I just towed for the first time with the new E-Rated Nitto Terra Grapplers. Previous towing has been with the Michelin stock P rated tires. I have air bags also at 20 pounds.

55 psi in the rear, 45 psi in the front. Trailer listed dry weight is approx. 7500 pounds and I add about 1000 pounds at the max to the trailer, and no water in the holding tanks. Hitch weight is listed at 1,540 and only my wife and I in the truck with 3 little dogs at 15 pounds each.

The truck definitely handles the bumps much better over bridges. Side to side movement seems to be an issue, and the combined package seems to be more sensitive to the crosswinds compared to the P rated tires. I like the feeling of the P-rated tires better besides the bumps.

Do you think I have too much air in the tires? Will a sway bar help drastically? I don't want to lower the air pressure too much with the weight I'm pulling, and I know other guys are pulling with more air than me. Maybe 40 in the front and 45 in the rear. Let me know what you think.
