Steering on class A

[JayGee]

On my 2005 P32 chassis I ran the airbags at 95 and the 225-19.5 XRV tires at 85 to provide me best driving experience. My front end weight was just under the 6000 if I remember correctly.
I have since replaced the airbags and old springs with new springs (no bags) to give me a little better ride height, and also new tires so a few things are different now.

Thanks for the air bag info Gary.

The new ones are rated at 85lbs max and the dealer told me to put in 80lbs all around.

Unless the dealer weighed all 4 corners of your RV and compared the weights to the manufacturer inflation tables... then he is just spitting out numbers without any facts.  In other words, you need to do what he didn't.  Get your rig weighed and obtain (generally available by download) a tire inflation table for the make/model tires you purchased.  Also what size are they?  If you have LT 16" tires like mine and many other rigs of our vintage, they will probably need to be run at close to maximum inflation.  But you won't know for sure until you weigh the rig... at LEAST front and rear axle if you're not able to do all 4 corners independently.  Trucks stops or gravel pit truck scales work best.
