Information
What is a wheel calculator
This is an online tool that allows you to calculate how the wheel dimensions, ground clearance, speedometer readings and other parameters of the car will change when changing tires to a different size. It also helps to choose the appropriate rims width for the selected tire.
When replacing rims and tires, taking into account the data of the tire calculator, it is important to measure several parameters yourself:
1. The distance from the suspension to the inside of the wheel and from the shock absorber cup to the tread ensures that the new wheel does not touch the suspension elements.
2. The distance from the wing and steering rods to the tread is to prevent the tire from contacting the body and steering elements. The size of the new tires and rims should not differ much from the regular ones in order to avoid problems with handling and safety.

Basic rules for replacing tires and rims
1. The tread depth of summer tires is usually 0.8–1 cm.
2. When increasing the diameter of the discs, reduce the reach: for each inch of diameter, reduce the reach by 3 mm.
3. Non-original discs may have a larger hub opening. Use special centering rings to fix them.
4. It is forbidden to drill holes in the discs or to grind the hub if the disc does not fit the size.
5. The tire calculator will help you choose the right wheels and keep the car manageable.
6. If you doubt compatibility, it is better to contact specialists.
