You may not give a monkeys about what speed you ride, but never the less , if you can go faster without putting any more energy in why wouldn’t you?
I have always been guided by the school of thought that a narrow tyre @ 115 psi is the best way to roll.

If you do decide to buy some new tyres come down and see us. We have some very nice tyres in stock.
