I had a set of 165SR15, a set of 26x15 M/T ET Street fronts and a set of Moroso 7.10x15 on different sets of wheels.(for my 1071 duster) I ran the 165SR15 on my 1969 Dart GTS with the original K member and torsion bars The Moroso tires would rub real bad on a sharp turn with the front end lowered down so the LCA rubber bumper was about a 1/2 inch above its bumper on my Duster I raised it up to the stock front end specs. later and that help on the tires rubbing on the Hedman fenderwell race headers, they had rubbed worst on the Hooker 2.0 inch fenderwell headers in the Duster
