gas station air pumps

Carry one with you.

Go to a "truck stop" to buy your fuel and air up, or, go to the truck lane in the gas stations where you fuel up. Generally, you'll find that the compressors used for auto applications are for just that. Autos. They lack the compressed air storage capacity to fill larger higher volume/pressure tires found on trucks. Or, buy your own compressor so you can fill elsewhere at your convenience.

Battery operated Ryobi air pump before every travel day keeps my tires aired up. Recharge via TV’s 110 plug. So many gas station pumps are broken, blocked etc.
