I'm with Booth on this.
After having various alloys damaged over the years I now go to a wheel refurber to have my tyres changed.
They aren't going to spend days refurbing wheels to then damage them putting the tyres back on so they are perfectly placed for this.
I also looked into getting my own equipment to change my own tyres and its surprisingly not that expensive. Unfortunately I've no longer got the space or I think I would invest.
