Flate Rate

The rate of tire section height and tire section width.The same flate rate tire noted by ‘serie’,such as 55 serie.

Section Width

Tire total width reduce the words thickness on the tire side wall.

Speed Rating

The maximum speed of tire can drive under the specified situation.

Load Index

The maximum load ability of tire can bear under specified situation.

2. Tire Function

Tire can support the weight of automobile body and buffer the shock and vibration from road surface only after be matched with rim and be inflated.

3.Tire Maintenance

Tire Store

Please store tire at the place avoid sunshine,rain,oil and heating,prevent tire from corrosion maturing.

Tire Transposition

For the installation position is different per tire,and the force is different,the tire abrasion is also nonuniform per tire.In order to warranty the safty and increase tire using life,to assurance tire normal using,it’s better to do the work of tire transposition when tire drives per 8,000kms to 10,000kms. 

4. Tyre Choice

1)If you live in rainy area 

The braking distance will depend on the tire characteristics. The tread will drain out the water while driving, which will provide more grip and traction. You are suggested to select tires according to the follow standards:

The pattern design with good drainage ability

The “water holding capacity” is growing in direct proportion to the ratio of groove and trench. The figure and direction of the pattern will drain out the water to the side faces.

Anti-slippery compound

Tire manufacturers recommend using silicone anti slippery tread to resist the slipping on wet road.

For now, all the Sentury tires are classified with EU labeling, marking the wet grip, gas saving and noisy level, so that you will be convenient to choose your needed products.

Tip of Sentury：

It will need more distance to stop the car if equipped with worn tires on wet road. Besides, there is a big chance that aquaplaning may happen as well.

2) If you are living in dry and rainless area. 

If you are living in dry and rainless area. The precise maneuverability and agility will be the key factors to consider. The harder the pattern is, the more precise the maneuverability will be. Our suggestion to choose tires is as below:

Low ratio of groove/trench

The lower the ratio of groove/trench is, the bigger area the tire can touch the ground , which will enhance the gripping ability.

The wide and hard tread

The wide and hard tread is capable to reduce the movement of thick pattern

Tip of Sentury:

Compared with the wet road, it's safer to drive on the dry ground. However, careful driving is still recommended, since the gripping ability will be receded if running from asphalt to gravelly road.

3)If you are in cold and snowy area 

If you are in cold and snowy area, the braking distance on icy road depends on the quality of winter tires. Generally if the temperature is lower than 7℃, the tire will become rigid to effect the gripping force. The advantages of winter tire are as below:

The pattern of winter tire is more dedicated, which can penetrate the water films formed by the melting snow. It can also absorb the water film in an extent, which will cause better friction and gripping power.

The pattern of the winter tire is deeper. The snow is not easy to stuff in. The contacting area is widenso that the gripping capability is improved.

The rubber of winter is softer. The contacting area will spread under pressure, so that the snow can be extruded out. What's more, the road surface could be very bumping on under icy and snow conditions. Compared with normal tires, the bigger contacting area of winter tires with softer materials can be more stable while running on the bumping road.

Tip of Sentury:

You must not drive over-speed even if adopted the winter tires. Please control your speed according to the road situation.
