How tall is a 215 tire


Helpful Tire Info - BUDNIK

Our chart shows the overall section width, the outside diameter, the sidewall height and the recommended rim width range.

If your car requires something unique, start with picking the tire for the end of the car that is the most difficult.

If you’ve mini-tubbed the rear for example, and are going to run a big tire with less brand/tread/size choices, start by figuring out that size and what your options are. Then see if the those tire manufacturers also make a matching tire for your front.

We’ve included the sidewall height of the tire as a quick way to make sure your front tire doesn’t have a taller sidewall than your rear tire when doing staggered sizes. That’s usually not a good look.

There is a recommended rim width range for any given tire size with the ideal width usually around the middle of that spread. Some things to consider are how much sidewall bulge you want to see and most importantly, how wheel width affects the tires ride, handling and wear characteristics.

For grip and even wear the wheel width needs to allow for a good contact patch where the tread meets the pavement.

A wider wheel tends to make the tire more responsive to steering inputs but also taken to extremes can make the ride harsh because the sidewall doesn’t flex as easily.

A narrower wheel can give up some of that responsive handling and will tend to give a softer ride because the sidewall has more curve that flexes more easily.

Tire profile height: what is it?. Car tires TD KAMA of Russia

1. What is the tire profile height and how to calculate it?

2. What does the tire profile affect?

3. Increasing the tire profile: pros and cons

4. Reducing the tire profile: pros and cons

5. Do I need to change the profile height?

The tire profile is one of the key parameters that you need to pay attention to when choosing car tires. For each car, the manufacturer usually develops recommendations regarding what tire size should be and what deviations in these dimensions are acceptable. Deviations from the specified especially often concern the height of the tire profile. What affects the profile of the tire, and is it really necessary to change it? We understand.

What is tire profile height and how to calculate it?

Simply put, the height of a tire profile is practically its thickness, that is, the distance from the disk to the outermost surface of the tread.


The catch is that in the markings on the car tire itself, the profile height is not indicated directly in millimeters - it depends on the width of the tire.

For example, the marking says that we have a tire of dimension:

215/50 R17

The width is 215 mm, the profile height is 50% of this width, which means: 215 * 0.5 = 107.5 mm. What is important in this system of calculation? That with different tire widths with the same height percentage, the height will actually be different. So, for 225/50 tires, the profile height will already be 225 * 0.5 = 112.5 mm. So don't let the coincidence of the numbers after the fractional line on the marking mislead you - with different widths, the height will also be different.

Marking R17 in colloquial speech is often called the radius of the wheel, but this is not true. R stands for radial construction (how the cord fits in the tire), and the number is the fit or inner diameter of the tire in inches. So, we have 17-inch radial tires.

The labeling of American car tires is different from European ones. It is presented in the form

35×12.50 R15

There is no profile height data here, and all dimensions are measured in inches. 35 inches is the outer diameter of the tire, 12.50 is the width of the tire, and R15 is the already familiar 15 inches of the landing diameter. To calculate the profile, we connect geometry to arithmetic: subtract the inner diameter from the outer diameter, we get the “thickness” of the tire on both sides of the disk, divide it by two and get the profile. (35-15)/2= 10 inches. You can convert to meters according to the scheme 1 inch = 2.54 cm. Thus, the tire profile is 25.4 cm or 254 mm.

What is the profile of a tire?

As practice shows, even a slight deviation from the tire parameters specified by the manufacturer can affect how the car behaves on the road. For example, tires with a low profile and larger rims are easier to handle in turns, and a high tire profile increases flotation. It turns out that even with small changes in the height of the profile, you can slightly adapt the car to your driving style and road conditions.

How far you can deviate from the optimal dimension is another question. It is possible to reduce and increase the profile of the tire without changing the diameters of the wheel; it is enough to choose a larger or smaller disk, respectively. If the entire diameter of the tire increases, then problems may arise: when driving, the tire will touch the wheel arch or fender liner, which threatens with damage. And the wheel itself will become noticeably heavier, which will put an additional load on the suspension. Such changes are well tolerated by SUVs, since they are designed for additional load, but owners of ordinary passenger cars should think again.

Increasing the tire profile: pros and cons

Pros:

- while maintaining the width of the tire, a slight increase in the profile will make driving softer, especially when passing obstacles;

- reduces the risk of tire sidewall puncture;

- tires with a larger diameter (by 1-2 sizes) give a higher fit, which increases the patency of the tire.

Minuses:

- too high a tire profile will have a bad effect on braking and cornering performance;

- with an increase in the diameter of the tire, there is a risk of touching the body parts with tires, especially when the steering wheel is fully turned;

- Tires with a high profile weigh more, which gives an additional load on the suspension and the tires themselves when driving.

Tire profile reduction: pros and cons

Reducing the tire profile is not so often resorted to. This is usually due to the desire to give the car a more stylish and aggressive look. Tires with a low profile and a wide rim are usually reserved for sports cars and high-end cars with a sporty slant. And not in vain.

Pros:

- low-profile tires improve the car's responsiveness to handling and braking performance;

- tires with a low profile are more resistant to deformation during maneuvers and cornering;

- better grip on flat roads.

Minuses:

- low-profile tires are demanding on the quality of the road, since driving comfort on such tires drops sharply on uneven bumpy surfaces;

- tires with a low profile are noisier;

- the risk of deformation during long-term parking due to high pressure and an increased contact patch of the tire with the surface.

Do I need to change the height of the profile? conclusions

1. Low-profile tires are adapted to high-speed driving on highways and flat highways; they are unlikely to show their best side on domestic roads.

2. Increasing the profile of the tire while maintaining the diameter of the disk increases the vehicle's cross-country ability; an increase in the profile with a corresponding reduction in the disc increases driving comfort on rough roads.

3. Manufacturers advise deviating from the recommended tire profile sizes by no more than 3% for passenger cars. For trucks and light trucks, the spread can be more flexible.

4. Changing the tire profile affects how your car behaves on the road. Responsiveness, softness of movement, acceleration and braking speed and many other characteristics will change, which will have to get used to again.

what does the marking mean and how to choose a replacement?

It is not always easy for a motorist, who is faced with the replacement of rubber, to choose tires for his car. It's one thing if he knows what to buy, where to look and the product is in stock. Another - if there are no tires you need, you have to look for a replacement. How to do it?

First, you can use the tire calculator. This is the easiest option. Secondly, you can figure out by what principle rubber is selected in order to understand the mechanics themselves. This is the most viable option. Using the example of R16 215 55 tires, let's consider what other size they can be changed to.

These tires are in demand on many cars: new (Geely Emgrand, Opel Zafira, Chevrolet Cruze) and older (Mercedes Benz E-class 1993-2001, Peugeot 406 and others). The information will be relevant for the owners of these cars.

How to choose replacement tires R16 215 55

There are two parameters to consider when looking for a replacement. This is the outer diameter of the wheel and the width of the tire. They can be obtained from the marking R16 215 55:

  • 16 is the diameter (not the radius) of the disc that the tire is attached to. The value is in inches, converted to millimeters: 16 x 25.4 \u003d 406.4 mm.
  • 215 - tire width, already in millimeters.
  • 55 - tire height, measured as a percentage of the width. We consider: 215 x 55% \u003d 118.25 mm.

We got the width, we consider the outer diameter. It will be equal to the diameter of the disc plus twice the height of the tire: 406.4 + 2 x 118.25 = 642.9 mm.

How can I tell if a different rubber can be used? It is necessary to calculate the same parameters for a new tire and compare them with the dimensions for R16 215 55. If the difference between the widths is up to 10 mm, and between the wheel diameters up to 7–0 mm, everything is fine, you can use a new tire.

For example, let's take R17 225 55 rubber and try to compare whether it can be used instead of R16 215 55. Let's calculate all the parameters mentioned above:

  • Disc diameter - 17 x 25.4 = 431.8mm.
  • Tire width - 225 mm.
  • Tire height - 225 x 55% = 123.75 mm.
  • The outer diameter of the wheel is 431.8 + 2 x 123.75 = 679.3 mm.

For old tire width 215 mm, wheel diameter 642.9 mm. For the new one - respectively 225 mm and 679.3 mm. Width difference is 10mm, normal. The difference in diameters is 36.4 mm. This is a lot, it is better not to put such rubber instead of "native".

And what will happen if you put it?

The second wheel is higher than the first. It can touch body parts. But this is not the most important thing. Such a wheel will "deceive" the speedometer. For a unit of time, it will run a greater distance than the “native”, and the device will not take this into account. Therefore, it will show an underestimated speed.

The car owner will not be able to control this. There is a risk of becoming a violator of the speed limit, because the traffic police radars record the actual speed. Therefore, it is not recommended to install wheels larger than the diameter provided by the manufacturer on a car.
