Diz Posted June 17, 2008 Report Share Posted June 17, 2008 (edited) Was just wondering what sort of pressure people run their tyres at? Whats the optimal pressure for bump absorption whilst also resisting pinchs? Also, whats prefered: Lightweight thin tube with increased risk of puncture/pinch or Thick tube with less risk of puncture/pinch but increased weight.

Bigman Posted June 17, 2008 Report Share Posted June 17, 2008 Maxxis walterweight innertubes are very good, abit lighter than a halfords tube but have a bigger volume so they do not stretch as much when filling the tyre I tend to run my tyres and 20ish psi rear and 18ish front and considering i am 19.5st ish thats quite soft but i don't pinch too often either (maxxis tyres) Adam Quote Link to comment Share on other sites More sharing options...
Echo-Scott Posted June 17, 2008 Report Share Posted June 17, 2008 I go for the biggest tube i can get in the tyre. At the moment i'm runnind a kenda 19" DH tube. It hardly fits in the tube but it does stop pinch's really well. I run my back at about 10psi and my front at about 10psi aswel, Only have a halfords tube in the front though.

Diz Posted June 17, 2008 Author Report Share Posted June 17, 2008 Something confusing you? I'm just amazed at the fact that being 19.5 stone and running the tubes at 20ish psi doesnt result in multiple pinchs. Very impressive Quote Link to comment Share on other sites More sharing options...

Well as soon as i get my car sorted i'm hoping to get along to some of the organised rides. Definately looking forward to riding with people who are much better (and smoother) than myself and generally hanging my head in shame No offense meant btw Also just watched a vid of his, definately smooth.

Captain Scarlet Posted June 17, 2008 Report Share Posted June 17, 2008 A tube is a tube to me when it comes to weight, I'm running a Kedna DH 19" tube in the rear and its not a massive difference on weight (once its in the bike). For me, getting the rear wheel in and out of the bike is such a pain, so I really want a tube to protect me on the rear. Front I just have a generic bulk ChengShin tube.

BenLeacock™ Posted June 17, 2008 Report Share Posted June 17, 2008 humm i had maxxis tubes seem'd to die fast ? Now ive got a 2.5 tyre, with a specilized 2.4-3.0 tube, very heavy but doesnt bother me weight wise. No joke its like a tractor wheel now lol Quote Link to comment Share on other sites More sharing options...
Alex@Flawless Bikes Posted June 17, 2008 Report Share Posted June 17, 2008 Asda tubes for £1.80 can't go wrong, just stock up on them! Quote Link to comment Share on other sites More sharing options...
psycholist Posted June 17, 2008 Report Share Posted June 17, 2008 I run my tyres rock hard by trials standards as far as I can gather with 30 psi front and back... I'm trying to see how low I can go with the pressure before the tyre starts squirming on side slopes on the back wheel... Given the scales at home puts me somewhere around 15.5 stone and I do a lot of street stuff involving square edges, I'm a big fan of running a DH tube inside a 2 ply tyre in the back. Haven't pinch flatted in a long time . Quote Link to comment Share on other sites More sharing options...

Revolver Posted June 17, 2008 Report Share Posted June 17, 2008 (edited) I've got a 2.5mm thick kenda one, apparently halo are making one that's even thicker! Pressure-wise, around 18psi, I think. Might be 20 atm. Edited June 17, 2008 by Revolver Quote Link to comment Share on other sites More sharing options...

craigjames Posted June 18, 2008 Report Share Posted June 18, 2008 raleigh branded cheng shin tubes, the 1.5-2.1 jobs. front and rear. about 25psi front and 20 rear. Quote Link to comment Share on other sites More sharing options...
dan_addison Posted June 18, 2008 Report Share Posted June 18, 2008 A nice thick DH tube and tyre combo should minimise(sp) the risk of punctures. DH racers runn quite low pressure in there tyres for wet condtions and hardly ever flat. Id imagine proformance in nice hot weather on a trials bike would be even better Quote Link to comment Share on other sites More sharing options...
