I have Draglites on my 67 , I did have to buy one new 15 x 6 that I had on the front because it was manf. out of round, I didnt know this until the second trip to the tire shop where it was discovered. I spent some $$$ looking for a vibration on a new driveshaft and I even switched my 4/11 that I never cared for to 3/55's
