Ideal Road Bike Tire Pressure for Maximum Performance and Comfort

Although high tire pressure has been proven to increase speed on velodromes, excessively high tire pressure can make rides slower on road bikes. Why is that? We will discuss it in this article.

On road bikes (racing bicycles), roads that are often uneven cause problems when using high tire pressure. Uneven surfaces, such as small potholes, speed bumps, and other irregularities, make the bicycle vibrate and bounce. Although these vibrations feel fast, in reality, they slow the bicycle down.

Lower tire pressure can be a solution. With lower pressure, bicycle tires can adapt to uneven road surfaces without making the entire bicycle move up and down. This is not only more efficient, but also improves the tires' grip on the road, providing greater confidence when taking turns and descending at high speed.

Bicycle tire pressure should be adjusted according to the overall system weight, which includes the weight of the bicycle, the load being carried, and the rider's weight. To determine the appropriate tire pressure, you can use a tire pressure calculator available online. Tire width also plays an important role in determining the required pressure.

It is important to ensure that the selected tire pressure does not exceed the specifications of the rim and tire being used. This can cause problems with the safety, performance, and service life of these components. For example, here are the tire pressure specifications for the Strummer Aeroflow Pro D35 carbon rim:

Table: Example of tire pressure limit specifications for the Strummer Aeroflow D35 carbon rim. These specifications apply only to the Strummer Aeroflow D35 carbon rim. Other rims may have different air pressure limits.

Therefore, high tire pressure is suitable for velodromes with smooth surfaces, while lower tire pressure is more recommended for road bikes ridden on roads that are often less than perfect. This lower tire pressure can improve speed, comfort, and safety during rides.
