High speed rated radials

If you're dealing with Performance Plus Tires in long Beach CA, (big time Lucas and Coker dealer) they really know what they are doing. I have bought a couple sets of wheels, including a custom order set, and several sets of tires there. I bet if you call them and ask, they will check the dates. They deal with timed out tires on collector cars all the time.
I'm gonna get the twelve 17" wide whites for my Imperials from them.
