I want your guy's opinions. I going to be needing some new tires soon. I'm thinking of the Nitto 420v or the Nitto terra grappler g3. I don't tow and no heavy loads. 99.9% of the time I am on city streets. My current tire is LT265/60r20, 3195lbs @80psi. The 420v size I am looking at is 275/60R20...
