Tire Pressure For Road Bike Racing
Emma conducts an experiment to determine the fastest tyre pressure on a rough road surface.
Tire pressure for road bike racing. 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. Road tires typically require 80 to 130 psi pounds. Tire width and compression. 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.
Tire width rider weight and road surface condition. But how should you decide what pressure is best for you. 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. 27 5 mountain bike tyres usually 20 25 psi.
26 mountain bike tyres usually 30 to 50 psi. Most 700c road tires today are sold in either 23 or 25 mm widths. 29 mountain bike tyres usually 18 20 psi. Knowing your tire maximum your decision will always boil down to three considerations.
Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. 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.
