Load Range E tire pressure: how do you keep them up?

[Whangler]

Soon, I will have my newer trailer, a 2014 Arctic Fox 25r. The first thing I do will be to take it to Discount Tire and remove the GYM's and put on LRE Maxxis 8008's.

My old trailer ran 14" LRC tires inflated to 50psi max. Even getting those up to pressure was sometimes difficult if I had to air up on the road using lousy gas station air. They held pressure very well, but once or twice I needed to bring them up a few lbs.

Now, these new LRE's run at 80psi. I reckon truck stop compressors will do the job but like gas stations, they're not always easily accessible. Do any of y'all use 12v tankless compressors when you're afield? If so, I'd like a recommendation for a good one. IF, that is you think it necessary.

Thanks,
Mars

I bought a cheapo 120v 2 gallon compressor off Jeff's website. It's not very big and has a lot higher CFM than any of the 12v units that were in my price range (under $100). It rides in a toolbox in the truck bed.

I fill my once a year. A few pounds over so they last for a year.
Never have to add inbetween.
Weigh your trailer then go by the tire chart for the correct amount.
80 may be too high.???
