What is the normal tire pressure for a scooter?
2 Answers
Scooter tire pressure normal range: The front tire pressure should be maintained at 2.0 bar, and the rear tire pressure should be maintained at 2.5 bar. Hazards of over-inflation: Tire friction and adhesion will decrease, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening tire lifespan; Increases body vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts. Hazards of under-inflation: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, negatively impacting driving safety; Increases movement of tire components, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to blowouts; Increases tire deformation, leading to cracks on the sidewalls and excessive heat generation from flexing, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
I've been riding scooters for several years and have some thoughts on tire pressure. Generally, the front tire pressure should be around 1.8-2.2 bar, while the rear tire is best between 2.0-2.5 bar. You should check your owner's manual for specific values, as different models like electric or gas-powered ones may vary slightly. I remember last time when the tire pressure was too low, the handlebars wobbled while riding, making it feel unstable. It wasn't until a friend reminded me that I went to the repair shop to check and refill the air. Too high tire pressure isn't good either - it causes faster tire wear and significantly reduces comfort. Now I check the pressure monthly with a tire gauge and always carry a portable inflator, which gives me peace of mind on long trips. If the tire pressure is out of the normal range, cornering control decreases, and it's easier to skid in rainy weather - definitely not a trivial matter.
