Best road bike tires pressure: Is it important to inflate tires? The answer is yes! A well-inflated tire is different from a tire too much or not increased enough. Unsuitable pressure enhances the risk of punctures, which is why it is essential for the cyclist to improve his knowledge on the subject.

With a slightly inflated tire, you will drive less quickly and therefore you will need more effort to advance but will gain in comfort. Conversely, a high pressure inflated tire will offer you better performance because there is less contact with the road, but also less comfort. It is then necessary to find the perfect compromise between comfort and efficiency, without being in extremes that increase the risks of punctures.

Best road bike tires pressure: Find the Right Pressure

There are several parameters to take into account such as the weight of the cyclist, the model of the tire, the inner tube, etc. What it is important to do at first is to look on the side of the tire. Most of the time you see enrolled in BARS or PSI (or Pound per square inch), minimum pressure or low pressure and maximum or high pressure.

Note that the more you rely on the maximum pressure, the harder your tires will be, you will feel much more road imperfections but have a better performance. The closer you get to the minimum pressure, the more comfortable and grip you feel. You also notice that ATVs often have a lower recommended tire pressure than road bikes. It is, therefore, important that you take into account the terrain in which you practice to inflate your tires.

Another parameter to take into account to inflate your tire: your weight. The 10% rule can guide you. One often talks about calculating the pressure by taking the 10% of the weight of the cyclist (and baggage if these are important). If you weigh 75 kg, you can count at around 7.5 bars. However this indication only serves to get an idea, for the lightest and heaviest of you, you must not leave the low and high pressures indicated on the flank.

Finally take into account your position on your bike. A city bike rear tire supports 2/3 of the load. It will, therefore, require a slightly greater pressure than that for your rear tire.


Although most of the time, the recommended pressure listed on the sidewall of the tire to a road bike, they have only a guideline.

This is usually the maximum permissible pressure and sometimes the minimum pressure. However, all this will have to be adapted according to the practice, the type of road, but especially, the weight of the cyclist.

Best road bike tires pressure: How much pressure does it take to inflate racing bike tires?

Many people only swell as high as possible, thinking that the performance will be better. Error. If in relation to your weight, you over-inflate, there will be a loss of return, especially on bad roads or in a dancer where the tire, rather than deform, will tend to bounce on the macadam. This leads to significant losses in the transmission of energy.

Best road bike tires pressure: Pressure to adapt according to your practice

Practitioners ATVs have long understood the importance to change the pressure depending on the ground. Ground rock, grease, mud, etc. to each surface, they adjust the pressure even their tires.

Only the cyclists on the track will have an interest in adopting very high pressures (10 bars or more), but in their case, the coating is in general perfect.

Best road bike tires pressure: 10% of the weight

In general, the pressure to adopt and 10% of the weight of the cyclist. This rule is rather well adapted, although high and low limits will not be exceeded for the lightest and the heaviest.
Beyond 80kg, there is no need to over-inflate. It is advisable not to exceed 8.5 bars, even for a cyclist of 100kg.

For lighter cyclists weighing less than 50kg, the level limit of 6 bars is a minimum below which it is not advisable to climb down. Otherwise, the tube may be pinched in potholes.
These values are only indicative and will have to be adapted, to the extent reasonable, to each. Depending on the type of road you take during your trips, your preferences, you can vary some of these pressures (+/- 0.5 bar).

However, you will have understood, inflate its tires to 9 bars and beyond will not bring you anything regarding performance, quite the opposite. Just get a good back pain!
For my part, with my 73kg, I inflate to 7 bars max for the rear and in general, 6.5 blocks for the front. Big enough in most cases and I do not burst more than the average (a puncture a year).

All these pressures are given for standard tires in 700 × 23. For tires wider in 700 × 25, you can easily opt for a pressure of 0.5 bars less compared to this graph.

Special case of paving stones

On the cobblestones, pro riders are used to using 28mm hoses for comfort.

For example, during his Paris-Roubaix victorious, Fabian Cancellara used 27mm inflatable tubes at 5.5 bars at the front and only 6 bars at the rear. When we know that it weighs 81kg and that did not prevent it from rolling at about 45km / h of average …

Best road bike tires pressure: Essential foot pump

To reach such pressures quite quickly, do not count on a mini-pump that is reserved for roadside breakdowns in the event of a puncture.

A high-quality foot pump with a manometer will allow you to reach pressures of 7 to 8 bars with precision quickly.

Best road bike tires pressure: Watch out for the valves!

It should be noted that in the bicycle world, it has several types of valves, two of which are particularly common: the Presta (large and elegant) and the Schrader (small and large). An article showed you the different types of valves on Cycle. We must, therefore, choose the right bicycle pump is compatible with your valve and in particular a bike pump capable of reaching high pressures. However, above all, do not forget to unscrew the valve before pumping (you will soon realize it anyway).
