In response to the person that stated that a 225/70R15 tire shouldn't go on a 15"X7" steel rim, if they go to TireRack.com and look in the tech section on tires it lists what size rim a particular tire should be mounted on.   The Michelin tire I mounted on the rim was within their recommended limits.   You can't go by a certain tire size and know all the rim sizes it fits.   Use TireRack.com for a particular tire you are interested in and then research to see what size rims will fit (or vica-versa).   Just thought I would let you good folks know the facts.
