Hi I have a 2000 4700 and 2004 Prowler Reagl AX6
When I bought truck used, with 2 people a full fuel 120gals.Wt. was
Solo: Front Axel 7620 Rear Axel 5720
GAWR: Front Axel 10,000 Rear Axel 15,000 Air bags 17,500
Loaded whith 2 people/dog :P /electric scooter(no back seat) full storage bay
and 3 storage boxes on bed.
Solo: Front Axel 7900 Rear Axel 6640
With 5er Front Axel 8200 Rear Axel 9700
5ER Axels 13,000 (GAWR 4,000lbs. each) (Spring Rating 4,000each)
Now for tire pressure for Michelin 245x70x19.5
The minimum tire pressure stated by Michelin Costomer Service 75lbs. for all tires Front or Rear
A front axel load of 7,900lbs air pressure 95lbs. which has a load carry of
8,200lbs. a 300lb reserve for load transfer due to braking
A rear axel load of 6,640lbs air pressure 75lbs. which has a load carry of 12,840lbs in dual setup on rear
So in my truck I can run air at the same pressure loaded or unloaded
