The Airstop Butyl tubes are an economical long lasting tube, with good puncture resistance. 0.9mm wall thickness for optimum puncture protection and also the butyl tubes provide better resistance to friction caused by spokes and old rim tape.

I do 3000 miles a year with these. Never missed a beat. I do change them at the beginning of the year as I keep them inflated to 100psi.
I don’t see how other reviewers blame the tube for getting a puncture – that’s the fault of the tyre. Or the user mis-fitting the tube in the first place.

I bought two of these because they are from Michelin. I should have listened to the reviewers. Developed a puncture on my front wheel on the first day. Then puncture on my rear a couple of days later. May be it is just my luck but buyers beware.

Bought a pair of these together with Michelin road tyres. Installed together with the new tyres and on clean rims + rim tapes. Rear tyre got flat on the second day and there were no puncture involved. I repaired the very very small hole just to discover there was another. Both so small you can't see them if the tube is not inflated, so the fault must be in the rubber itself. The other tube is fine.
The valve looks nice with brass-coloured body and it's smooth (no threads).

Initially they look good and feel much more rubbery as opposed to cheap plasticy tubes.
Tough, lightweight, etc etc etc
BUT if you do get a puncture, for some reason glueless patches just won't stick to the material! So you need to have an old school puncture repair outfit, or buy a new tube when you get a flattie!
