Where can i find a tire for my spare? I have gone on tire rack and nothing the tire size i am looking for 145 80 17. A fellow Z driver needed a help after blowing his spare on the highway so i gave him mine to get were he needed to go. I just ask to give me a new tire or the money but i have not been able to give him place to buy or how much it will cost.

dealership... or maybe www.infinitipartsusa.com

I tried sewellparts.com and the spare wheel is for sale but the tire isn't listed. Might be able to call them:

You checked ebay or the classifieds here for someone parting out a G?

I searched and found a few tires in that size (goodyear), but nobody would give me a price.

So do you live local that the guy could return the tire and be all good?
How far did he need to go on the spare?

Doesn't Fix-a-Flat mess up the tire pressure sensors?

Dunno, don't have TPMS

fix a flat messes da **** out of your tires and sensors and stuff...
