IMO, one of the significant STANDARD components of the Road Runner "Spring Special Packages" was the introduction of F70-14 Goodyear Polyglas tires w/RAISED WHITE LETTERS. "Red stripe" Polyglas tires were a no-cost OPTION with the A14/A15 RR packages and were spec'd on about 1/3 of the cars.

..... but a red car w/white stripes & top definitely needs RWL Polyglas tires!!
