# How do you know if your bike has the proper tire pressure?

Contents

Every tire has a recommended psi printed on its side close to where it touches the rim. This is usually written as a range (for instance, “90 to 115 psi”) since there are reasons why you’d want to be on the higher or lower end, which we’ll get into shortly.

## How do I know if my bike tire has enough air?

Know the tire pressure you need

Before you pump, check the sidewall of your tire: It should list the pounds-per-square-inch (psi) range that your tire can safely handle. Typically, a road tire can go between 80 and 130 psi, while a mountain tire holds between 25 and 50 psi. Hybrids usually take between 40 and 70 psi.

## Why do bicycle tires lose air so fast?

Bike tyres are typically pumped from anywhere fron 5–10 bar (depending on type of bike.) Because of this pressure diffrential, air molecules flow out of your tube, not into it. This is the cause of the pressure loss. Some tubes, made out of latex and used by professionals, lose air even faster.

## What PSI should my road bike tires be?

Pump it up.

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 per square inch); mountain bike tires, 25 to 35 psi; and hybrid tires, 40 to 70 psi.

## Why does my bike tire keep losing air?

Road bike tires lose air for two main reasons: because rubber tires are porous and naturally allow air out through tiny pores, and because there’s an object in the tire or some other kind of wear that has made the tire susceptible to air loss. … Over time, bike tires will go flat when not used.

The standard tire is inflated to about 30 to 35 pounds per square inch. Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 5 psi. The burst pressure of a tire is about 200 psi.
