I think their recommended pressures are for safety with how they build their rims and not so much for speed. This not Hed, but Hunt -- they say below info which does not look the same as tire inflator charts, but look like they worry about safety. This is for 18mm rim.
- Maximum tire pressure for this rim is 120psi when used with an inner tube and 100psi when running the wheel set-up tubeless. Please do not exceed the maximum pressure stated on your tire.
- Maximum tire pressures for other tire sizes 30mm do not exceed 70psi, 33mm do not exceed 50psi, 35-45mm do not exceed 40psi, 46mm+ do not exceed 35psi.
- Please do not exceed the maximum pressure stated on your tire.
