The 7 keys to correct tire pressure

This is one of the eternal debates in cycling and other wheel sports since incorrect pressure can turn your ride into a real ordeal. Here are the 7 keys to correct tire pressure:

Preliminary Considerations

Before you start, it is advisable to have slightly less pressure in the front wheel than in the rear; normally 0.1-0.2 bars less in the front than in the rear. This is because we load most of our weight on the rear wheel, so we need to inflate it a bit more to reduce rolling friction.

  1. Rider Weight

You should not only consider the rider's weight but also the total weight: rider, clothing, accessories, and bicycle. For example, e-bikes have specific reinforced tires due to the increased weight, among other factors. The greater the weight, the higher the pressure needed to avoid punctures, premature wear, and tire deformation.

  1. Wheel Diameter

The wheel diameter also matters when setting the correct pressure. The larger the diameter, the lower the pressure. For example, 29" wheels hold a greater volume of air than 27.5" and 26" wheels, requiring lower pressure.

  1. Tubeless Tires?

Running tubeless allows you to ride with 0.2 to 0.4 bars less pressure. The absence of an inner tube reduces the risk of pinch flats and allows you to ride at lower pressures, gaining grip, traction, braking, and comfort.

  1. Type of Terrain

It is crucial to know the type of terrain and adjust your tire pressure accordingly. The more rugged, rocky, or steep the terrain, the higher the pressure you will need.

  1. Riding Level

Riding level can be a double-edged sword. Experienced bikers can ride at lower pressures thanks to their technique, but they also face higher risks of punctures due to increased speed.

  1. Wet or Dry Terrain

On wet terrain, you need a greater contact area with the ground to maintain control, so it is advisable to lower the pressure by a couple of tenths. In extreme cases like snow, pressures can be very low to increase grip.

  1. Tire Width

The wider the tire, the greater the internal air volume, which requires a reduction in pressure. Fat bike tires, for example, have huge volumes, and their pressures are very low, even below 1 bar.

Conclusions

These are the 7 keys to the correct tire pressure. However, trial and error always prevail. Science can explain almost everything to you, but sensations often take precedence. I invite you to try these tips and share your experience.
