Running Velocity A23 (23mm) rims with 25mm tyres for winter - general consensus is that you drop 10 psi for a wide rim OR a wider tyre but what about if you have both? Is it 20 psi, just 10 or somewhere in between? Cheers

    People can recommend pressures, OR you can do it the proper way, go out with a pressure gauge, a pump and tyres pumped up to a higher than optimal pressure to start with ( front pressure about 90% of the rear pressure) find an empty car park and do a bit of hard & fast cornering, keep letting 5psi out at a time until it feels right. Obviously if you get to the point where they feel dodgy , add 5psi until they feel right.

    85/80 should be enough, unless you are a serial pothole hitter
