Common problem
The mention of tire pressure, they may think of 120PSI highway party, the party who will think of 60PSI mountain. But these two data is how come, the more detailed knowledge do you understand? It doesn"t matter. You"ll understand it after reading this article!
What is PSI always talking about?
It"s a unit of pressure. The tire, the international commonly used several units of measurement are the following:
BAR （BA）
KPA （kPa）
PSI （lb/in2, pound / square inch）
The conversion relationship between them is:
1 BAR=102 KPA=14.5 PSI
[knowledge] about riding bicycle tire pressure, you know?
The tire pressure unit on bicycles is often represented by PSI, while BAR is often used on tires, such as automobiles.
Then the general tire pressure should be maintained at what the right?
Tire pressure is not a fixed value
For the occupation drivers, different types of games, different conditions, different models, there are corresponding tire pressure values; for us ordinary riding friends, of course, do not need to be so complicated, how to do?
[knowledge] about riding bicycle tire pressure, you know?
Each tire on the tire of it will be marked with the maximum value, the maximum tire pressure value minus 10-20psi, basically can be used as a daily.
Tire pressure reference value, but in the face of different road conditions, there will be some corresponding changes:
In winter, the pavement is dry;
The rainy season, the road is wet and slippery; rainy days need to lower, increase adhesion to prevent slipping;
Road bump.
[knowledge] about riding bicycle tire pressure, you know?
Under these conditions, the tire pressure should be slightly higher:
Asphalt road
The tire Road （Yi dirty, gravel, broken fragments of glass that is most likely to lead to a puncture）
[knowledge] about riding bicycle tire pressure, you know?
The level of the tire pressure will produce what effect?
Low tire pressure
A better cushioning effect, because the inside and outside tires can produce greater deformation amplitude, can absorb more vibration
The rolling resistance increased, which is why you will cause fetal down the feeling of riding a laborious
The Yi tire and tire, especially for road vehicles
High tire pressure
The more bumpy, because of the high pressure tyre can absorb vibration reduction
The rolling resistance will reduce, riding a lighter, more agile response
