I have an 07 STS 1SF with the 18" wheel option. Will the 18" wheel with a 255/45/18 tire fit in the place of the existing spare? I know I could jack up the car and remove one to check, but if someone has already done this, does it fit?

Probably won't. I have a 2006 with 235/50 17 tires/wheels and it does fit in the wheel well, but tightly, and spare tire cover has to be turned upside down.

rb92gt, thanks for the info. If the 235/50/17 is tight, then the 255/45/18 won't fit then. Calculating the overall diameter, it is about 3/4" too big

So, when you have a flat, you slide that big ole dirty tire in the trunk, right?

Remember the Pontiac Fiero - A removed wheel and flat tire would not fit in the front compartment and allow it to be closed, so you left it along the side of the road and hoped to retrieve it later. :crying2:
