Road Bicycle Tire Psi

Tire pressure is crucial for safety in cars and bicycles are no different.

Road bicycle tire psi. Bicycle tires consist of a rubber impregnated cloth casing also called the carcass with additional rubber called the tread on the surface that contacts the road. Road bike tires are narrowest and require between 80 and 130 psi air pressure. Road tires typically require 80 to 130 psi pounds. There was a time when most riders would opt for 23c tyres on the road pump the tyre pressure up to around 110psi for every ride letting out just a little air to provide extra grip in poor weather.

In the case of clinchers the casing wraps around two beads one on each edge. Mountain tires are flatter and they need an air pressure between 30 and 50 psi. Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. Here are air pressure requirements for different types of bikes.

Bicycle tire casing is made of cloth usually nylon though cotton and silk have also been used. How much pressure road bike tire should have. On smooth surfaces like the one used in the tests shown above moderately high tire pressure say 100 110 psi for a 25 mm tire actually rolls slower than either a lower pressure 80 psi or a higher pressure 130 psi. Rolling resistance does vary slightly with tire pressure but it s not linear and it depends on the surface.
