Several threads ran on TM back in 2015 and there were many front tyre pressure preferences ranging from 25 psi to 30 psi though one person liked 37 psi which to me seems a tad high. The pressure marked on the side of the tyre is usually only a maximum pressure for that tyre and will have little bearing on actual pressure for the vehicle to which it is fitted. The 22psi sticker which Betty referred to would certainly be correct for a 4 wheeler Morgan though.
