For example: you have a 175/70 R13 wheel on your car. Using this table, we determine the profile height of your tire 175 by 70, we get 12.2 cm. If you want to put the tire wider and leave the wheel height the same, then select a value close to 12.2 from the table.
We get the size 205/60 R13. If you want to increase the size of the disk, leaving the wheel height the same, the following calculations are necessary: 175/70 R13 the profile of this wheel according to the table is 12.2 cm, multiply it by 2 because.
wheel height consists of two profile values 12.2x2=24.4 cm. Next, add the size of the disc, R13 is 13 inches, convert to cm. 13x2.54=33cm. Then add the two values 24.4+33=57.4cm. this is the full height of the wheel. Now, having done some simple calculations, you will understand that you can put 195/50 R15 or 185/60 R14, for these sizes, the wheel height is about the same - 57cm. But we should not forget that with an increase in the width of the tire, it is desirable to increase the width of the disk. Usually, the standard wheel height on the machine can be increased by 1, maximum 2 sizes. Before you change the dimension of the wheel, you can always consult with our highly experienced specialists. In some cases, the car has regular wheels of the same radius, but different widths, and the height of the wheels must be the same. (BMW 7 SERIES front 235/50 R 18, rear 255/45 R18). For all these calculations, this table was created.

In simple terms, tire profile height is the distance from the rim to the wheel tread surface.
Tire profile height in metric size is marked on the wheel as a value that indicates a percentage of tire width. For example, the dimension 215/65 R16 indicates that the height of the tire profile is 65% of the width of 215 mm and is 139.75 mm, with a wheel radius of 16 inches. The metric dimension is most common among the assortment of car tires in stores, so it will not be difficult to calculate the height of the tire profile.
To convert metric to inch: 1 inch = 2.54 cm.
Inch Tire Sizes do not show the profile height in the marking, the total wheel height, wheel width and tire radius in inches, eg 31x10.5 R15. Tire conversion from inches to metric. To calculate the metric profile height, it is necessary to subtract its radius from the total wheel height, divide the resulting value of the total tire profile height in half and get the profile height. (31-15): 2=8" profile height, now 8x2.54cm=20.32cm metric profile height.
As a rule, car manufacturers recommend the optimal tire size for each particular model and modification of the car, with the limits of possible deviations in size. However, practice shows that even going beyond these dimensions can improve the driving performance of the car for each specific case, depending on the operating conditions and the requirements of the owner. When changing the standard size of a tire, it is necessary to understand what the height of the tire profile affects in order to be prepared for changes in the behavior of the car and possible consequences.
By increasing or decreasing the profile of a tire, indicators such as stiffness, comfort, load and reliability change.
Increasing the tire profile within reasonable limits (1-2 sizes without increasing the width), the car will become softer and more comfortable, due to the larger diameter of the wheel, the car's landing will increase and its control will practically not worsen. If you exceed the allowable height of the profile, then the car will have a roll in control, deterioration in braking and cornering, due to an increase in the center of gravity and a crease of the rubber along the height of the profile, an increase in fuel consumption, possible grazing on the elements of the body and suspension at the moment of complete inversion of the steering wheel or at full load. And also, there will be an additional load on the chassis parts, which will reduce their service life.
Reducing the profile of a car tire without changing the width and radius will allow you to get better handling and improved braking.
The lower the rubber profile, the less comfort, the car becomes stiffer, the load on the chassis parts increases, the chances of a wheel breakdown from hitting the disk and disk breakage increase due to the reduced tire donut, fuel consumption increases due to a decrease in tire diameter (fixed by increasing the wheel radius ). Moving along the path of reducing the profile and increasing the radius to equalize the overall diameter of the wheel, fuel consumption will remain without an increase, however, the rest of the nuances of low-profile rubber operation will remain.
Car owners are recommended:
