Tyre pressure – How many bars does a road bike tyre need?
The air pressure on a road bike has a great influence on the riding behaviour. The right value depends on how much you weigh, how wide your tyres are and how important comfort is to you. Manufacturers specify minimum and maximum pressure in bars or PSI (pounds per square inch), which you should observe for safety reasons. However, it’s worth experimenting within these parameters. A tyre with high air pressure rolls more easily on smooth road surfaces because it is less deformed. Low air pressure, on the other hand, provides higher comfort. On rough asphalt, cobblestones or gravel, the rolling resistance can even be lower with wide tyres and rather low pressure. This is because the softer tyre can better adapt to the ground and you aren’t jostled around as much. A good floor pump with a precise pressure gauge lets you start every road bike excursion with the ideal tyre pressure, especially when you’ve found the magic number. Enjoy the ride!
