I had the MB weighed today, the front axle is 4060#, the rear is 8500#. This is with full water tank, empty waste tanks, me in drivers seat, with a typical load out.
I'm running Cooper Discoverer HTP LT225/75/16 tires which have a max load of 2680# at 80psi max. I'm currently running 65psi in front and 75psi in the rears. I can't find a weight chart for these so wondering what air pressure should I be running.
Any suggestions?
Thanks!
Front axle is 4085# and the rear axle is 8660#. Running Michelin LT 225/75 R16 with 60 psi in the front and 70 psi in the rear. Btw, recommended tire pressure may depend on the tire manufacturer.

Hope this helps.
2000 MB
Condition: Fuel Fuel, full water, full propane, empty grey and black, driver plus 1 and gear for months on the road.
Tires: Firestone
Actual weighs: Front: 4440 lbs Rear: 8860 Weight fairly distributed left to right
Tire pressure at 59 degrees and sea level: Front: 61 PSI Rear: 69 PSI
Consulting the load charts, Fronts 65+ psi, Rear 70+.
Your LD Owners Manual should have the pressure/load chart.
When adding air, I set the tires 5-psi, over what the chart indicates, to allow for the gradual lose of air.
That way, air is only added a handful of times a year, using the TPMS to keep track of the actual pressure each day.

Thanks for the info. Looks like I may be able to lower the pressure a bit and maybe get a slightly softer ride.
BTW the propane tank is full also.
