I was just given a set of tires that i plan to use for trail use only. I'm not planning on putting a lot of street miles on them. They have some dry rot/cracking. My budget is tight and the tires have very little wear, so, is there a goo/product that could be painted inside the tire to seal small cracks. any kind of "chemical re-vulcanizing(made up term) ?? the only thing spent so far is elbow grease getting them off the truck they were on, so i dont mind spending a few bucks if i could get a little more miles out of 'em. j. in b'ham

 

You cannot simply "seal" the cracks. The rubber is old and brittle, and dry rotted. DO NOT run those tires on the street, they can blow out and cause a big accident.
