    All the silly comments are unecessary.
    But I would suggest riding outside.

    You haven't seen the OP's epic staircase though!

    I don't understand what you're asking?

    What is the best set-up for riding up and down stairs on that bike? What do you mean?

    You keep getting punctures when riding up and down stairs? Put more air in the tyres? What's with the ridiculously big tyres anyway? 2.6" that's not gonna help if you trying to ride up a stair case. Prob easier to carry the bike up the stairs

    Bou a track pump & run your tyres at a higher PSI.

    Burtsing sounds painful.....

    I think you're trying to say you burst (clarify what you actually mean by that) the rear tyre when riding up/down stairs, if the trye carcass is failing (sidewalls) its almost certain you're not running the type at a high enough pressure and the sidewalls are getting pinched twixt rim and stair edge (concrete?)

    Also probably a good idea not to be seated when riding down stairs. Weight back and just soak up the bumps same as riding down anything of the same gradient...heck stairs are easier than rocks

    I'd recommend buying a 36er

    My mate has one - I wouldn't ride that down stairs, 29er maybe!

    My advice is to just sell your bike and take up knitting or something.
  • As people have said, more pressure will help prevent pinches, as will some DH tubes if you can handle the weight and want to run lower pressures. I used dmr moto diggers (very thin sidewalls) and standard tubes with 100psi and didn't have any troubles with pinching on steps

    For going down stairs, I recommend going bump, bump, bump, on the back of your head, behind Christopher Robin. It is, as far as I know, the only way of coming downstairs, but sometimes I feel that there really is another way, if only I could stop bumping for a moment and think of it.

    Please dont slate, ill try answer a few Qs and thanks to the ppl who helped. Ive been riding for 10years, I grew up inner city so havnt had much access to offroad (obviously taken it up when possible). I popped many front tyres (each time getting better tube, tires and finally wheel) and finally got a spank tweet 28mm rim, 2.7 high roller and continental DH tube. havnt had a puncture in 2 years. For the back I thought a wider rim would help, a halo sas pro 32mm rim, same innertube. I run the front tyre on 45/50psi and the back on 40/45 (highest 58psi on both tires). What im basicly asking is whether its the bike being completely unsuited to what I use it for; if so recommendations?
    ps. i still get punctures on the rear
  • just to add, ive tried the 2.35 high roller, minion etc. hence the ridiculous size (im not overly keen coz there heavy as ****) but it stops the front poppin

    I think no one is quite sure what you use it for. Going down/up stairs is an odd use for a bike.

    But I have lightweight wheels and tyres, normal tubes and run pressures at around 25 (front) to 30 (rear) psi.
    I ride 99.9% offroad, mainly natural trails with all manner of stuff in them, roots, rocks, small drops, little jumps (being non heroic).
    I haven't had a puncture for over two years.

    So......

  • its not just for stairs, i just enjoy it..its makin the most out of wanting todo downhill in town i suppose, would lower or higher pressure be better?

    Is it punctures, or are you actually damaging the tyres? Punctures on this sort of thing would be an indication of too-low pressures.

  • Are your innertubes the correct size for the tyres?

    I often ride down steps on my regular MTB on 2.1" panaracers and not had a puncture from it.

    What is ACTUALLY happening when the 'tyre bursts'? Is it a inner tube puncture or litteraly the tyre carcass bursting? Are they 'pinch flats' (otherwise known as snakebites as you get 2 holes close together) as that would be a sure sign of not enough pressure, although I run mine at 30 and not flatted down steps (don't ride up them though!) are you sitting or standing, if your out the saddle, weight right back, maybe even too far back? Is it on ups or downs?

    Seems weird for sure. I ride down stairs on all the bikes with all different tyres, wheels (XC, AM & DH) at all different pressures (and always bog standard inner tubes)

    And like I said before stairs are so uniform there's nothing that can catch you out, just roll down them. Must be some other issue as even at low pressures unless you're jumping from the top step and hitting the stairs hard there's no reason why riding down stairs would result in a puncture

    Are you repairing the burst tubes or just putting in new ones? One particular set of stairs or just stairs in general?

    Is this a street trials question then? Might be best off asking on a specific trials forum?

    I used to ride street a lot when I was a nipper (hieght of the Marti(y)n's popularity) but never had any trouble. I agree we need more info regarding the term 'burst' but I would have thought any half decent tyre would be ok, if you're wrecking a lot doing trial I'd concentrate on technique rather than throwing money at the problem.

    I'd say this is a pretty good setup...

  • I use 2.5 -2.7 innertubes, its usually snakebites, even tho i run around 45psi, I always stand, going down is 99% fine; its going up, 40% I wont get a flat and I always hit them at speed. as for bursting my tires, Im talking about a split that nearly rips the tube in half or a 2inch odd gash length-ways, sometimes tire comes off the rim. The tire has never been damaged though.

    You're trying to ride up steps at speed, and wondering why you're getting pinch flats? :?

    If it's a single step learn to bunny hop - your wheels shouldn't touch them.
  • Im not wondering why, surely the advances of todays bike technology could prevail?
    plus I do bunny hop up few stairs, just am more amused by using it as a ramp
