There are thousands of car parts, tires for traffic safety which has a self-evident importance, travel usually checks the condition of the tires, it is because in the process of moving situations such as tire blowout event , improper handling it is easy to threaten the safety of the occupants, but for the size of the tires and how much our awareness.
1. Data on the tire
of the tire is fitted on a variety of vehicles or machinery ground rolling annular elastomeric article. It is typically mounted on a metal rim, capable of supporting the vehicle body, buffering external impact, and achieve contact with the road performance of the vehicle to ensure driving. So tires for vehicles can drive safely have a great and decisive role, we often see on the tire marked with some numbers, such as 185 / 65R is the tire width 185mm 15 77H which 185 represented 70 represents the cross section of a flat tire percentage ratio is 65, or a percentage of the section height 70 width. And R15 represents the size of the tire, i.e., a diameter of 15 inches. 77H, refers review index 77, the allowable vehicle speed is H.
2. tire performance
The main role of the tire is to support the vehicle full weight, need to withstand the car load, while passing other direction forces and moments; process with the need to ensure good adhesion between the wheel and the road surface, easy to improve the vehicle’s mobility, and by braking resistance; automotive suspension together with an impact relaxation when cars are subjected, and damping vibrations arising therefrom; automotive components being prevented from severe vibration and early failure, suitable for high speed performance of the vehicle during travel and reduce noise, to ensure the driving safety, driving stability, comfort and energy economy.
performance of the tire has a tread width of the tread height, determined three dimension, which affect the tire width grip tire width greater the stronger the grip, because a larger contact area with the ground, the resistance also becomes large in the case of strengthening the grip, it will affect the power and acceleration of the vehicle. Tread height is determined by the filter shock force greater sense of shock and manipulate turn, tread thicker absorption in the car feel smaller the volatility, will be more comfortable, equally thick tire will reduce cornering accurateResistance, but also it will affect the steering feel, so a number of high performance sports cars and car tires generally thin.
3 small tire
Due to the small size of the tire to aspects of data generally low, it is possible during running directly feel slow start, turn not precise , over bumpy roads the car feel more obvious, large and small tire tire did not look beautiful. So we often see some of the low allocation models using small tires, but with the high and low distribution models with models than the large tires, such as the relatively high sales volume Buick Hideo, with low tire models use the 195/65 R15 , and 205/55 R16 tires used on the vehicle is equipped with a high, but the data on the vehicle body are the same size. .
4 large tires
a small tire change bigger What are the benefits: First, can certainly improve steering capability, improving steering accuracy, improve steering feel; secondly large tires have a greater ground area than smaller tires can improve tire grip in the process of moving, strengthen the overall sense of control on the road, and finally the appearance of a large tire more dynamic, more stylish.
So we have to change the tires, then you can be promoted from two aspects:
1 is to keep the specifications of original equipment tires but we replace some of the higher tire brand tire, so that you can improve the quality of the tires, such as tread pattern more beautiful, better drainage, a smaller rolling noise, or more grip and so on.
2. Within the range of permissible performance car, the original car tire specification upgrade up, that is, to increase the tire size. Thus in addition to improving grip addition, of course, also make the vehicle change the tire overall look better, more atmosphere. And for a big tire at the same time, the quality of the tires will be higher.
In general, when buying a car, if the manufacturers provide different specifications in the same vehicle configuration, in the case of the financial capability of the proposed purchase of tire sizes than large models. For some friends want to improve vehicle performance, more it is to choose the same specifications, but the brand is betterTire to enhance the driving experience. Even worse if you want to change the tire size, be sure to ask around or 4S shop mechanic friend who, after considering the affordability of the car, go to select the appropriate size, or blind modifications may make the driver feel becomes .
