The door frame sticker here in the States is recommending 46 psi. on all 4 corners all the time.
They think we’re a bunch of fat asses?
I do 41 psi. fronts and 38 psi on a usual day, I only crank it to 46psi when it’s fully loaded.
My first set of tyres lasted 40,000+ miles.
Over inflating is bad, will wear the center of the tyres faster.
