How do I put air in back tires?

[suscamper]

Newbie here. Need advice. Mushy ride and in Class A website everyone says you need 98-100 PSI tire pressure We only have 80!
So we are on maiden voyage in new RV and don't know how to fill tires!

Planning on stopping at a Flying J hoping there is room for our rig by air pumps

What type of extender do we need to get the back tires filled?
Do we have to purchase at camping supply or auto parts place before we go to service station?
Is there something else we should be doing?
Thanks in advance

Any auto parts store should have what you need. I'm sure they'll be able to help once they see your setup. So how do you know it only 80 psi? If you can check air pressure with a tire gage, you can fill at a station.

We used tire gauge from car to check front ones. Can't get to back tires to check

Stop in at Discount Tire. They check and fill tires for free. Watch what they do to fill the rear tires.
