Tire size - mass delusions and reality

  • Tire size - mass delusions and reality

Very often one hears phrases like: “What wheel radius do you have, fifteenth?” Or “I have a radius of 16, but I’ll put the seventeenth for the winter so that the car is taller” . .. Such words can be heard both from the lips of people who are far from cars, and from “as it were professionals”, such as tire workers or sales managers in a car dealership .

Some things sound boring and hard to remember, but you need to know them. Especially for car enthusiasts. Especially those who consider themselves experts and have their own opinion on any occasion. The devil is in the details, and this article is about one such detail.

Not available with radius bar

A lot of people don't even understand what I'm getting at. “Well, radius, so what? I have wheels 195-65R15, radius 15, everything is written, what are you trying to be smart about ?! Here's what I'm thinking. R15 has nothing to do with radius. Neither R nor 15.


Now on the Internet you can find a lot of information, only such trifles as the marking of car tires are not among the most popular. We better discuss engine power or the number of "buns" in the cabin, right? And we will leave the choice of wheels to the manager in the store. Or ask a friend. He definitely knows! He already has a third car!

In fact, it won’t hurt to understand these boring numbers even just for general development. Moreover, this will help save money and influence the behavior of the car, but more on that later. So far - pure educational program, so that later you can understand each other well.

So, 195/65R15. Classic case. Squat down next to your car. The first number is the width of the running part of the tire, roughly speaking, the width of the tread. Expressed in millimeters. That is 195 mm. is the width of your wheel. With the understanding of this number, most of the problems are not.

Through a fraction, 65 is the value of the profile. Expressed as a percentage of the width. Not in millimeters! The profile is the part of the tire that sticks out above the rim. Sidewall. That is, the height of this sidewall will be 195x65% = 125.75 mm. Not 65mm. And not something else. Moreover, it clearly follows from this scheme that the height of 65% with a width of 195 will be one, and if the tire is marked (conditionally) 225/65R15, it will be completely different! 225x65% = 146.25 mm. Although the numbers 65 are the same!



R stands for the radial construction of the tire, or rather, the way the metal cord is laid inside it. The tire design used to be bias-ply, but that was a long time ago. Now you almost never see “diagonal” tires, they are all completely radial, and the letter R will not tell anyone anything new, it will only cause disputes about the notorious radius ...

And finally, the number 15. This is the diameter. The diameter of the landing part of the tire, the inner diameter, the part that is in contact with the disk. Expressed in inches. 1 inch \u003d 2.54 cm. That is, 15x2.54 \u003d 38.1 cm This is also the outer diameter of the disk, if someone has not guessed ...

Which tires can and can't be fitted?

And then the fun begins. We can play with these numbers if we want to put other tires (rims) on the car. Ideally, the main thing is that the overall diameter does not differ, or differs slightly. Example.

The wheel 195 / 65R15 has the following overall diameter: 38.1 cm - inside, plus 125.75 mm x2 \u003d 251.5 mm (there is a profile both above and below). Converting to centimeters for simplicity, we get 38.1 cm + 25.15 cm = 63.25 cm. That's how! This is the total wheel diameter.

Now, if you want to put other wheels on, the owner of the car must understand the following: automakers understand this figure in the same way as we do. Given the diameter of the wheel, the suspension, brake system and body are designed. Therefore, for the same car model (for example, for the Volkswagen Polo sedan), three wheel sizes are officially allowed. The simplest version is content with 175/70R14 (overall diameter 60.06 cm), 185/60R15 (60.3 cm) and 195/55R15 (59.55 cm).

It turns out that the “wheel by 14” is MORE, albeit slightly, than the wheel by 15 in the case of 195/55. This is to the question raised above, about how to put more wheels for the winter ... You need to carefully calculate everything. Will a larger diameter number also mean a larger wheel size overall? Not always.



By increasing the size of the disk, we must reduce the height of the profile, otherwise the wheel will simply start to cling to the arch, not to mention such more fundamental qualities as handling. Of course, the margin often remains and it happens that by “playing” with the tire width and profile height, you can really get a couple of millimeters of clearance without sacrificing anything else.

A simple calculation will show that within the same diameter - 14 - 175-70 and 185-65 and 205-60 are applicable, if there is a desire and an opportunity to put wider tires ... A car on wheels with a lower profile height will be controlled sharper and more accurately, but will inevitably suffer smooth running. And the safety of the discs may be in question, especially when they fall into a deep hole with sharp edges. A low profile will simply not be able to "absorb" the impact energy and it will go further - into the disk. Always keep this in mind when buying wheels and don't forget the simple truths.
