NEW Dodge 2013 Ram 3500 4x4 -> ride is horrible! What to do?

Hey Guys: Why not look at the simplist possible solution, the aggressive nature of the tires. My Ford F350 came with what looked like winter tires with fairly aggressive treads. I switched them out for much smother riding highway tires. I do not plan to take my 4X4 off road as I use it to tow my 38 ft Montana 5er. Just an idea. Golferdave
