send me your e mail address and I will send you a article compiled by schwable on tyre pressure and rolling resistance on various surfaces

Knowing your weight would be usefull..

I'm 78 kg's ride with tubes / Schwable Racing Ralph's and pomp my tyres on avg to the 38psi thingy on my pump.

I ride the MK 2.2" UST. I weigh 100kg and ride a dual suss. I pump mine to 2.0 front and 2.2 rear.

 

Personal preference should influence your final decision.

Wow about 30 psi, thats the advantage of running tubeless

78kg and i run my mk's at 2.2bar

Whatever is comfortable, gives good grip, prevents pinch punctures, tyre pressure is a balancing act. depends on your weight, tyre volume, shock setup, riding style etc.... Just start with a fairly high pressure and reduce it bit by bit until you reach that happy medium

My mass is 74kg and I run 25psi on tubeless - perfect! I see from an article by Sauser that he runs 28psi. Tubeless allows you to run much lower pressure, giving you lots of grip over rocks, etc.

The Scwalbe article is wortwhile reviewing and supports such low pressures.

I weigh 90k's and pump my UST Kendas to 22psi front and 25psi rear

Good read.

[Karl Beaton]

thx for the info ... i have tried at 2 bar and it seems much better

[crasher]

Wow thats an interesting read

When I got my new bike with tubeless it was set at 2.2 front 2.4 rear and it felt horrible!

I was running 4 bar in my hardtail with tubes which is prob why it felt so horrible to what I was used to

With the tube less I have been running 3 on the front and 3.4 on the rear and have been happy with this but I will definately drop the pressures down and give it a try but dont know if I will get to 2.2 but even half a bar per wheel drop would be a nice advantage as per the article

thanks good thread and read

I do between 1.7 and 2 bar for 1.9's to 2.1's.

I'm 68kg.

 

Never over 2 bar for any tyre for me.

Just a tip.

 

With tubeless and such high pressures, you not only lose grip, but the tyre is prone to cuts when it's so hard. Bigger puncture holes also take more time to seal with such high pressure behind the hole - normally some sealant is sprayed out as a mist before it seals when the pressure is lower.
