When choosing a new "footwear" for cars, it is important to understand how to choose the right wheels to the tires. You should consider many parameters of the wheel to avoid a dangerous situation on the road because of the bent rim or out of the bolt. The footprint is always calculated for a specific brand of car.
Before you deal with the question of how to choose the right wheels to the tires, should be clarified in the service: will not affect whether your action on the warranty. While self-selection of new wheels, which differ in construction from the standard, the manufacturer can take your machine with warranty and all repairs will have to pay out of pocket. It is better to inquire about all the allowed sizes of rim and tyre on your brand.
Most dealers exist in the sale of ready-made coupled models of wheels. They can tell you how to choose the right wheels to the tires, and show the method of calculation. It should be remembered that prices have to be much higher. It is better to deal with this issue on their own and choose what exactly you need.
If you still decided to change the wheel yourself, then consider how to choose the right wheels to the tires. First, the owners are determined with the type material of rim: forged, cast increasingly in demand. Heavier wheel is strictly not recommended, so compare the weight of the rim with the machine.
Tyre Size to the size of the drive should be matched in width. It would seem that it should be the same, it is clear and without recommendations. But the inner part of the rim chosen according to the formula: SH1=Ш2х(23%–30%), where SH1 – the desired value of the width of the rim, ø2 – the width of the tyre. Accordingly, the size of the rim gets smaller the tire by 25 or 30 %.

Here is an example of the calculation of the wheel rim according to the known parameters of the tire. Take the standard tires width 195 mm and will hold recruitment drives. The tire has always taken the top of a smaller disk. What is the limit to take 25 or 30 %, depending on the nearest standard values. That is, multiply 195 by 0.25 and 0.3 and get 48,75 and 58,5 mm.
According to the mapping table, which is often given in inches, we find the nearest value. It is more rational to choose a rim width of 5.5 inches, a size closest to the existing tire. Take a narrow rim is not recommended: there is a strong wear of the tread. This is due to the sagging rubber on the edges.
A Smaller bus width to the width of the disk will not work. Planting of rubber in the wheel is loose, making it impossible to use tubeless type of installation. With camera wheel will also continue to move sideways causing cracking or early failure of the wheel.
The Maximum load on the tire during rotation, there will be a gap cords with narrow or wider profile. The appearance of bumps or cracks in the sidewalls will be guaranteed. Lost lateral stiffness of the rubber. There are standard maximum deviation size:
Values greater than the specified range, reduce the main parameter driving – resistance. However, most security can be obtained only in full accordance to the size of the tire and rim.
There is a standard ratio of the tires to the rims. Common diameters of the disks 13, 14, 15, 16, 17. Already big values are for trucks. Automobile wheels are trying to increase when buying a new car.
Why increase the disk size? The answer is simple: it looks more aesthetically pleasing, large wheels are easier holes. But the main criterion for the selection of a larger diameter – the desire to put low-profile tires. It is more designed to speed and keeps the best side-load.
When replacing a high rubber low profile overall diameter of the wheel is not increased. Changing the size of the disk, and decreasing the thickness of the tire. However, the wheel should not change its weight, and therefore preferred are alloy instead of forged products. The latest models you need to choose carefully.
Choose the size and type of drive to the vehicle on the eyes is unacceptable. Rarely a person can see a deviation of 2 mm. And are versions of tires and wheels there are. Diameter center hole for mounting the wheel must match 100 %.
So, the models of different manufacturers having a diameter of 100 mm, there are analogs with dimensions of 98 mm. And often motorists turn a blind eye. This setup is invalid, over time, might be an emergency situation due to the destruction of the metal.
When designing a car the tolerances are assigned to the minimum in the plus side. That is a greater diameter at 1 mm from the docking allowed, but smaller are already strictly prohibited. This is because the tightening of the nuts will be differences. Only one of them will sit, as needed, the rest gradually unwind from vibration.
Among the many other dimensions of the disc are basic: the diameter of the Central hole, the wheel offsets, types of bolted connections. The first parameter, oddly enough, respectedmanufacturers of original products. The beautiful alloy wheels are often made universal, so the diameter can be more seats. You have to close your eyes for the original textures. To close the resulting gaps can sleeves and inserts, along with the proposed drive.
This parameter as the wheel offsets are measured relative to the plane of the mounting bolts. This size does not affect driveability. Positive departure allows you to create the bizarre shape of the wheel. However, there are limits that exceed not recommended by car manufacturers.
Bolting changed to the so-called anti-theft. A compound with a similar thread, but with a unique key. Without it, attackers will not be able to quickly remove the nice wheels. In order to protect your property to save on this not worth it. Also, the replacement of bolted connections happens if you change the flight of the disc. You will need to select the thread longer. And remember a simple rule: before you mount the tire on the rim, try the disc on the seat. It is often customary marriage stopping completely set the purchase on the seat.
