Check your tire pressures

JARblue

I drove off the lot with one tire pressurized around 75 PSI. Got about halfway home (~10 mi) before vibration started and steadily increased. By the time I detoured to my friend's house nearby, the rear driver tire had a bulge on the inside sidewall about the size of a football (will upload pic when I get home - added, see below). Put on the spare and drove it back to the dealership. They got me fixed up and on my way, but seriously, wtf...

So I called my mechanic friend who helped me out with the tire on my way home after picking up the car about a month ago. He reminded me we let quite a bit of air out before even checking the pressure (which measured over 70 psi). I was taking pictures when the thing started making noises so we hustled to deflate it a bit.



I note that while there is a TPMS, it detects underinflated tires only. Why not have a PSI range with alerts when pressure strays beyond? I can't imagine having to deal everything that might have happen if the tire had blown

My only question is: Why? I get the 45 to 50 PSI for transport, you don't want flat spots during the couple weeks the car sits on a boat, but why would the dealer inflate a tire to 75 PSI? I hope they got you a new tire and not just deflated it for you...

I had already called my sales guy and told him to have the tech aware of my situation. Since I refused to put a dirty a$$ tire in the back of my brand new Z, I left it at my friends house. When I got to the dealership, they gave me back the loaner Z to go pick up the dirty tire lol. When I got back, I had to wait about 15 min for my car - they had some trouble finding another sports package rim to put on my car.

The first thing the service manager said when I walked in the door was "Have you called the tire manufacturer?" I wanted to punch him in the nutz, but to that point my experience had been very pleasant so I just assumed he was joking. They gave me a new rim and tire without any hassles.
