Looking for a 13 inch wide tire to use to mess around with putting together wheels and spacing/offset etc. It doesn't have to be good as it won't be going on the track. I will be going to the Fremont and Indy swap meets if anyone has any they can part with.

Also looking for a 92" 12.5" wide tire. I understand no such tire has even been built (by Hoosier anyways), so that might be kind of tough. I'd be happy with something close.
