Minimum Road Bike Tire Pressure
Expect to use higher bike tire pressure if you weigh more.
Minimum road bike tire pressure. 27 5 mountain bike tyres usually 20 25 psi. Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. If you re riding a mountain bike instead of a road bike the tire pressure is not going to be the same. Riders enter measurable data like their weight tire width rim width tire system tubed tubeless or procore and which of schwalbe s tire casings they re riding.
Rider bike lb. 26 mountain bike tyres usually 30 to 50 psi. 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. According to enduro mountainbike magazine the psi varies if you have tubed or tubeless mountain bike tires.
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. 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. Road tires typically require 80 to 130 psi pounds. For every 10 degree drop in fahrenheit temperature your tire pressure drops by 2 percent such that a drop from 80 to 50 degrees translates to a drop of 100 to 94 psi.
If you use tubed tires that are between 2 35 and 2 4 inches the pressure per tire should be 29 psi. For instance on a road bike a 200 pound rider should add 20 more psi than a 165 pound rider. The higher rolling resistance of the bigger tire is because it provides more comfort at the 15 tire drop air pressure. On a new smooth road your best tire pressure might be 100 psi but bring it down to 90 psi for a rough road.
Your weight is also a factor. In drizzly or rainy weather also lower the pressure by 10 psi for improved traction. The pressure prof takes nine different factors into account when calculating its suggestions for ideal pressures. Mm inflate to psi weight of fully dressed rider bike rider bike lb.
At the 15 tire drop air pressures which are very close to the recommended air pressures for a given size the tables are turned and a bigger road bike tire will have a higher rolling resistance. Hybrid tyres around 50 to 70 psi. Ideal tire pressure is subject to many variables such as road surface weather conditions bike materials and setup rider s weight and lastly riding style. 29 mountain bike tyres usually 18 20 psi.
