I am currently running the Goodyear Power cushions on my 67' coupe with styled steel rims (14 x 5.5). No issues with the tires, but again, they are not radials and do not act or perform the same! Still, I show the car and they look period correct. Here is a pic, although not directly taken of the tires, but captured in the background during an engine build. I can get more pics if you like?
