I have a 74 260 which needs new tires and wheels. Original owner and I like the look and profile of the 185/70/14s, however alot of the new wheels in 14 are x7s. This would require going to a 60. How much wider is a 60 than a 70? If I go to a 7 wide wheel, should I go up to a 15. And if 15 should I go 195, 205???? I'm so confussed. OK, What looks and rides the best?
