Normal Road Bike Tire Pressure

Your weight is also a factor.

Normal road bike tire pressure. Any kind of water on the road decreases the grip of the tyres so it s prudent to lower tyre pressure. Road tires typically require 80 to 130 psi pounds per square inch. Road bike tires typically require 80 to 130 psi mountain bike tires 30 to 50 psi kids bikes 20 to 40 psi and hybrid bike tires 50 to 70 psi. And hybrid tires 40 to 70 psi.

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. If the bicycle and rider. The psi of the tire must equal the weight placed against the tire so the size of the contact patch will be the weight load divided by the air pressure approximately. Narrow tires need more air pressure than wide ones.

For instance on a road bike a 200 pound rider should add 20 more psi than a 165 pound rider. To find your ideal pressure start in the middle of these ranges then factor in your body weight. 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.
