man, I'm getting so many conflicting posts from you guys that I don't know what to think...
would it be easier/more logical to stretch the tires less - like making a 17 stretch to 18"? I have a bunch of 15's sitting in the garage and I just can't see trashing them.
Wantsti - can you send me a picture of the stretcher you have? Manual or hydraulic? I'd prefer not to sweat since I'd be paying so much to use it, but I'm pretty sure I'll make my money's worth either way!
