Mini wheels are pretty easy because they are just so small to handle. Achmed is on to it. Videos are the go!
Some pointers which come to mind:
* Don't attempt it unless you have some dishwashing liquid and a brush. I only mix about 50% water in it, so real thick and slippery.
* Don't attempt it without good boots, to break the bead and also to hold the beads in the middle of the rim on the opposite side.
* Remove the valve core to deflate.
* Start and finish with the levers at the valve stem.
* The less experienced you are at it, be super careful not to pinch the tube. Use a little torch if doing it at night time.
* Removal: Tube removed fully after you get the first bead off. Yes it can hurt your hands to best to toughen up.
* Installing: Semi inflate tube. Holding wheel vertical between your legs when standing - Valve stem just into rim, then tube into the tyre, then get the rim lock in place and put one bead on. Check rimlock is free to move. With good soap lube the first bead often goes on without levers.
* Think and don't go beserk with the levers. The levers are needed for just the very beginning or end of each bead wire. The rest is by without tools. Actually you use hands, feet (if the wheel is laying flat) and sometimes knees when holding the wheel upright to really deform a tyre and rip it on or off.
* Some cheap china tyres are so crap they just rip off by hand like BMX tyres. More expensive tyres, especially full sized, are much harder to get on/off.
* Look after your discs. Think about which side will be on the ground when you stand on the tyre.
