With the right air pressure, mountain bikers can get the most out of their bike. But the right pressure is as individual as the facets of mountain biking. Schwalbe now offers an online calculator for guidance: The Schwalbe Pressure Prof uses nine parameters to determine the optimum tire pressure.

As the only connection between the bike and the ground, the tires influence handling like no other component. "But they are rarely ridden with the correct air pressure. Many bikers have far too much or too little air in their tires and are therefore unable to exploit the potential of the
potential of the tire or the bike," explains Carl Kämper, Schwalbe Junior Product Manager. "With the Pressure Prof, the optimum air pressure in the tire can be calculated precisely and quickly online - for all mountain biking disciplines with several options for every application."Only for Schwalbe tires

The Pressure Prof thinks of everything: it evaluates nine parameters, from rider weight and rim width to the surface. These and many other calculations are based on an algorithm that incorporates Schwalbe know-how from decades of research and development. The recommendations therefore relate exclusively to Schwalbe MTB tires.

Even experienced riders get new impulses, because the pressure is recalculated and optimized for each use. For example, the Prof knows that when using tubeless or Procore, the specified minimum pressure on the tire may be undercut due to the higher puncture protection and takes this into account in the calculation. This means that new performance limits are possible. "Good tire pressure is the simplest and cheapest tuning method for any mountain bike," summarizes Carl Kämper.

Tricky values

The trickiest part of the application is probably the selection of the tire width: This must be specified in millimetres, but is much more familiar to most mountain bikers in inches. A glance at the sidewall of the (Schwalbe) tires shows the width in millimetres as well as the inch measurement. The same applies to the inner rim width: this is often not very familiar either, but a look at the bike and then at the rim manufacturer's website could provide clarity in many cases. Otherwise, even if it may be a little awkward: deflate the wheel and measure the rim width with a ruler.
