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".
