Off road tyre pressures?

[nadeem]

Just fitted TKC 80's this morning, the garage inflated them to 36psi rear & 34psi front, any idea what they should be for off road use...?

Generally 25 psi front and rear seems to work ok on rocky terrain. Any less and you risk dinging a rim, I'm sure you know how expensive damage to wheels can be

If you're doing a lot of mud, higher pressures might actually work better, as rather than deforming the tyre stays rigid and the knobbles 'punch' through the mud to get grip.

For road use I use 28 / 35.

...if the TKCs on the rear are tubed & no security bolts, beware of too low pressure leading to tyre creep, pulling the valve out of the tube. Best to leave the locking nut on the valve loose so as to enable checking this.

both tyres are tubeless....

and airless, after hitting a kerb

you will have noticed my sudden interest in places without any kerbs...

I use 4 psi for mud and 6psi for rocks, in my tubeless rear tyre - no rim locks obviously and works fine...................gives a nice flat 'footprint' for maximum grip................. however it's on my Montesa 315R Trials bike

I use 4 psi for mud and 6psi for rocks,

what would you suggest for kerbs

 

[nadeem]

I tried them on the Off Road course in Wales and they were pretty good, brill off road and good enough on road - bit noisier than the tourances though...I'll keep 'em on till next month, when I'm going on one of Paul Devall's Blockhouse Runs to Bruges...

 

[JohnnyBoxer]

what would you suggest for kerbs

Definitely 6..................bloody heavy these GS's

I doubt we'll be doing anbything tommorrow that'll be worth lowering them Nadeem....maybe by a few PSI for the mud but I don't bother
