I am chasing sway. Two years ago I bought a 2014 Ram 1500 4x4. Later we bought our first travel trailer which is 23 feet long. I upgraded shocks, bought Toyo Open Country ATs (replaced the factory Wanglers) and installed air springs. This weekend we went out and the truck feels stable but I feel too much tire sidewall flex. I like the truck and not likely to upgrade to 3/4 ton so I am looking for suggestions for tires that won't flex. I like the looks of the Toyos on the truck but comfort when towing is more important. A stiffer sidewall road tire is what I am thinking but not sure what.
