Airing down. Where and when?

Hello.

So I run my 33x12.5x15 Maxxis Mudders at 30psi on road, and last time I went off road I dropped them to 20.

The minimum recommended for this tyre is 10psi, obviously people will drop Tyres lower at the risk of popping a bead.

My other concern is the more I air down the lower the axle sits, so I dig the diffs more.

As such, I'm curious, how do the rest of you get on with airing down?

I'm gonna give 14-15 psi a shout next weekend I think, but experience would be nice to hear!

I have lockers front and rear, so question is what's best: more grip and self cleaning or more axle height/tyre stability?

Cheers!

if you get some bead lockers go as low as you want, i wouldnt go any lower than 20 as chances are they will come off the rim

yeah i know about bead lockers, im just wondering if anyone else has experience of whether it's worth dropping lower, in case you lose too much ground clearance.

gonna look into bead locks eventually i guess, why not.

cheers
