Tires from ancient wood/iron
gorgeously transformed into rubber

Let’s not forget the five
Tires to cars = shoes to humans
Its importance is self-evident
The factory tires are like school uniforms
Considering price and fuel consumption
The equipment must be small and beautiful .

Can OEM tires take you anywhere?
But it will be a little uncomfortable!
Although the current infrastructure of the motherland is very fast
But barren mountain roads, dirt country roads
The original factory tire blowout index is still very high

You have to master some tire knowledge first

Tips for changing tires
Generally speaking, tires need to be replaced every 4-5 years or 60,000-80,000 kilometers , whichever comes first.
Many people never change the tires until the car is scrapped, which is very unhealthy~ Remember the date of manufacture of the tires and replace them on time.
Always pay attention to the tire wear indicator . The height of the indicator is generally 1.6mm . If the pattern is flush with the indicator, or almost there, it must be replaced, otherwise the risk is great!
1. It is best to change the tires in the same group at the front and back. For example, if you want to change the left front wheel, it is best to change the right front wheel as well, because this will not cause differences in friction between the two sides due to the difference between the old and the new;
2. In addition to modification, do not easily change tires with different wheel diameters, because if the driving computer sensor does not update the tire data, there will be inaccurate speedometer, inaccurate fuel consumption, and even ESP failure, which will pose a safety hazard.
The more wear-resistant the tire, the better?
The more wear-resistant the tire is, the longer it can be used theoretically and the more economical it is. At first glance, it seems that there is no problem in pursuing the “wear-resistant index”.
but! A wear index that is too high will sacrifice other properties of the tire . Replacement of tires with a high wear-resistant index may produce greater noise and feel more bumpy when the vehicle is running.
Tires also need “regular maintenance”
In daily use of the car, it is necessary to pay attention to the tire pressure of the car. If the tire pressure is too low, it is easy to cause tire deformation, excessive deformation on both sides of the tire wall, wear on the shoulders of the crown, and the temperature of the tire will rise more easily, reducing the service life of the tire; The unit pressure increases, and the wear of the center of the crown increases, which also reduces tire life and affects comfort.
Some drivers adjust tire pressure according to the season. In fact, for most vehicles, the car manufacturer will give a relatively standard tire pressure parameter, which is usually posted on the inside of the cab door (near the B-pillar), on the nameplate or fuel tank cap, or in the vehicle user manual. Just refer to it directly. If the manufacturer has no special regulations, no special adjustments are required in winter and summer.
Regularly changing the position of the tire is also one of the secrets to extending the life of the tire. For example, the front wheels of some front-wheel drive vehicles bear 60%-70% of the braking force, which is more prone to wear than the rear wheels. Regular tire rotation can ensure that the wear of the four tires is consistent.
How to choose AT tires?
Do you still need to think about it? Of course, it is the off-road king of the tire industry – BFGoodrich ~ Our platform happens to be the official BFGoodrich dealer, and the information can be found on the official website~ Its classic KO2 tires (with snow function) are equivalent to AT tires , no fear of anything The terrain is most suitable for self-driving tour enthusiasts!
I have BFGoodrich, do I still need snow chains? !

Changing tires is a big science. If you want to change tires, it is best to change them to the same specifications as the original factory . If it is necessary to change, it is best not to change other parameters except the section width , and the section width can only be fine-tuned, otherwise you have to change the wheel hub.
Assuming that the original factory uses 235/70 R17 tires, let’s take this tire model as an example:
R17 means that the original car uses 17-inch wheels . If you buy a tire for 18-inch wheels, the direct result is that the inner diameter of the tire is too large, and the wheel is too small to be installed; what about changing to 16-inch tires? If the wheel hub is too big, the tire is too small and it will definitely not fit in, so the wheel hub size cannot be changed!
If the flat ratio is changed to 70 (flat ratio = tire wall height / tread width * 100%) and the tire width remains unchanged, the thickness of the tire will change, whether it is thinner or thicker, the circumference of the entire wheel and diameter will change.
Generally speaking, the speed of the vehicle is calculated by the rotation speed of the wheels. In the same way, if the circumference changes, the rolling distance of the wheel will change. If the flatness ratio changes slightly, the circumference of the wheel should change greatly. If this is the case, the speedometer on the car will be inaccurate. ?
The speedometer is “going faster” which is ok
If you “walk slowly” the ticket is not far from you!
However, if the section width is only widened to 235 , and the range is half to one level (5 is half level), this range is applicable to cars and SUVs , and generally there will be no major problems, and the resulting speedometer Errors (generally 1%-2%) are also allowed.
If your favorite car is a hard-core off-road vehicle such as Wrangler and BJ40, the width of the section can be increased by half to one level to the width of the SUV, that is, the width of the section is 235+20=255.
When the boss of our big BOSS installed BFGoodrich for the guards
It is based on the original factory tire section width of 235 plus three levels
That is 235+30=265
If you want to choose a section width over three levels
This involves modification
It is recommended to chat with the modification master first.
