Theo18 Posted May 4, 2011 Share Hi there How do I know what the correct tyre pressure will be for my mountainbike? I obviously have to take my weight into account but suppose that the type of terrain will also play a big role.Currently riding mostly in the Western Cape, jeep track & single track. What pressure do you guys riding here inflate your tyres to? Micahel 1 Link to comment Share on other sites More sharing options...
banna Posted May 4, 2011 Share I run tubeless tires and the following pressures:Front 2 barRear 2.6 bar I weigh around 90kg. Obviously if you weigh less you can go lower than what I've indicated. The nice thing about tubeless tires is that they have stronger sidewalls, so you in general you can run lower pressures and thus have more grip.

I'd say 1.8 - 2.0 bar megdobson, Nick G, Stoffies1 and 8 others 11 Link to comment Share on other sites More sharing options...
MissionMan Posted May 4, 2011 Share I ride 2 infront and same or just below rear ... rear can be run lower because the front can burp if too low... majestic 1 Link to comment Share on other sites More sharing options...
Zula Posted May 4, 2011 Share You probably cycle on tar with that pressure?? I'd say 1.8 - 2.0 bar Agreed! Recently dropped my rear pressure to 1.8 and the front to 1.6.

banna Posted May 4, 2011 Share Agreed! Recently dropped my rear pressure to 1.8 and the front to 1.6. Its made a massive difference! Hmmm... on 2 occasions I've run the tire completely off the rim with pressure being too low. Since then I've been hesitent riding too low pressure. I also weigh 90kg and not 65kg like the race whippets... TheBikeShackZA 1 Link to comment Share on other sites More sharing options...

Tumbleweed Posted May 5, 2011 Share I'm 65kg and run my tyres between 2 and 2.5bar mostly. Hate the feeling a "dragging" tyre. Greybeard, Mrs Balls, Matchstix and 2 others 5 Link to comment Share on other sites More sharing options...

IdeJongh Posted May 5, 2011 Share 78kg and run 2bliss with 1.8 rear 1.7 front and works well across most surfaces. Above 2bar they start feeling less grippy and below 1.6 too floppy.

CAAD4 Posted May 5, 2011 Share Just don't make the mistake that some riders make of running their pressures too low after they have done a tubeless conversion using standard tyres. Those sidewalls are not designed to run very low pressures and you are bound to end up with your tyre running next to you and seeing views of certain body parts that you are not familiar with. linuxlg, optics and Mongoose001 3 Link to comment Share on other sites More sharing options...
Mojoman Posted May 5, 2011 Share I'm 65kg and run my tyres between 2 and 2.5bar mostly. Hate the feeling a "dragging" tyre.For sure, I am around 105kg and run at about 2.8-3 bar on Crossmarx. JWF 1 Link to comment Share on other sites More sharing options...
