They are "Champiro 75" it's a GT tire. They fit very nice on my 79 Seville..Nice wide whites and brand new. I've been looking for a tires for this car and my other carsfor a long time..It's been hard to a bigger w/w. Firestone had some but discontinued them and before that(A long time before) I was buying goodyear double eagles. Yes the Vogue Tires are nice but hard to get and you will not find them cheep. These tire from tire factory are $52.50 each carry out in Washington State. (as of today) I put them on my 77 and my 79 Sevilles.
Treadwear is 460. These tires will dry out and crack before I can wear them out. Check out the pictures.
