Wow, that’s a long time away! I’m sure you’re glad it’s back!

I had to put new tires on the Grand Prix. The older radials that were on it were starting to come apart.

I liked the thinner 5/8" white wall that it came with but due to the tire shortage and general status of 14" tires it was not meant to be. I was trading off size (P225/75R14 vs up one size vs down one size), white wall (and width) vs redline, availability and price.

After agonizing over my excel spreadsheets I made a decision and went with one size down (P215/75R14) and 1" white walls from Coker. Took about 4 months to get them through Summit Racing.

I wasn't so sure if I loved them at first, but upon further review I see that they are actually a bit more "authentic".

Before, after and vintage photos shown below.

I replaced the belted repo wide ovals on my '72 last summer. Hated to do it but felt that they were too old to trust anymore. Went Firestone radial repo's from Coker. They're raised white letter and look pretty close to what they were using back then. Going to be nice to drive on radials again.
