Walked out of work today to find that the first day I get the mach out for the year I pick up a screw in the back right tire and it's sitting on the rim. No big deal because I'm getting new tires this month anyway. So I put the spare on and drive it home about 20 miles. Now that I'm home I'm curious if running a 18 inch wheel on one side and the stock smaller spare on the other could have hurt anything in the rear end? It didn't make any sounds or anything but I was just wanting to be sure? May be a dumb question but never hurts to ask! :beer: thanks guys!
