I'm lazy so I get a mobile tyre fitter to do it; much easier with all his power tools, air jacks, torque spanners etc. Quick & cheap.

There's usually something that needs attention and obviously he checks condition, pressures and (if I ask) balance too.

My winter wheels (both cars) are actually 1" smaller rims (though in both cases I found very similar-looking alloys to the summer ones) with deeper profile tyres. Works very well.
One has 15" winters and 16" summers, the other 17" winters and 18" summers.
