Step 1
Tyre not on the list? Just type your global target hot pressure — every corner target and your cold starting pressures are worked out for you from the heat-rise factor. Add ambient temp and, if you can measure it, track temp — neither is required, but the more you give the more accurate the cold pressures. With no track temp we estimate it at ~10°C above the air. Your drivetrain matters too: driven wheels heat up and build more pressure, so we set the driven axle a little lower cold.

Predicted cold set
Recommended cold pressures to hit your targets, using the Semi-slick 3.2 psi heat rise at 20°C air (track temp estimated). Set these before you go out.
