Tire Pressure For Road Bike Racing

Tire width and compression.

Tire pressure for road bike racing. For a 700 x 23c tyre on the road a 55 kg rider should start with 100 psi while a 90 kg rider should run closer to 120 psi. The amount of weight that will be exerted on the tires does play a crucial role in how much pressure you will put on a tire. Tire width rider weight and road surface condition. 26 mountain bike tyres usually 30 to 50 psi.

Hybrid tyres around 50 to 70 psi. Knowing your tire maximum your decision will always boil down to three considerations. 29 mountain bike tyres usually 18 20 psi. Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones.

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. She tested all the way from 119 psi 8 2 bar to 29 psi 2 bar the results were surprising. Emma conducts an experiment to determine the fastest tyre pressure on a rough road surface. Road tires typically require 80 to 130 psi pounds.

Most 700c road tires today are sold in either 23 or 25 mm widths. For example on my touring bike when not loaded and just my body weight and bike weigh calculated using 32 wide tires i use 45 psi front and 70 rear but if i add 55 pounds of gear for touring i now have to raise that psi to 60 f and 90 r.
