I believe people use 23c tyres on the track (you can confirm with RPM while you are grumping) and a 23c tyre is too big to allow the wheel to go much above halfway up the track end.
But the reason the tyre rubs is because the bridge has a square section in the middle to accomodate the brake. It that wasn't there it wouldn't rub as I only had to file the square flush with the rest of the bridge.
So if it's a track bike, designed solely for the track then why does it even have a brake bridge!
