There doesn't seem to be much clearance between the front brakes
and the wheel on my 17s. (Just noticed today. Can't be more
than a couple of mm.
Is this normal?
I had 17s on my first Brera and you're right, there is very little clearance between rim and calliper. When you come to have tyres changed it is worth pointing this out to the fitters before they stick on normal weights as they will get wiped off with the first rotation.
