I am currently running 245/60/15s on the back of my 67. I am trying to figure out what size i should run on the front. Right now i have 235/60/15s on the front but they scrub when i hit bumps. So i was thinking 225/60/15s... which are a 25.60 inch tire. The 245/60/15s in the back are a 26.60 inch tire. Im thinking an inch difference between back diameter and front diameter might be to much. What do you guys think? The other option i was considering was 215/65/15s in the front which are a 26 inch diamter. That sounds right but i really wanted to go with a fatter tire than 215. Any of you who are running 245/60/15s in the back what size tire do you have in the front?
