Tire/Wheel rotation 8.5's all around
 

A guy at Discount Tires says they have put the rear size tires (8.5) on the front of some Z's with sucess. That way they can be rotated front to back on the same side. After removing the spare-tire stud. Other than maybe an adjustment on the front offset,and re-installing the tire pressure sensors, would there be any problems? I saw somewhere a post that the VDC is calibrated for the 8.0 wheel in front (I have a performance model). I sure would like some feedback cause I just picked up a set on Ebay (stock Performance wheels), and was planning to use the rear 8.5's in front when it's time to replace the tires. Thanks and please respond.

You can do it, no problems other than slightly throwing the VDC off and also the fron will stick out slightly further than the rear relative to the fender....

Here is a link that discusses this.
