TirePressureCalc.

This calculator is estimating the fastest possible pressure based on real world data taken with professional athletes riding professionally specified and maintained equipment. This calculator makes no claims to the compatibility of the rim/tires you have chosen, nor does it read the internet deeply enough to know the limitations of your setup as specified by ANY of the manufacturers of the various components in your setup. If this calculator recommends pressures that violate ANY of the limitations of your manufacturer's specifications, you must either change components or lower your pressures to match those of the manufacturer.

Note: Tubeless setups, particularly those not adhering to ETRTO (European Tyre and Rim Technical Organisation), OR hookless setups are VERY sensitive to pressure and surpassing manufacturer's recommended pressures can lead to unnecessary risks including injury, equipment damage, and you guessed it: death.
