Wow, what a find. I looked all over for that size and couldn't find them any more.
Jeff's advice is no doubt sound, and I may give in one day, but I'm trying to keep mine mostly Origional including these tiny wheels. I do think I might give in before paying $800 for 4 Coker tires however. My tires are 185 70r13....and they are a nice tire and in great shape but small. 23.2" in diameter. (According to http://tire-size-conversion.com/tire-size-comparison/ )
My spare was trash, so I bought a spare that is a 165 80r13 and had it put on after the wheels were painted. It's 23.4" diameter. 0.2" bigger, and I can tell the difference in the look. The coker bf Goodrich bias ply are 23.78". I think I'd rather go the quarter inch bigger...and do 175 80r13.
Dennis, I think you found the perfect last set of tires for our cars! I think I might buy a set after I get rolling again...maybe next spring.
