Planning a trip on gravel this weekend. Still have road tyres on.
What is the recommended tyre pressure for dirt?

I think this is a question with many answers..... Gravel road (hard gravel/gravel "highway") I ride 2.5bar don't bother to deflate. If I run into a bit of the loose stuff I'll drop to 2.2 or 2.0 bar and the same goes for sand.

Unless you gonna ride in serious thick sand I wouldn't bother going under 2.0 bar. But if you take one of those fancy mini-compressors with on your trip, then I suppose you have a whole lot of options.

That said.....this is what works best for me

Yes  :thumleft:

Also take note that the Warning light for flat tyres will come on. That irritated me like crazy, so when I deflated, I always kept it just above that so the warning lights cant flash all the time.

You can set the bike to not warn you about any low pressures, while the riding mode is set to Enduro or Enduro Pro. Check your manual... very handy feature! But, as soon as you go back to Rain/Road/Dyna mode it warns you again.

Edit: As this is posted in the LC section I assume you are referring to the GSA LC? If not (older GSA) then my statement above does not apply.

from this past GS Trophy, I know of two guys damaging rims on gravel roads with their tyre pressures just below 2bar. One of them happened in front of me. Could not believe how the LC rim was damaged by the rock that the guy hit. My bike ran well across all the rocks. I was running Karoo 3 front (2.2bar) and Anakee 3 rear (2.4 bar)

Maybe its not worth it. Run the tyres a bit harder unless its really needed to drop the pressure and then ride carefully. Slow down a bit and avoid those rocks.
