Goodyear Tires

I believe that Chevrolet did NOT use the Polyglas tire in 1969 because of speed rating issues. The Corvette did not use it because of it. Rowdyrat knows more about this topic...BKH

I tend to agree. I don't recall a Polyglas on any '69 Camaros or Chevelles. The Goodyears were Wide Tread GTs.
Didn't the '70 Corvettes with Goodyears have a 'Speedway GT' or the like? I bought a full set; tires and wheels off a '70 when the owner replaced them with Ansen Sprints and M/T tires. Seems like I remember the word Speedway on them. Still have the wheels but the tires are long gone.

BKH I can't comment on the speed rating, However to add to this topic most the original 69 tires I've see, sold or owned over the years are all Nylon cord or a similar compound. I believe the "Glas" in PolyGlas is a reinforcement agent in the compound for a technologically advanced tire that came along as the replacement stock tire for 69 and earlier camaros.

I don't recall ever seeing Polyglas tires on '69 Chevelles and Camaros either. The car we bought new had the PL5 white lettered Uniroyals. My buddy's car came with white lettered Firestones. Our SS396 car came with option PW7 white wall tires. GM documentation doesn't show the brand. The Polyglas tires were top of the line back then. They would have made a nice option. My Uniroyals were woefully lacking in traction.

I recall reading that the Chevrolet engineers didn't trust or had concerns about the "new" Polyglas technology being up to the task on the Corvettes and musclecars. Thus it seems that Buick/Olds/Pontiac all started using the tires prior to Chevrolet. Last time we debated this, I scoured all of my old magazines, looking for pictures of '69 Chevrolets fitted with Polyglas tires. I didn't find one. The earliest Chevy I could find pictured with Polyglas tires was the '70 LS6 prototype/press car shown at the '70 new car introduction. That would have been assembled in mid-to-late '69 to make the September or October '69 issue of CARS magazine.

I did find a picture in Marty Schorr's "CHEVROLET The Performance Years" of a Troy, MI based '69 Camaro ID'd as a COPO wearing what appeared to be 14x7" Rally Wheels and f-70-14 Wide Tread's(not GT's).

O.K. so what are the correct tires for a Chevelle or Camaro ?

And when did they change to DOT from a non-DOT tire.
