low profile tires on duster

Sorry no pics but I have a 74 duster with 215/60/15 with 15x8 rims all around and it looks funny in the rear because their is too much wheel well showing so in fact just today I went to the local tire dealer and I am going to 255/60/15 with 15x8 rim in rear and 215/65/15 with 15x7 rim up front. BFGoodrich T/A tires and Crager rims. I like the idea of the tire absorbing some of that pot hole and helping the shock instead of beating the suspension. Good luck on your choice !
