Tires: Specifically P225 75R15. The tires on my 76 Olds Delta daily driver are 8 yrs old, cracked and out of balance. So just get a new set, right? Not so easy. None of the majors tire brands carry that size with white stripe: only blackwall and RWL. Found some made in China, but want to avoid those after my last experience on some 700-15 for an old truck where they had weights spread over 1/4 of the rim. One recommendation was for P735 70R15, but the tire shop could not supply comparison dimensions. It ain't supposed to be this hard what used to be a common size tire. Recommendations? Willie
