Right now my Aria 3701 tires are inflated to 120 PSI. It hits the bumps very hard. I'm going to weigh the rig this week and follow the Chart that Michelin put out.

My tire pressure monitor system shows the tires getting up to 132 PSI going down the road. I'm hoping to reduce the pressure by at least 10 PSI to soften the ride. I will post the results in the coming weeks. Any other input is appreciated.
