For motorbikes? I break the bead with an Abba tyre thingy. Many use G-Clamps. Just get some protectors - I've done ali wheels for years and left no marks.

If you think you need tyre levers longer than 6" you're doing it wrong. Get the bead into the well and be patient.

The problems I have are with getting the new tyre on. Winter's worst as the tyres are cold and less pliable. Even if they're warmed up overnight. Although now I live alone I can do this in the living room so it'll be warm.

Get tyre soap. Use loads of it. Then put some more on. Then a bit extra for luck.

I beg wheel weights from kwik fit and balance them myself. I find it cathartic.

I've never replaced valves - I think that's a money making exercise for tyre shops.
