expensive wheels. $460 installed and balanced for a Potenza 275/35-19

I guess I could have gone cheaper - would have saved about $50 overall from Tirerack.com. Oh well...next time.
