Twitch-119 Posted January 22, 2010 Report Share Posted January 22, 2010 I have a Try-all Sticky White 26" on a Echo SL rim and I weigh roughly 62kg, just wondering what the stupidly low point of psi would be, and what's the average psi for you guys on 26" at the moment I'm on 16'ish psi? And that feels very good, but i can hear the rim 'twang' on some stuff? i know this is mostly personal preference but if there is a way of working it out better, then that will be appreciated very much.

treewizzard Posted January 22, 2010 Report Share Posted January 22, 2010 stupid low would be weird steering, constant pinch flats, and bent rims. from what ive heard psi is a personal thing and you should use a psi that you are comfortable with. i have normal mountain bike rims on my bike so i like to run a higher psi. i have still heard that twang sound from my bike and i dont really like it either, but i guess as long as i dont land/hit something too hard my rim is fine. if you feel like your hitting your rim too hard then you can always up your psi. you should listen to what some other people say too before you listen to me, as i am not yet a bike magician. -steven Quote Link to comment Share on other sites More sharing options...
Danny Metcalfe Posted January 23, 2010 Report Share Posted January 23, 2010 Same As Above, But Echo rims are quite wide so you should be able to run lower pressure with a reduced risk of tyre roll, It is personal preference, I don't like my tyre too hard as they tend to bounce on rocks, so lower pressures roll more, and also i prefer them lower pressure, as I find it helps with preloading.

Muel Posted January 23, 2010 Report Share Posted January 23, 2010 I find having a higher pressure helps with preloading, otherwise it just rims as soon as you compress. I think I run about 25psi in the rear, I'm around 79kg. Quote Link to comment Share on other sites More sharing options...
cai Posted January 23, 2010 Report Share Posted January 23, 2010 I'm 85Kg, and on my stock (I too have a Try-all sticky's, but not the 'Barbie' couloured ones ) and I run 20PSI front and back. Seems like a good preasure to avoid dents in the rim, and punctures - but it still keeps the bounce in the tyre. Quote Link to comment Share on other sites More sharing options...
Twitch-119 Posted January 23, 2010 Author Report Share Posted January 23, 2010 Cheers guys, i thought it was quite personal, but always wanted to ask just incase... And as for the 'barbie' comment, thats is insane! I'm calling my bike Barbie! from now on i ride Barbie! ha who else can say that, part from ken!? thank you Quote Link to comment Share on other sites More sharing options...
Jake. Posted January 24, 2010 Report Share Posted January 24, 2010 Erm I tend to have around 20-30. Seems to me that it's perfect as the rim hits when dropping off etc but gently. And people who run lower pressures tend to be smoother riders... Quote Link to comment Share on other sites More sharing options...

And people who run lower pressures tend to be smoother riders... What? No they don't. People who run lower pressures tend to prefer lower pressures. What about Danny Macaskill? He runs 60 front and rear as far as i'm aware. It all depends on personal preferance and your style of riding. Natural riders sometimes prefer higher pressures. This is because rock and other natural things tend to be more points than street stuff, running the higher pressures helps prevent punctures and rim damage. Street riders in the trials sense tend to run them a bit lower so that the tyres can really grap around the obstacles there using. Modern street riders (24" mainly) tend to run closer to street MTB and BMX pressures so there bikes turn better in the air and don't catch on the tyres on landing or take off. Its mainly personal, the best way to do it is try out alot, tyre pressure is one of the easiest if not the easiest thing to change on your bike.

Dan6061 Posted January 25, 2010 Report Share Posted January 25, 2010 I used to run about 7psi. But then I realised it was silly, so now I have around 15? Which in comparison feels solid! It's all down to personal preference though, just play about with it and see what you like. Quote Link to comment Share on other sites More sharing options...
davey1991 Posted January 26, 2010 Report Share Posted January 26, 2010 Wut? I couldn't remember what i was saying half way. When taking of to do 360's and the like higher pressures prevent the tyres catching on the floor and slowing your rotation. I don't like trials....
