The original tires on the 1972 Hurst/Olds were Goodyear Polysteel G60-14s. Good luck in finding a set of those.

So, is this ‘66 a radio delete car?

No . . . it's a no radio ordered 66 :smirk:

There was a 1972 HO Festival convertible on BaT recently with its original Polysteel spare. I believe the only cars to ever have these were the 1972 HO's. The only time I ever see these is as a spare in a 1972 HO.
