Thread: IM undecided on tyre pressures for slippry mud surfaces etc

Personal preference at the end of the day plus how you drive and on what terrain. To give you an idea, I have run 2 sets of 32" BFG muds on my D2 at 38psi all round on road (as you said, seemed to be the best for grip and comfort). I ran them at 18psi when off road for rock, mud and basically everything but sand (around 16 for sand). Again this seemed to be a good pressure for most of the stuff I was doing and would allow the side walls to bag nicely.

I now run 33" Silvertone Mt117 Sports and run these at 34psi all round on road and generally at 15psi off road. They have a much firmer construction over the bfg's and at 18 psi off road did not bag quite enough to get good grip on rocks etc. I would suggest for mud though IMHO it depends what kind of mud Sometimes you need to get through the top layer to the hard ground underneath so perhaps slightly higher pressure but sometimes if it is think deep mud, you need as big a contact surface as possible so perhaps lower pressures.....that's just my observations and views however I'm sure someone with a bit more experience can help you more.....and may blow my theory out of the mud bog as well

Aye, Mick

P.S. A good tip though is to set your tyres to what ever pressure you think you need and get someone else to drive your car through selected terrain......look at what is happening to the tyres etc as this is a great way to get a visual on what happens at different tyres pressures. And should go wothout saying, lower tyre pressure means lower your speed in every circumstance.

16-22psi is a good sort of range, start from the upper range as two low a pressure can be a problem as well.

Good advice there. Plus, it's also easier to lose air than re-inflate if you've taken too much out.

^^^^^its all their, nothing to add
