Hi it has been a while.
I just replaced worn tyres with new ones and decided to up to 25mm, on my Moda road bike. The old ones had a real flat middle on the rear. I weigh 70kg the bike is around 9 kg and I frequently ride with a backpack full of groceries. say 7 kilos.
They are on and what a difference new rubber makes. But I need to decide what pressure to ride. I rode115 psi on the old ones unloaded and 120 loaded and the charts say 90 psi for the new tyres. But should I take the 23c into consideration or just ignore it.
It is riding well, but I just wanted to check.
