The harm of low tyre pressure for a long time
Tyre pressure is too little for a long time, the contact between the tyre and the ground will be increased, will produce overheating, so that the service life of the tyre will be reduced, you will find that if your tyres for a long time "not enough air", whether will soon "bald".
On the other hand, cycling with low tire pressure will have poor texture, and even the control will be affected, especially in the corner, the whole car will be thrown out of the feeling, it is very easy to cause safety risks.
Moreover, the tire pressure is low to catch the ground area to increase, the oil consumption will be larger than the normal tire pressure, perhaps many motorcycle friends feel their car "not enough gas" will become very "big food".
The harm of high tyre pressure for a long time
The tire tire pressure is too high, the tire itself of the shock absorption travel light is shorter, thus reducing the ride comfort. In short, if the tire pressure is high, the car will become very bumpy when driving, reducing comfort and leading to safety risks.
On the other hand, the tyre pressure is too high, the contact area with the ground is reduced, reduce the proper grip of the tyre itself, in rainy days or bad weather riding, easy to cause sideslip or even roll over.
Method of determining the appropriate tire pressure
Different models of motorcycles, the tire pressure is different, and the front, rear and single, double driving, the required tire pressure is not the same, but it is generally impossible to adjust the tire pressure every single or double driving.
A bit more professional according to the barometer and tire pressure above the tire to judge, with the family motorcycle for example, 125 displacement about straddle and bay beam front tires about 2.25 rear tires about 2.75, pedal front tires is about 2.00 rear tires about 2.50.
Observe the information above the tire, according to the tire specific reference value to pump.
If not so professional, is usually at home in their own tire air, you can use both hands to press the tire, the tire only sag 2,3 millimeters can be the front wheel pressure sag 3,4 millimeters can be.
Motorcycle tire pressure should be checked every once in a while, "less air is added, air is put", but it is worth noting that the winter tire pressure will be reduced, should pay more attention to whether the tire pressure is enough, and remember that the rear wheel tire pressure is higher than the front wheel, the front wheel tire pressure can be appropriately less.
