Two years ago I put Firestone 721 radials on my Cordoba, which is based on the same platform and is roughly the same size as the Imperial. I believe the whitewall width is 1-5/8", and they look fabulous on the car. I also stepped up a size to 225/75R15, and have had no trouble at all with scraping of the fenders or anything like that. They seem to ride smoother than the old Sears/Michelins I had, that only had about 7/8" whitewall.

I checked the 1 5/8ths dimension out, and it seemed like it would be too wide to match the original style. I then did some detective work. I measured the width of the cornering lamp on my car. Then I looked in the 81 brochure at the side view printed there. Using the cornering lamp and tire I figured that proportionally it works out to a 1 3/16 inch wide whitewall. I think that would look correct. The Goodyears on my 83 now have a 3/4 inch wide stripe and it is definitely to narrow. So, anyone know of a tire that has 1 3/16??
