Spare Tire ?s

Wont a tire smaller than whats on the car cause problems if you have a sure grip? The smaller tire turning
faster and all...........
Yeah, after a while it will. But how far, and at what speed do you plan to drive on the spare? The 155R14 tire pictured is 23.8" diameter, a little small IMHO. You can get a 25.8" tire in the well, however they are all a little to "thick" and the trunk floor ends up with a small hump in the middle. That's what I wound up getting, a 195/70R15C Goodyear Cargo G26.
