Spare Tire Diameters w/Posi Unit
I'm trying to organize a spare tire combo unit that works with the big brake set-up I have. I've purchased a 2005-07 GTO spare, and with a 1" wheel adapter the rim fits over brakes both front and back. (KORE 3) The wheels adapter is barely necessary, and some might hack on the caliper but I'm not.
The temporary tires diameter is 25.375, but the rear tires on my car are 26.5" tall> I've found a M H front drag skinny which fits the GTO rim-185/55R17, and the diameter of this tire is 26.0.
My question is would this diameter be close enough, and not create stress for the posi-unit given the need for temporary driving in case of a flat tire?
I'd appreciate any other ideas or feedback.
Thanks
