Hi all I just joined and did a lot of searching and couldn't find a post about this. I just bought an 04 1500 quad cab ram with the 4.7 in it. I have 2 questions it has the 17" rims on it can I run 285s on it or what's the biggest? Second question while cruising along in overdrive at steady low throttle it bucks occasionally. Any info is greatly awaited. Thanx guys!!
