I have a 2007 1500 Quad Cab 4X4 with the stock 20'' rims, I'm looking to go down to 17'' rims so I have more of a selection when it comes to tires, Looking to keep the diameter about the same at 33''. Any sugestions on wheel / tire combinations. Looking for a good AT tire, I do a fair amount of highway driving, but also take it off road a bit. I just don't want the noise of an MT. Thanks
