I need some help. With all the offroading I've done, I've never aired down my tires. Usually because I had no way to air them back up. I also didn't know how low to take them for any given terrain.

The terrain is almost always dry, loose rocks (about the size of softballs) with embedded sharper rocks.

So I could use some advise. How do you guys air backup? Tank or pump? How low should I be going?

Im using brand new 10 ply E rated General Grabber At2's. 245/75/16.

 

i'm using my sliders as tanks for air up. wanting to get a new on board compressor. mine died
