To go back to the tyres not fitting past the brakes - I run 25c P2Rs and 105 calipers with KoolStop Salmon pads - even with the QR undone the inflated tyre will not fit past the blocks, the tyre needs to be deflated.
Not a problem for me as I only remove the wheel either if it is punctured, or when I am fettling / transporting the bike in which case I have my track pump to hand.
