Rebelistic Posted June 7, 2006 Report Share Posted June 7, 2006 I've tried to search for a thread on this but not found one, anyway I often get pinch flats - Any advice on how to prevent them would be helpful or a link to a thread.I've heard putting talcome (can't spell it) powder on your innertube can help, has anyone tried this?Cheers Quote Link to comment Share on other sites More sharing options...
Egg Fried Rice Posted June 7, 2006 Report Share Posted June 7, 2006 tyre pressure is very importanti cant remember where i got it from but i think if your landing on sharp stuff or harsh corners, you need a higher pressure (20+ psi) and when landing on flat, blunt objects such as rail gaps, you should have a lower tyre pressure (below 20psi). this may not be correct so i need someone else to prove it too.John K Quote Link to comment Share on other sites More sharing options...
GTF Posted June 7, 2006 Report Share Posted June 7, 2006 if you ride 26" get a Maxxis Downhill tubeif you ride 20" get a Cheng Shin tubeavilebabe from tartybikes Quote Link to comment Share on other sites More sharing options...
T.McMillan Posted June 7, 2006 Report Share Posted June 7, 2006 If you have an old inner tube cut the valve out and slot your inner tube inside the old one this should help prevent it. I use nokian downhill tubes really nice and thick, I think michelin and maxxis do the same type of tube too, also using the dual play maxxis tyre has slighlty thicker side walls and helps stop gettin pinch flats, I haven't had a puncture from using the maxxis higroller dual ply tyre and I run it very low, but I dont think there is a perfect cure.

Gilman Posted June 7, 2006 Report Share Posted June 7, 2006 I would definatly run a higher tire pressure if you are riding urban, and a slightly lower pressure for natural.Also depending on what tire you are running, you may look into a new one with thicker sidewalls.I was having the same kind of problems, then I switched to a good DH tire with slightly thicker sidewalls then my previous tire, I haven't pinched yet. Knock on wood. Quote Link to comment Share on other sites More sharing options...
chris mac Posted June 7, 2006 Report Share Posted June 7, 2006 (edited) i posted the same thing a while back. i had like 4 snake bites in a week so i just run a normal tube with 22 psi in it does me never had one since. but never go riding with out a pump and other stuff to fix one when you do, its always worth it because it saves you pushing home hope ive helped also make sure that you have plenty tred on your tyre always helps Edited June 7, 2006 by chris mac Quote Link to comment Share on other sites More sharing options...
tom tom Posted June 7, 2006 Report Share Posted June 7, 2006 good tyre, good tube, good pressure and be smoother Quote Link to comment Share on other sites More sharing options...
Rebelistic Posted June 7, 2006 Author Report Share Posted June 7, 2006 Cheers for the help guys I've got a nokian tube now and I'll try a slightly higher pressure as I mainly ride street. I'll see how it goes.I always try to ride smoother but can't help the odd heavy landing Quote Link to comment Share on other sites More sharing options...
sunn_bmixx Posted June 7, 2006 Report Share Posted June 7, 2006 when riding street ride at a higher pressure as you can afford to as you very rairly lack in grip when landing or taking off. But when riding natural e.g. a comp, then you can lower the pressure to gain grip. Remember not to go too low though as you will get tire fold! which can be nasty!Hope that helps Ian Bloomfield Quote Link to comment Share on other sites More sharing options...

Tom_ Posted June 8, 2006 Report Share Posted June 8, 2006 does any one know how talcom powder reduces pintch flats or is it just one of these things there is explanation for Quote Link to comment Share on other sites More sharing options...
JonCongreve Posted June 8, 2006 Report Share Posted June 8, 2006 does any one know how talcom powder reduces pintch flats or is it just one of these things there is explanation forTo my knownledge, although i'm pretty sure i'm wrong, worth a guess anyway....A pinch flat is when the tube is caught between the tyre and the top part of the sidewall of the rim, due to heavier landing, and the tube is caused to rip when part of the tube stays in one place while the other part moves because of friction thus making it rip, and causing a pinch flat.....I think.....So when talcon powder is applied to the tube, it allows it to move more easily so it cannot get caught and ripped, helping prevent pinch flats.I could well be wrong, but it was worth a try Quote Link to comment Share on other sites More sharing options...

High pressures are no guarantee at all, in the last 2 months I've pinched my bmx tyre twice and I run roughly 100psi in it. I also spent a year running about 12psi in the trials bike on street without a single pinch (things have changed now and the fecker bursts the instant I roll out of the garden gate of course) Higher pressures will probably help a little bit with pinches because the tube won't be as floppy and therefore less inclined to stick to the tyre but the real benefit of running high pressure is protection for your rim.
