Tips getting a tight fitting tyre on

[andrew_s]

If "puncture proof tyre" means one of the "plus" models, the reason they are hard to fit is that the left and right sides of the tyre tend to spring apart due to the thick anti-puncture layer under the tread. This means that although you can move the bead down into the well of the rim, it doesn't stay there unless you take steps to keep it there, hence the toe straps on Colin's video above.

Well I got yet ANOTHER puncture in the front tyre of my Brompton which is a SMP+ and I am going to have to take it off to patch the tube or replace it. But the SMP+ isn't going back on as I am sick of them. Heavy, noisy and NOT puncture resistant. I wish Specialised did an Armadillo 16" tyre as I've never had a puncture with one of these tyres. To get the SMP+ on the Brompton rim I very very lightly greased the bead of the tyre and it went on easily just using my fingers, no levers or straps as the old guy uses in the video above. I never have trouble getting other tyres on or off rims just SMP+ but I won't be using them any longer as they are terrible tyres. They just don't live up to all the hype.

Likewise. They don't behave themselves and go floppy all over the place, even turning themselves inside out like a bonkers snake.
