Airing Up Tires with Onboard Air Compressor
I'm getting frustrated that I can't air my front tires up (need 125 psi in my 315 tires) using the onboard air compressor? My air system tops out at about 110 psi. I can air up back tires just fine, since they are in the 85-95 psi range. And it seems that every Flying J or Pilot I fuel up at, the service air pressure only runs about 110 psi!
Can anyone recommend a good portable AC that will handle larger tires?

Yep, you just want a pancake comp that will do 150psi. Lots to choose from at HD/ Lowes, Sears.

I purchased a Viair compressor. No worries of overheating.

I vote for an air doubler from SMC... I have mine mounted on the wall next to the basement thermostat and the hose reel in front of it. 50 foot reel reaches around the back to cover both the tag and drive wheels on the driver’s side and then around the front for the driver’s steer tire. No pump or motor to run out or break, no noise and no fuss. Best mod I’ve done imo.

Just bought an SMC today. Looking forward to hooking it up.
I have tried the different methods to be able to use the onboard compressor, but they all took to long.

ViaAir 450RV small air compressor is hard to beat. I own one and it is able to handle everything on the coach and easier to store than a pancake (I have one of those for the house also but not for use onboard the coach).

Bob Dickman Tire Center in Junction City, Ore. has a multiplier that can be installed or used as a portable. Works very well with coach air system.

This little air doubler works like a charm. Small, easy to store or mount, fills the tires like a charm. Can be set for up to 200 psi.
....Sorry, can't seem to get the pic to attach

I installed the SMC air doubler as well. It works great and you fill the tires with filtered dry air from the coach's air system.

Marc it was your detailed post, and Magic-Carpet, Jeannie, that pointed me in the right direction. http://www.irv2.com/forums/f278/infl...ml#post2917459
Thank you both for sharing, it was really appreciated on my end.

SMC is selling their air doubler for $438.00. Is that the going price or did you find a better deal somewhere else?
Our coach tops out at 125 psi and I run 112 psi in the fronts so I am OK with the on-board Cummins-powered compressor, BUT, if I could get the capacity and pressure from the air doubler, at a fair price, I would buy one. Not at $438.00 though.
Thanks for further input
