Speed Racer Posted November 8, 2011 Share I weigh 95k's and run 18 - 23 psi front and 20 -25psi rear depending on the trail. Road go as hard as the tyre will allow.Is this tubeless?

Speed Racer Posted November 8, 2011 Share Yep, since moving to tubeless I've dropped pressure to 20psi front / 28psi rear (I weigh 69kg), it's amazing how much extra grip and control magically appeared.What tubeless set up are you running?

tombeej Posted November 8, 2011 Share Is this tubeless? For sure it would be. Going low pressure with tubed tyres will just end in tears. From personal experience, when I moved from tubed to tubeless my average speed increased instantly. Of course it was also combined with a change in tyre choice from 2.1 to 2.25. Running low pressure on wide tubeless tyres has to be experienced to be really appreciated. It made such a difference to my riding that I now have a sense of what it must be like to ride on EPO for the first time . Not to mention that flats are virtually a thing of the past.  The only fear now is a large sidewall tear. But I always carry a spare tube and old piece of cut-out sidewall for that eventuality.

scotty Posted November 8, 2011 Share I run tubed at 2.5 front and 2.8 rear on my 26" for most MTB races (max pressure indicated on tire 4.5)Â I find its a balance between traction which less will give you and greater puncture resistance which more will give you.

Iwan Kemp Posted November 8, 2011 Share I find its a balance between traction which less will give you and greater puncture resistance which more will give you. Relative. Higher pressure will result in "stiffer" casing which in turn could make it easier for the thorn, glass or whatever to penetrate and puncture the tire. Chances are if it's run at lower pressure to tire will deform or "give" quite a bit before giving way.

Cycling Major Posted November 8, 2011 Share Hey Guys I've been riding with Conti Gatorskins for quite a while now... Brilliant tires and never gets punctured. I have always run them at 8.5 bar (Conti MAX recommended), but this morning I heard a few guys saying that you can pump them alot harder... What do you guys ride them at? and what would you say is the best "bar" to go fastest but also minimize a puncture? Thanx in advance Edited November 8, 2011 by Cycling Major Link to comment https://forum.bikehub.co.za/topic/109765-the-mtb-tyre-pressure-thread/page/2/#findComment-1526650 Share on other sites More sharing options...

( its not like going from 2bar , you already damb hard ) Link to comment https://forum.bikehub.co.za/topic/109765-the-mtb-tyre-pressure-thread/page/2/#findComment-1526657 Share on other sites More sharing options...

Chances are if it's run at lower pressure to tire will deform or "give" quite a bit before giving way.Its mainly for pinch flats i'm concerned about. Striking a rock at low pressure will increase the chance. I also use slime tubes and tire liners, overkill perhaps but in my 5/6 years MTB i have only had 1 puncture and that was when i replaced my tire without fitting the liner.

Tiny K Posted November 8, 2011 Share Well I guess how dead you want the gator to be and how intact you want the skin to be.... I would moer it with about 9 bars..... but then I have a real bicycle tyre, Schwalbe Ultremo ZX, that can go to 10 bar.
