It's too bad we don't have full size spares, otherwise I'd say just replace the wheel w/ the spare.
Actually, good point, that reminds me. I pulled out of an end parking space (luckily I backed in) and I forgot how close to the curb I was. I hit the curb with my rear tire and that tire saved my rim for sure. I have the Michelin Primacy.I noticed on the CT's at my dealer that the Michelins have a bit of rubber that protrudes out further than the rim. I guess this doesn't help?
