Hello
I need some help - I want to keep my 1983 Buick Riviera 100% factory and that includes the look of the tires. Well, I know I can't get Royal Seal white wall tires anymore, I'm looking to find out the exact white wall width of the factory tires on the 1983 Riviera. This is not a T-type car, it is the 307 V8. Maybe someone out there by chance has a low mile original Riviera with the original tires that they could throw a ruler against? I would be eternally in your debt.
Thank you!
