Speaking of which - I have been meaning to share with the team that 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".

----Having had my 64 421 HO 4spd GP I agree with you. When I bought mine in Washington state it literally had white letter Grand Prix after market tires. I drove it all the way back to Massachusetts, but made a stop in Chicago and got correct Coker Firestone white walls from some guy there. I couldn't make it home without putting correct tires on it!.....Bill S

Oops....an obvious misspeak on my part! I was thinking in Chevy terms! No disrespect to our Poncho friends!!

But red stripes on a '63 SWC is still wrong!

Keith, excellent tire choice, the GP looks great!!

I can't speak for radials, but in bias ply, I've observed Coker casting multiple size designations into a single dimension tire, which can result in a larger than original dimension tire
A few months ago I was in need of a set of 7.75x14 blackwalls, which Coker doesn't offer. They do offer 8.25x14 in black, the dimensions are exactly the same as 7.75 white! Not the first time I've seen this.
