Tire pressure: A definitive guide? Beállítások

One of the cycling issues I’m kinda frustrated with – especially given the amount mathematical brain power orbiting around and within cycling – is there is no, single calculator that can give you an optimal front/rear tire pressure recommendation for asphalt based on tire width, internal rim width and weight – for both tubeless and tube-d.

My question in all of this about lower pressures is where do manufacturer minimums come into the equation, if at all? Why do the manufacturers advise a minimum? Should it be taken into account when selecting a lower operating pressure or is it to be ignored? That’s something I have yet to hear a clear answer on, whether from silca, trainer road or others.

At the end of the day, even aerodynamics isn't the most important thing! To finish fast, you have to get to the finish line in great shape. Even if a 19mm tire on a skinny rim is fastest when considering rolling resistance and aerodynamics, if the high pressure required to avoid flats will beat you up to such an extent that your legs will be toast (as will your will to live) and your legs won't put out any power to speak of. Going to a wider tire at lower pressure is probably faster in that case.
