Tire pressures and my air compressor
Ok, so granted I am not the heaviest brick in the load so thought I'd ask this question. It might be simple logic but I want to be sure. My RV tires are to be at 130PSI front and 120PSI rear. My ai...

I would get that Newmar weighed and then check the tire manufactures site for the proper air pressure for the weight. Never fill to max pressure on tire sidewall, it will ride like a brick and will wear the center of the tires down in no time.
The maximum pressure listed on the sidewall is for loading at the rated load for the tire, First thing is to weigh the coach, full of fuel, water, propane and all your 'stuff' on board and then determine gross weight and adjust tire pressures accordingly.
I disagree with your premise that the center of the tire will wear down in no time or the unit will ride like a brick. Tires are designed to run at maximum listed sidewall pressure and tires provide very little compliance (flex) when rolling. The suspension provides ride compliance (comfort) not the tires. Tires are designed to carry a load with minimal flex (which causes internal heat), not provide a comfortable ride.
