Recommended Road Bike Tire Pressure

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.

Recommended road bike tire pressure. If your recommended tire pressure is near the maximum pressure rating for the rim we recommend moving up in tire volume. 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 example 90psi in a 25mm tire will feel the same as roughly 70 psi in a 28mm tire. These two extremes however represent only the upper and lower pressure limits.

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. 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. In drizzly or rainy weather also lower the pressure by 10 psi for improved traction. Remember as tire size and therefore volume increase you can decrease tire pressure.

Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. Road tires typically require 80 to 130 psi pounds.
