I'm sure there was a thread on this but I can't seem to find it.

Can we use the air compressor connection under the front hood to add air to the motorhome's tires?

As long as the gauge is reading over 100 psi (engine should be running, I'd assume), then we should be able to add air to the tires using the motorhome's own air tanks?

Thanks.

Yup, you sure can. As you assumed, the engine must be running to keep supplying air.

Thanks, Rick!

So as long as the gauge is reading over 100 psi, we should be able to "top off" the air in the tires to over 100 psi (if so desired), correct?

One of the great advantages of having air brakes - you get a large built-in air compressor!

Only problem, my front tires require 120lbs and the coach air will not pump that much. Max I could get is 115lbs.

Thanks Rick and John!

Wow, Gary, you put 120 lbs in you front tires? I think they told us that the maximum we should put in ours is 110 pounds. If that's the case, the coach air should do the trick for us, correct? Thanks!

Unless you are at the gross weight for the front axle, you don't need to run the max pressure for the tire.

Yes, I am going by the Winnebago recomendation.
I have tried lower presures and the ride seems to be worse, best ride and handling is at the max pressure.

Not only can you use the coach air to fill tires many times on the road it is the only option. Most gas station compressors do not go over 90 lbs and most of our rigs require more than 90 lbs in the front.

1st time I tried to add air on the road the tire actually put air in the compressor tank, I needed 95 lbs and after trying to add to a tire with 92 lbs the pressure in the tire went down not up.

"Top Off" is a good two words. The air compressor is high pressure, but may not be high volume. If the tires are really low, plan on taking some time to get them full.

I vote with John. 120 lbs is a lot of pressure in the tire..I would check the manufacturers pressure guide for correct inflation for your weight..To each is own, but I hope the tire doesn't let go with that much pressure or have a good supply of toilet paper...

The 120 lbs is listed by Winnebago and is on the tire. If it blows toilet paper will not do much. We went out this weekend at a lower pressure and we can feel the bumps more than at maximun pressure.
