What is the recommended tire pressure for scooters?

Motorcycle tire pressure is not absolutely related to the model or displacement of the vehicle, but rather depends on the tire's grade. Different grades of tires have different pressure requirements. Generally, for motorcycle tires, the front tire pressure should be maintained at 2.0 bar, and the rear tire pressure should be kept at 2.5 bar. Since the average pressure for car tires is around 2.2 bar, this reference value is relatively accurate. Below is some relevant information: Maximum pressure limit: Each tire has its maximum pressure limit. Exceeding this specified value can lead to the risk of a tire blowout, while insufficient pressure can cause premature tire damage. Therefore, tire pressure must be adjusted according to the maximum pressure value of the tire's grade. Typically, the maximum pressure for motorcycle tires is 280 kPa, which is approximately equal to 2.8 bar. Tire pressure measurement: Tire pressure should be measured using a dedicated pressure gauge, not by visual inspection or other methods, as these methods lack accuracy. A pressure gauge can clearly and accurately display the tire pressure, so it is essential to use a dedicated pressure gauge when measuring tire pressure.
Having ridden small scooters for over a decade, I've learned that tire pressure is something you really can't take lightly. For a typical 125cc scooter, the recommended front tire pressure is 2.0-2.2 bar, while the rear tire should be 2.2-2.5 bar for single riders, with an additional 0.2 bar when carrying a passenger for safety. Just last week, I helped a friend check his tire pressure and found his rear tire was down to 1.8 bar, with visible cracks on the tire sidewall. Always measure when the tires are cold, and in summer during long trips, it's better to keep the pressure 0.1-0.2 bar below the standard value to avoid blowouts from high temperatures. If your handlebars feel heavy or the bike feels unstable when cornering, it's likely due to incorrect tire pressure. When refueling, ask the attendant to check with a mechanical gauge for the most accurate reading—don't rely solely on electronic sensors.
As a commuter who travels 30km daily, I've found tire pressure has a huge impact on fuel efficiency! My 125cc scooter's factory specs recommend 2.0 bar front/2.2 bar rear, but I get better mileage at 2.2 front/2.4 rear when carrying a passenger with backpack. Once when pressure dropped to 1.5 bar, fuel consumption increased by 10% for the same distance. Recommendation: inflate to MAX marking on tire sidewall if available, otherwise follow vehicle placard specs. When summer road temperatures exceed 40°C, I proactively release 0.1 bar to prevent blowouts. The clearest sign of underinflation is squeaking tires when cornering - don't wait until steel belts show before replacing tires.
