I loved black on my white LMM. It was so easy to keep clean and looked good. That being said if you are keeping the chrome (no color match) I think that chrome and white with clear lights etc looks clean too.
I had 305/50/20 terra grapplers on my truck last summer. The tires weren't the greatest of shape. However they seemed to wear extremely fast on a 3 hour driving pulling a trailer with a jeep on it. It actually cupped on of the rear tires really bad. Any suggestions why? Not enough air? Tires were shot? Question is buy another set of them or go with something different?
