Tyre Removal

[Grundy]

I need to remove and re-apply the tyre to one of my front wheels (as it's not seated properly). I know there's 3 main ways to do it; baking, boiling and acetone.

I don't have acetone (and i don't think i should be messing with that stuff!). So what have you guys found most effective; boiling or baking?

also, how long do you boil/bake for? most people say 5-7mins
