If you run 80psi in front on a light front end rig ( rear or mid engine) steering control will suffer greatly

X3 The data plate on your door jam was specific for your Conversion Van.

On my "B" with LR D tires I run 65# air pressure (Max allowed).
On my F250 (Load range E) when I pulled a 5th wheel I ran the Max on them also .
Normally on the empty F250 I run 50#.
Max air gives me more stability and control.

I have 2002 P W 80 rear 65 front makes it handle better.

To make things a little more simple. Your Class B should be 80 rear, and 65 front.

As per J-D's advice I too lowered my tire pressures.I was running 80 PSI and after weighing it and going by the Michelin pressure chart and J-D's advice I lowered the PSI, what a difference in the handling.I now run 55f/70r inthe tires on my E-450.You just can't go by what is stamped on the tire as many, including myself , did.WEIGH IT, WEIGH IT

Read the whole label on the tire, not just the big print. It's something like 'Max load xxxx lbs at 80 psi'. This is a major hint that correct inflation is weight-based.

Some upfitted vehicles take a bit more due to unusual vehicle dynamics, like my previous Roadtreks... 70 psi rear (IIRC) by weight, 50 front. But that didn't allow for the top-heaviness of a B. I ran 65 F & 80 R. No issues with good tires, other than squirrely Dodge handling.

Load as for travel, including passengers. Go to the scales. Look at the tire maker's inflation/load chart. Add some air in the rear if it drives better.

On our 2001 PW Excel on the Dodge chassis, I carried 80psi on the rear tires and usually 55-60psi on the front tires. We didn't carry full loads but always had lots of stuff so came close to the max weight rating. I used the info suppliied by PW on the door post rather than rely on opinions from different users. In over 20K of driving, some of which was on gravel and rough roads up in western BC, YK, and NT never had a problem with handling or tire wear.

My Airstream Interstate calls for 80lbs in both front and rear tires.
