Supporting Bike While Changing Both Tyres

[darrsi]

That sounds a lot like the new practice after people starting buying from online dealers.
Especially in Norway they charge ludicrous amounts if you don't buy the wheels from them.

I've always bought online tyres then had them fitted after taking my wheel into my bike mechanic.
When I had a rear puncture a few years ago I got charged something like £164 to have a new rear tyre fitted when I managed to ride to a bike tyre shop, and that was with a bit of discount apparently.
I just checked and can get that same tyre delivered to me now for £96, and my mechanic will certainly charge no more than £20 to fit it.
