Trucks, Freightliner, Volvo, Kenworth, etc, normally have air system set @120psi or so.
I've found the highest I can inflate the tires using the truck air system & a 50' hose is 97-98psi.
Need a bit more. Looking for 115psi on the steers(cold) & 105psi on the drives.
Was wondering if an air powered booster pump would be possible?
Say, 50% of the airstream as high-pressure supply, and the rest to drive the booster?
If not practical, any easier/better way?
thanks
