I run my tires at 32f and 30r, Just makes the bumps a little softer. Info from my racing buddieson the tyre pressure for getting the bead to pop
its not unusual to need 50-60psi to get it fully home.
then set to 42 or what ever you run em at:thumb:
when i worked in a tyre shop some tyres were quite stubborn and a little soap works wonders when fitting.
