Just purchased 2002 Workhorse P30; front airbag question

P57GX I put in 75 PSI in the bags. It is about 1/4 inch off the 2", but we'll see. The flat airbag is holding for now. I'll measure it tomorrow. I might be able to live with a slow leak for a while until I can get a handle on what I need to do.

What do you like instead of Michelins? The PO said the shocks were a year old, and the front tires were 2 years old. Must have noticed the cupping!
