Trebor Posted July 6, 2003 Report Share Posted July 6, 2003 I've been experimenting loads recently with my tire pressures, I chatted with Olly C and was amazed at how higher pressures he ran, so I thought I'd give it a try, I only went as high as 60 P.S.I. I liked it alot, but then I thought I'd try the opposite, and went down to about 12-15 P.S.I. which I really really like! What's annoying is that I have got a slow puncture in the back tube now thanks to those high pressures! :- And I can't be assed to order a new tube!

munkytrials Posted July 8, 2003 Report Share Posted July 8, 2003 use to run 40psi front and rear but now i run 20-25psi up rear and 25-30psi up front, works great, havent had pinches up back for like 8 months now as for the front ah well pinched it once but i dont care if i pinch the front because its less of a hassle to repair than the rear.

Wright Pads Posted July 27, 2003 Report Share Posted July 27, 2003 Wow, how many rims have you split so far? None, if you fit the tubes and tire right and do the prelaoding of bed and have a qualty rim you will be fine. I only pump them to that presures then relese them down slowly.

I only pump them to that presures then relese them down slowly. and what would be the point in that.....160psi aint easy to pump up.....ie actually puttin all your weight on a track pump, like to see you try n get 160!!!!! ne1 who has worked in a bs and pumped up a roadie bike to 120psi. i couldnt have got it much higher than that Link to comment Share on other sites More sharing options...

I only pump them to that presures then relese them down slowly. LOL... Why bother though? Also, like Ian says, its damn hard to get that sorta pressure! What do you use... a rifle pump!? And what rim tape have you got on that Koxx rim... must be pretty strong to take all that pressure :- Im sure the Koxx rim isnt as tough as a 521... and Mavic reccomend a max pressure of 56PSI with a 2.0" tyre... Here it is... I dont doubt the fact that you do pump up your tyres to 160 PSI (*snigger*) but if you are... then i suggest you stop - its fookin dangerous!!

N.Wood Posted December 20, 2003 Report Share Posted December 20, 2003 (edited) on the back I run a crappy wtb 2.4 and a second slick and a standard tube on an old sun rhyno. I think I run it at about 30p.s.I, but I dunno cos I don't have a guage :D the front I run about the same pressure on an irc mythos 2.1k, a standard tube on a mavic f219 disk. I hav'nt had any punctures for about 6 months. I have now got a guage from santa( :-" ) and on natural I ran 18 psi on the tyre, rim and tube above. But I only weigh 9 stone cos I'm only a nipper. for street, though, I run about 25. Edited December 31, 2003 by madbiker66 Link to comment Share on other sites More sharing options...

Dan Clark Posted December 29, 2003 Report Share Posted December 29, 2003 20 psi on the back, Intense Blurr, standard tube 25 psi on the front, shit Ritchey thing, standard tube Not a single pinch flat all year, though I did get a thorn in the other side of my Koxx rim, through one of the holes :- Link to comment Share on other sites More sharing options...
nb88 Posted December 29, 2003 Report Share Posted December 29, 2003 I ride mod with Luna tyres. I usually use 30-35 psi on rear and 40 psi up front. Althought on my crap old onza t-bird I had to run about 40-45 psi or id get pinch flats straight away because of the rubbish BMX tyres. Can running a high pressure buckle your wheels faster? because there isnt as much shock absorbance and it goes into the rim, or am I just thinking complete garbage? :- Noz.
