Schwalbe & Syntace introduce dual-chamber tyres for ultra low pressures

[MTBc]

i wonder how many okes will get the valves confused and run high psi on the outside and low on the inside

Haha

 

And how would you know if / when the inside chamber is flat?

Tyre pressure gauge perhaps?

I dig the part where the test rider "pinch flatted" the inner tube and as a result got more pressure in the outer.

Yes, but I'm talking about while you are riding. No way to feel if the inner chamber is flat?

Might work in Europe where they don't have thorns but here in SA I'm not sure.Nothing said about running slime etc.I know from motorbike experience if you puncture the inner tube it's a biiiitch to sort out trail side.Dont see this working for mtb.

if the inner is flat, its likely the pressure in the outer tube will increase, as happened during the testing.

 

However, if it doesn't leak into the outer tube, you will no doubt feel the whole tire as acting 'squishy' and you'll be all over the place as occurs when riding any other tire that's gone flat. Remember, the inner chamber is high pressure to provide sidewall support so the outer can be run at silly low pressures.. without that inner chamber high pressure, the whole tyre wall gets all flexy, and you suffer the squish.

I was wondering about that now, how does one fix the inner tube if there is a thorn that goes through the outer tyre and inner tube, thats exactly the same as running tubes, kind of sounds like gong backwards from the standard tubeless.
