Thanks Dave O., I am trying to keep it pretty original. I just bought six 700x18's for "Big Orange" ($$$$ ouch) and will use the factory rims. I have experiece with the split style rims and will probably just do them myself. If you don't hear from me in the next couple weeks.....send an ambulance!! I do like the fire ring idea though. I have a bunch of 8.25 20's I think I'll do that with!
