I just bought a new 1320. It has 275s all around. I have gone ahead and taken the drag radials off for now and put on some Continental Extreme Contacts. Those of you who run 275s how are you doing on rock chips down the sides of the car? I know the wide bodies have had a problem with rock chips but the 1320 is not a wide body. I had ZL1 rock guards on my Camaro SS. Without them those cars got ate up in front of the rear wheels . I didn’t have a problem with chipping on my other Challengers that ran 245s. I don’t want to put the rock guards on the 1320 unless they are really going to be necessary. Thoughts?
