This is an important requirement for tire safety and mileage. Your motorcycle owner’s manual will tell you the recommended cold inflation pressure. On some motorcycles, the recommended front and rear tire pressures will be different. The pressures stamped on the sidewall of the tire are only for maximum loads. On some occasions, these pressures will also be the manufacturers recommended settings as well. Riding on tires with too little air pressure is dangerous. The tires will build excessive heat. This can cause a sudden tire failure that could lead to serious personal injury or death. Under inflation may also: 1. Damage the tire leading to tire failure 2. Adversely affect vehicle cornering 3. Reduce tire life 4. Increase fuel consumption 5. Fatigue cracking
