Correspondence of the sizes of tires and disks on passenger cars

The issue of selecting tires for disks has always been relevant for motorists, since every self-respecting driver needs to know certain parameters. If the characteristics are not known and these parameters are not followed, the car will experience a significant deterioration in performance, which seriously threatens safety.

In order to match rubber to the wheels as accurately as possible, you should first study the marking of the wheels:

Wheel marking with dimensions R13 4x98 ET35 J5 D58.6

It is the latter that plays a major role in matching tires and wheels. In order to choose the right wheels for tires on passenger cars, you can use the table compiled by the specialists of Avtotire Kom. Or you can use the selection of discs for the car by clicking on the link .

Tire sizes. Selection advice.

Home \ Useful \ Tire sizes. Selection advice.

Tire size is its main parameter.

For example, the inscription on the tire “205/55 R16”, means:
205 - tire width in mm
55 - profile height as a percentage of the width (i. e. 205x55% = 112.8 mm)
R - radial tire technology ( a common misconception is that it is a radius of )
16 - tire diameter in inches (16x25.4 = 406.4 mm)

The car manufacturer usually gives recommendations on tire selection. There can be several recommended tire sizes, each of which is guaranteed to fit the car without significant loss of handling, ride, speedometer readings and durability of the chassis elements.

For example, for a Hyundai ix 35 car, the manufacturer recommends the following tire sizes:
215/70 R16
215/60 R17
225/60 R17
235/55 R17
225/55 R18
235/50 R18

Accordingly, for R16, R17 and R18 - you need the appropriate disks, but this is a separate article.

We will conditionally accept that “215/70 R16” is the base tire size, and we will make a table of characteristics of all other tire sizes relative to the base:

Outer diam. , mm Profile height, mm Change in ground clearance, mm Speedometer readings, %
215/70 R16 708 151 0 0
215/60 R17 690 129 -9 +2.5
225/60 R17 702 135 -3 +0.8
235/55 R17 690 129 -9 +2.5
225/55 R18 705 124 -2 +0.4
235/50 R18 693 118 -8 +2.1

It can also be seen that a change in clearance by 10 mm, and a speedometer reading of 2.5% is within the normal range, and there is nothing wrong with that.

Please note that the profile height is indicated for new tires with a tread height of 8mm, and as the tread wears out, its diameter will decrease by 1-2%.

What if I supply tires that are not recommended by the manufacturer?

It is quite possible if you make a choice wisely!

Below is an example of replacing stock tires “195/60 R15” with “185/65 R15”. The table shows that with such a replacement, the width will decrease by 10 mm, and the height of the profile will increase by 3 mm. It is unlikely that anyone will feel such minimal changes in the behavior of the car.

Outer dia., mm Profile height, mm Change in ground clearance, mm Speedometer readings, %
195/60 R15 615 117 0 0
185/65 R15 621 120 -3 +1

Changing the tire width ±10mm, outer diameter from -10mm to +7mm does not lead to any negative consequences.

Changing the height of the tire profile.

With reducing the height of profile , the car's handling improves noticeably, reactions to the steering wheel become quick, clear. But at the same time, comfort worsens, the car becomes stiffer. These tires are suitable for drivers who prefer a sporty driving style.

And vice versa, when increases the height of profile , the reactions to control are more sluggish, slowed down, but the level of comfort is noticeably higher, shocks and vibrations are less transmitted to the body. The car gently overcomes road bumps. These tires are suitable for lovers of a relaxed driving style.

In general, you can reduce the tire profile to any extent, only if you want to “feel” every bump. There are restrictions in the direction of increasing the outer diameter of tires. Usually, without any difficulties, you can install tires, increasing the radius by 7-10 mm for cars, and by 10-20 mm for SUVs. With a larger increase, the tire may catch some elements of the chassis or body when driving.

Popular and rare tire sizes.

I will give an example from life.

The standard tire size for Chevrolet Lacetti is 195/55 R15. It is not clear what the engineers were thinking when developing this budget car and choosing tires of this size ...

Below is a table with similar sizes and prices. Prices are for the same brand and model of tires in the same store for comparison purposes only.

Outer diam., mm Profile height, mm Change in ground clearance, mm Speedometer readings, % Price, rub
195/55 R15 595 107 0 0 4170
185/60 R15 603 111 +4 -1.3 3610
195/60 R15 615 117 +10 -3. 4 3730
185/65 R15 621 120 +13 -4.4 3020

I know from personal experience that 185/65 R15 (the largest of the list) on the Lacetti does not hurt either front or rear, under any load, at any steering wheel turns and on any bumps.

There are rumors that there are special individuals who install 195 / 65R15 and even 205 / 65R15 on the Lacetti, but in this case they are already complaining about the grinding in corners, and naturally there is not enough engine thrust. the gear ratio has changed a lot from the regular one. Why they do it, I personally do not know.

Why is the price of similar sizes so different? All due to the fact that there are popular sizes that are produced in large quantities. The larger the volume of production, the lower the price. And there are rare sizes for which demand is low, they are produced in small batches, and the price for them is higher than for popular sizes.

Accordingly, following the example of the Lacetti, I can say that by installing 185 / 60R15 you can save a little at all without compromising handling, ride and acceleration dynamics. And if there is very little money, then it is quite possible to install 185 / 65R15 without serious consequences.

It is impossible to give examples for all cars, but sometimes there are options for switching to non-standard tire sizes that can be saved.

Not available in regular size tires

Another example. Hyundai Grand Starex h2 car, standard tire size - 215/65 R17, it is written on the plate of the door arch. The size is so rare that it is rather problematic to find it even in Moscow. What can we say about the regions. It's good that it can be replaced with 225/60 R17 or 225/65 R17. Accordingly, you can either underestimate by 5 mm, or raise by 6 mm. It seems to me that for a car of this class, it would be more preferable to raise and increase comfort.

Comparison table for replacement sizes for Grand Starex:

Outer diam., mm Profile height, mm Change in ground clearance, mm Speedometer readings, %
215/65 R17 712 140 0 0
225/60 R17 702 135 -5 +1.4
225/65 R17 724 146 +6 -1.7

Total

So, in what cases it is possible to install tires not recommended by the manufacturer.

  1. If you can't buy stock tires in your area
  2. If you want to intentionally change the ride and handling responses to suit your driving style.
  3. If you want to save money when buying a new set of tires by replacing the standard tire size with a cheaper, more common one.
