Road Bike Tires Lose Pressure

I use 700x23c tires with 120 psi recommended.

Road bike tires lose pressure. Checking and adjusting the inflation pressure at least once a month with a pressure gauge is most important the sidewalls may be damaged if a bike is left on flat tyres for a long period. Acute observation has noted a strong tendency for bike tires to deflate when the bicycle is not being used by the owner. Road tires typically require 80 to 130 psi pounds. The rate a which a tube will lose air is proportional to the gauge pressure in it.

If you use tubed tires that are between 2 35 and 2 4 inches the pressure per tire should be 29 psi. Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. Tire pressure and blow outs when inflating a tube you need to ensure that the pressure you are inflating it to is the correct amount for that make you will find the tire pressure recommended printed on the side of the tire. 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.

So if you have a. According to enduro mountainbike magazine the psi varies if you have tubed or tubeless mountain bike tires. High pressure road bike tubes will lose air quite quickly when at 100 psi say. If fitted on a wheel tyres should be inflated or the wheel should be hung up for storage.

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. A humorous attempt to explain why tires lose air when the bike is not being used. Due to pressure the rider exerts down and the resistance of the tire on the road. Thus if we assume the same type of tire materials etc.

Any pressure gauge you might find attached to a bicycle pump is at best a rough approximation to the true value of the pressure in the tire. Additionally air loss is also more noticeable on smaller tires because any air that escapes represents a larger percentage of the total volume of air. Why do tires lose pressure. Avoid pinch flats and damage to wheel set check and fill tires to right pressure before each ride.

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. I check the pressure and fill it to recommended before every ride. Road tires lose air more quickly than cross tires and cross tires lose air more quickly than mountain bike tires.
