Can the air compressor (in the back) inflate your tires?

[NEGATE]

In the older H2's there was a valve stem right by the compressor on off rocker switch. You hook the hose up there and the other end would thread onto the valve stem on the tire. Did you check the owners manual?

YES, that's what it is for to reinflate your tires after you air down offroad. If you go down to around 8 psi, to bring them back up to 37 psi takes about 5 minutes each tire (been there done that many times), so give yourself lots of time.
I carry two bottles of Hutchison's fast air bomb and seal under the back seat for when I want to do more than one tire at the same time and get out of Dodge! One bottle will do a stock H2 tire from 8 to 37psi in about 40 seconds.

you air your tires down to 8psi? I hope with beadlocks...or did you mean 18psi?

[HummerJim]

Yep 18 psi. I would NEVER go below 15 psi with a stock tire offroading. I really haven't noticed a lot of difference between 15 and 18, so I just stick with 18.

thanks for all the replies.
I figured it out w/everyone's help.
I didn't realized the adaptor was inside the bag.

Thanks.
