How much PSI for sand or mud?

How much PSI or Bar do you use for sand and how much for mud?

Depends... does it have rocks?

OK because no one else has chimed in.

I think I was running 12 psi in the back.

This is only my own opinion I suggest you go and ask riders in your area our a reputable dealer/club in your area.

But as Crazy said depends if you are throwing rocks into the equation and what tyres and tubes you are using.

Because I was riding trials for the last couple of years I don't fully remember.

i was running 4/5 psi in my trials tyres.
