Do you have to use 18 inch wheels for the R18 on the tire?

Hello! First of all, it is recommended that the specifications of the tires purchased should be consistent with the specifications of the tires assembled in the original car, if you need to change the tire specifications, you must go to a professional tuning shop for tire upgrades, or consult the car manufacturer.

There are various factors to consider when modifying tires:

1.Local traffic regulations (will not affect the annual inspection of the vehicle, vehicle warranty, etc.);

2.speed and load index of the tire;

3.Rim specifications, such as width and offset, etc.;

4.Space; 5.the suspension system of the car;

6.The (important) load radius of the tyre remains the same;

Therefore, it is recommended that matters such as tire specification conversion and installation must be carried out by professionals. If necessary, consult the automobile manufacturer on relevant laws and regulations.

Yes, the tires must be selected according to the instructions.

In the past, wheel bearings for passenger cars were mostly used in pairs with single row tapered rollers or ball bearings. With the development of technology, sedans have widely used sedan wheel hub units. The range of use and usage of the hub bearing unit is growing day by day, and it has developed to the third generation:

The first generation consists of double row angular contact bearings. The second generation has a flange on the outer raceway for holding the bearings in place, which can be simply sleeved to the axle and fixed with a nut. It makes it easy to repair the car.

The third-generation hub bearing unit is a combination of the bearing unit and the anti-lock brake system. The hub unit is designed to have an inner flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together.

Yes, R stands for radial tire.

How big tires can 18-inch wheels be replaced, it should depend on how many inches the wheel width is, the tire width of normal 18-inch wheels is inches, and it is most suitable for using 225 mm wide tires, and the maximum can also be used 235 mm wide tires.

18-inch wheels, the width can reach 9 inches, suitable for the use of 255 mm wide tires, up to 265 mm, the middle and rear acceleration and braking performance of the vehicle have greater benefits, and wider wheels and tires are not suitable for civilian vehicles. And the fuel economy will also be greatly reduced, the frame and suspension strength of the original car may not be able to adapt to such a strong grip, which may lead to damage, and it must be cautious to replace the wide wheels.

Tire size

If you are not short of money, you can replace the wheels, the well-known lightweight wheels are made by forging technology, in fact, there is a kind of cliff technology to make the wheels, although the lightweight is slightly inferior, but compared to the original wheel carefully guess the hub, under the same size, at least 7 kg can be lightened, the lighter yellow mass can improve the starting speed of the car, daily use is more light, higher toughness is not easy to damage than the wide front type original wheel.

There are many ways to express the specifications of tires, and there are generally four common ones in the market, which are imperial, German, metric and American. It should be noted that the specifications of the tires purchased are recommended to be consistent with the tire specifications of the original car, if you need to change the tire specifications, you must go to a professional tuning shop for tire upgrades, or consult the car manufacturer.

17-inch wheels: 215 55R17; 18-inch wheels: 235 45R18.

In terms of appearance, there is still a big difference in the width of the two. The 18-inch wheels are flatter than the 17-inch wheels, with the 18-inch wheels being flatter, thinner and larger in diameter, giving them a more luxurious look.

Which is better, 17-inch or 18-inch wheels?

Because the 18-inch wheels are flatter, the tire wall is thinner, the contact area between the tire and the ground is larger, and the grip performance is better, especially in the wet and cornering, the lateral sway is reduced, the braking performance is more stable, and the safety is higher.

But at the same time, there are also disadvantages because the tire wall is thinner, the shock absorption function is reduced, and the comfort and quietness are reduced. Especially when the car is driving on uneven roads, the tire wall is easy to be damaged due to the thin tire wall, and even a tire burst will occur.

The increased contact area between the wheels and the ground will increase the drag of the car, making the car more fuel-efficient. Each type of wheel has its own advantages and disadvantages, so it is difficult to say which wheel is better, it can only depend on the individual car owner to see if the performance of the wheel is suitable for their driving habits.

In order to make the service life of the wheel hub longer, all car owners should carry out regular maintenance. For example, when there are stains and dirty oil on the wheel, it should be cleaned in time. At the same time, the car should not be in a humid place for a long time, so as not to rust the wheel, and the wheel hub can be waxed and maintained regularly.

Can be loaded.

According to the "Motor Vehicle Registration Regulations":

Article 17 In any of the following circumstances, the owner of a motor vehicle may change it on his own without affecting the safety and identification number plate:

1) Small and micro passenger vehicles are equipped with front and rear anti-collision devices;

2) Freight motor vehicles are equipped with draft shields, water tanks, tool boxes, spare tire racks, etc.;

3) Motor vehicles increase interior decoration, etc.

Hello, of course not, the size of the wheel must be consistent with the inner size of the tire, 17-inch wheels can only fit 17 tires.

No, the tire is a vacuum tire, and if the size is small, it can't be installed, and if the size is large, it won't fit. In that case, you won't be able to flush the tire pressure.

The hub size must match the inner tire size.

To 17 inches. The hub can fit 17

Generally refers to the 17, 18-inch wheels for inches, the two wheels are about centimeters apart in diameter, and the difference between the wheels lies in the parameters, whether they can be replaced with each other and the center distance offset hole distance is related, if the wheels are consistent with these parameters even if the size is different, they may be able to replace each other, but to ensure that the outer diameter of the tire under the different hubs is close to the need for a tire width and flat ratio of appropriate specifications.

17-inch wheels with 225 50 17R tires are more suitable.

Increasing the diameter of the tire has an impact on the odometer and speedometer, which will cause the value displayed by the car odometer and speedometer to be less than or greater than the actual value The speed of the automobile engine refers to the speed of the automobile flywheel, which is realized according to the reciprocating motion of the engine piston, and the flywheel of the automobile engine is connected with the axle of the wheel through the gearbox, and the rotation of the flywheel is transmitted to the axle of the wheel in proportion to the gearbox.

No.

If the tires of the 255 35 R18 can be installed on the 18* wheel, then the 225 40 R18 can be installed on this wheel, and the rim will be wide and the tires will be narrow, so it can't.

Take "18*8J" as an example, the diameter of the 18-finger rim is 18 inches (1 inch = centimeter The width of the rim is 8 inches, and J is the style code of the rim. That's easy to understand. The difference between 18*8J and 18*'s wheels is that the rim width is different, one is 8 inches and the other is inches.

Hello! Inquire about the national standard, 225 40 R18 specifications of tires, it is recommended to use the rim width is: 7 J, 8 J

Therefore, it is possible to use rims of different sizes, so please refer to the actual capacity. Generally, there will be rims on the tread label of new tires, and the width is recommended.

Rim size identification:

J Profile of the rim.

Not interchangeable.

There is only one difference, the tire speed class is different. R stands for this tyre, which allows the car to be used in a working condition of 170 km/h, and there are fewer tires of this specification now. The ZR stands for all high-speed tires that include a running capacity of more than 240 km/h.

The specifications of the original tires of the car are basically greater than or equal to the maximum electronic speed limit of the car.

Hello! Z = means that the maximum speed is higher than 240 km/h (it is the speed level, generally look at the data behind the tire specifications, for example: 205 55R16 91V, look at V).

It should be noted that tires of the same specification, structure, manufacturer and pattern should be equipped on the same axle. (Load index, speed level is the same).

Z is for high-speed tires and R is for radial tires. There is very little difference in China's road conditions, so don't worry. Don't save money on tires, just choose a first-line brand.

The zr level is the highest speed class, the r is the general level, if the car is traveling at high speeds, it is not interchangeable, and low speeds can.

The difference between the two is that the tire speed grade is different, R stands for the tire that allows the car to be used in a working condition of 170 kilometers per hour, and Zr stands for all high-speed tires that contain more than 240 kilometers per hour and more running capacity.

The tire speed grade refers to the maximum speed at which the specified load can be carried under the specified conditions. On the sidewall of different tires, English letters will be used to indicate the speed level of the tire. J, K, L, M, N, P, Q, R, S, T, U, H, V, W, Y, Z are the letters corresponding to the speed level of radial tires, where J to Y represent kilometers per hour, and Z represents more than 240 kilometers per hour.

Generally speaking, the lower the letter representing the tire speed grade, the better the performance of the tire, and the higher the **. When choosing tires, you should choose tires according to the manual, and only those that are suitable for the model are the best. (Photo by photo:.)

How many tires can be replaced with 18-inch wheels, it should depend on how many feet the total width of the wheel, everything is normal The tire width of the 18-inch wheel is inches, and the most suitable application is 225mm wide tires, and the larger can also be used 235mm wide tires. No matter how big it is, the 18-inch wheels can be 9 inches in total width, and the suitable application of 255mm wide tires and larger 265mm tires have more benefits for the rear section of the motor vehicle to accelerate and its brake pedal performance. There are also wider wheels and tires that are not suitable for civilian vehicles.

Some people may ask, is it true that the wider the wheels and tires, the better? In fact, no, wider tires, strong flip friction resistance, must have enough horsepower to promote everything normally, the daily development may slow down, and the rationality of gasoline and diesel will be greatly reduced, Changqiao original window frame and its suspension compressive strength may not be integrated into such a strong grip, may cause damage, dismantling the wide wheel hub must be cautious.

Here's a little common sense:

Grip that is too strong can be harmful for everyday use, but what else can be done to reliably improve performance? If you don't have a bad money, you can disassemble the wheels, the widely spread lightweight wheels are made by calcining technology, in fact, there is also a kind of cliff technical production of wheels, although the lightweight is slightly less than that, but compared with the original wheels, the same size, at least 7kg can be relieved above, the lighter yellow quality can improve the development rate of the car, the daily application is more cheerful, and the higher flexibility is not easy to destroy compared to the original wheels.
