Or do it the right way with a tyre beader. You can buy one from any good trials dealer and it will pay for itself in no time with ease of fitting safely.

Its basically the bmx innertube made of sponge and works a treat.

Tyre beader every time. I have tried all of the alternatives and the tyre beader is so much easier. Use tyre soap or a weak mix of washing up liquid and water on the tyre and the beader, this will help the beader pop out. Take the valve core out to get a good rush of air to get the bead on the rim.

using a beeder its possible to get a tyre to seat with a foot pump.
