Tire pressure

I always keep all tires at the pressure shown on the sidewall whether I'm loaded or not. Both the Truck and trailer are at the pressure shown on the sidewall. Door jam label is based upon the original equipment tires.

Many RVers use the pressure charts shown on the tire manufacturer websites and adjust the pressure based on load according to the chart.

I don't have that kind of time to be fooling around with adjustments.

X2. If I maintain my TT's tires at the max. inflation pressure I never have to worry if the tire's full load capacity is available to me, not to mention the heat generated by the rolling resistance of the tires won't be increased by an under inflated condition.

Some will say...weight your rig each trip, weigh each axle, weigh each corner or tire, weigh this, weigh that...Check pressure at every stop, check temp at every stop. Adjust pressure for altitude...

All this weighing is WAY to complicated for me. I like to keep it simple. Inflate to the max as stated on the side wall and get on down the road.

I agree with the above post from downtheroad. All of that paranoia is a waste of time. Proper tire maintenance, plus knowing what the actual weighed weight of the RV is (once) and staying close to that is good enough.

I inflate the TT tires to the sidewall pressure and am done with it. In my case that means 50 psi. if it is a couple psi over I leave it alone - this is not rocket science. Under inflation leads to heat and failure so why bother with lower pressures? The tires are rated for their sidewall pressures and given you are below the rated load and speed on the tires you are fine.

On the truck I use 2 pressures - a little over the pressure on the door jamb (30 psi) when not towing, i.e. 35 psi because I like how it feels / handles at that pressure and I get better mileage. I also used that pressure when I had my hybrid, but after one short trip with 35 psi and some squirm while pulling my new trailer (below) I upped the truck's rear tire pressures to 40 psi (max is 44psi) and pulled 750 miles from GA to Houston perfectly. This on P-rated tires. I have been driving around town with the 35/40 pressures and it feels just fine, so I will stay with that setup from now on.

ST tires perform best at max psi stated on sidewall so we keep them at max, LT tires on our truck are set to max psi on the rear axle and about 15# less for the front axle tires.
