If you are going to buy tyres online, please phone the local place you're planning on having them fitted for a price for fitting tyres you bring in yourself. Many bike shops including the one I use charge much more if they don't supply the tyres as it's still their time, their equipment, and often them disposing of the old tyre.

Many places make little or no money on the fitting, and make it all on selling the tyres, so they're not going to offer the same price if you bring that part along with you.

That's not to say you can't work a good deal out by getting your own tyres online, but you do need to make sure you're aware of all the costs before you buy.
