Read the article.. It talks about the sidewall cracking
I always though Dry Rot was in the tread.
True story.. Had a tire with dry rot hit something and go PSSSSSSSSSST (flat) Took it to Wal*mart (this was on a car, nto a motor home and it happened at less than 5MPH so it was not a big problem)...
Ask the guy how much for a new tire
HE starts explaining the advantages of a proper patch over a plug (I know more about it than he does).. I said "That's good but I ask how much for a new tire" Still he's trying to explain patch over plug... Finally I showed him a spot on the tread he says "YOU NEED A NEW TIRE"... Uh, is that not what I'd been asking for?????
