what it is, how to reduce wheel friction
In order for a car wheel to roll, it must overcome four forces: gravity, friction on the roadway, air resistance and rolling resistance. Up to 30% of a truck's engine power can be used to overcome these forces. For passenger cars, such losses are less, but even a relatively small decrease in this indicator leads to a decrease in fuel consumption and an increase in mileage on one tank.

During the rotation of the tire, is deformed in the contact patch with the road surface, and
this leads to the following consequences :
- deforming materials are heated, and part of the rolling energy is dissipated in the form of heat; nine0008
- Restoring the deformation of the sidewalls and tread blocks also consumes energy that could be used for useful work - the movement of the car;
- the area of contact with the coating increases - the friction force increases.
Since 2012, all tires sold in the European Union, were required to have a sticker , on which the fuel economy label was indicated with a color scale and letters from A (green) to G (red).
And the fuel efficiency of each class was measured by the coefficient of rolling resistance: for tires marked A, it is minimal (RR6.5), for tires marked G, it is maximum (RR12.1). nine0003
Since May 2021, the sticker has changed slightly, and now it contains not 7, but 5 classes from A to E. And the fuel consumption between neighboring classes has increased by approximately 0.1 l / 100 km compared to the previous version.
Help. The difference in fuel consumption of a passenger car with tires of the first and last class can be up to 0.5 l / 100 km (or 7.5% of the total).

What determines rolling resistance
Rolling is influenced by various factors. A significant part relates to the features of the tire itself and its condition:
- Construction and materials. Influence the degree of deformation in the contact patch and friction with the road surface.
- Speed index. Some solutions aimed at improving directional stability have a negative impact on economy.
- Seasonality. Winter tires ("Velcro") must provide maximum grip on wet and slippery roads, and a priori they cannot be more economical than summer ones. nine0008
- Bore diameter and profile height. The larger the overall diameter of the wheel, the lower the rolling resistance.
- Tread pattern. Fine and deep pattern increases the aerodynamic drag of the tyre. "Bald" old tires roll better than new ones.
- Pressure. The lower the tire pressure, the higher the rolling resistance.
External factors also affect rolling. These include:
- Pavement type. nine0024 Concrete and pavers have more resistance than asphalt. The soft primer is slightly squeezed and “dusty” under the weight of the car, which increases fuel consumption.
On gravel without bituminous impregnation, the wheels slip. - Road surface quality. Rough structure, potholes, pits, ruts - all this interferes with movement.
- Coating temperature. From 10°C to 40°C the rolling resistance decreases and then increases.
Rolling resistance coefficient calculation
The rolling resistance depends on the vehicle weight and the coefficient of friction with the road surface. The drag force in general is calculated by a simple formula:
P = Q * f ,
where f is the coefficient of friction.
Naturally, the coefficient of friction depends on the type of road surface and the type of propeller. And for machines with elastic tires, it is lower than that of tractors and all-terrain vehicles on caterpillar tracks, but higher than that of rail vehicles.
Attention! Tire rolling resistance coefficient can be called a complex conditional characteristic.
It is determined by the results of tests under certain conditions, and its value indicates how much force must be applied to a car of a certain mass so that it continues to move in a straight line.
The unit of this coefficient is expressed as enkg/t (kg/t). And if RR = 12, then this means that for every ton of a car, a force of 12 kg (approximately 120 N) must be applied to overcome the rolling resistance. nine0003
Good to read : Tire selection by size
Features of tires with reduced rolling resistance
To improve fuel efficiency, manufacturers use the following solutions: reduce tread height to reduce block creases; make the tread more rigid; is added to the composition of additives that increase the density and stability of the rubber mixture; nine0008 lighten the weight of the tire; optimize the tread pattern to reduce aerodynamic drag. But reducing rolling resistance is not an end in itself - test tests of "green" tires show that they usually have a longer braking distance than "red" tires.
Therefore, a balance of fuel efficiency and traction, economy and functionality is important.
Caution! For heavy vehicles, this issue is solved more easily than for passenger cars. For them, in addition to universal (U), each axle produces its own type of tires: steering (S-steer), leading (D-drive), free rolling (T-trailer). nine0003
Steering tires have a clear response when maneuvering, driving tires are responsible for traction and braking distance, free rolling - have a minimum coefficient of rolling resistance and are responsible for fuel economy.

Conclusion
Tires with a low rolling resistance not only save fuel for the owner, they also increase mileage and reduce exhaust emissions. And this ultimately reduces the harmful impact on the environment. nine0003

Articles about technical information and tire characteristics
Marking car tires for most car enthusiasts is not an easy task, since many are not familiar with the designations indicated on the outside of the rubber walls.
Meanwhile, the wheel diameter is a parameter with which you can choose tires for a car that meet the technical characteristics of the vehicle. These parameters are important when choosing summer or winter wheels, and during a scheduled tire change in order to improve individual machine characteristics. nine0003
Before choosing a car wheel diameter, it is important to understand what tire profile and rim offset are needed to obtain the recommended values for installation. To ensure the best handling, stability of the car on the road and high cross-country ability, it is necessary to select parameters that correspond to the technical regulations of the car, operating conditions.
Below is information about tire designation and construction, as well as how you can choose tires using a tire calculator. nine0003
What is the diameter and radius
Despite the large amount of information, designations on tires that the manufacturer indicates, many drivers confuse the radius of the wheels and the diameter, or even understand one parameter under different concepts. In practice, rubber manufacturers do not use the "radius" parameter, since it means the distance from the center of the tire to its edge. This wheel measurement is not used.
Tire manufacturers measure rim size in inches, so tire construction and rims are nothing more than a diameter. By it is meant the distance between opposite edges of the tires. Circumference is measured along a line through the center of the wheel. This parameter is used more often, since it is easily measured, and also shows the optimal values \u200b\u200ballowing you to accurately select a wheel or tire for any car.
Other indicators stand out:
- Bore diameter. Using these values, a valid rim parameter is selected for installing rubber. In order to avoid problems during the installation process, the bore diameter must have a permitted size and fit exactly to the disc. A difference of a few centimeters will not allow you to install the wheel due to possible tire damage.
- Outer diameter. In addition to the inner diameter, the outer diameter is also measured in tires. It represents the difference between opposite points located on the outer perimeter of the wheels. The parameter is measured by manufacturers according to a certain formula. The accuracy of the value determines how accurate the odometer reading will be. nine0008
It is worth noting that the letter R has nothing to do with the radius, as many people think. It indicates the type of tire - there are radial and diagonal models. The first, which are labeled R, differ in the structure of the frame.
Here the cord is stretched between the sides without overlapping threads. The elastic shell of the wheel is fitted with a special belt made of durable cord, which does not deform under load. This technology makes the design of tires durable, improves the grip of rubber on the road. nine0003
Bias tires have a similar tread, identical radius, but differ in thread connection. Unlike models marked R, here the threads in the structure are located diagonally between the sides. The belt layer, which holds and stabilizes the tires, is less stable during rolling, which leads to rapid tire wear.
What are the sizes
Manufacturers offer tire models with different parameters and radius. Depending on the type of car, drivers can choose between 13 and 20 diameter car wheels, as well as the rim width, which is measured in inches. There are significant differences between the models. They differ in profile height in centimeters, speed qualities, wear resistance.
Since it is not easy to measure which wheels will fit a car on your own, many automakers indicate the recommended wheel sizes on the car door pillar. nine0003
To install the wheels correctly, tires must be selected according to their size. This parameter is applied to the sidewall of the rubber in the following form: 225/45/R 18 84T. You can decipher the marking in the following way:
- 225 - the width of the rubber profile;
- 45 - profile height, calculated in relation to the tire width as a percentage;
- R 18 - the number indicates the diameter of the tire, the letter indicates the radial type of rubber;
nine0007 84 - parameter of the index and load factor that the wheel can withstand; - T - permissible speed index at which the car can be controlled.

Basic designations
Tire sizing is essential for safe driving. If you choose hub mounts, take into account the radius and height of the profile, you can ensure good vehicle stability on any road surface, ensure clear control and smooth running.
For best results, the rim width in inches should be in accordance with the manufacturer's recommendations. nine0003
On the side of any tire, you can find a combination of different markings, understanding which will help to obtain information about rubber and its properties. On the outside of tires, manufacturers indicate:
- Tire brand (model name). It implies a specific tread pattern, as well as technical parameters that distinguish it from competitors. Depending on the manufacturer, different markings are indicated on the surface, so the letters for different brands can mean different tires. nine0008
- Maximum tire load. The MAX LOAD parameter, which is indicated on the outside of the rubber, is measured in kilograms or English pounds. The maximum load is calculated for each wheel separately. It is incorrect to determine the difference in the total number of tires, since such values will turn out to be too high. This will adversely affect the safety of the structure.
- TREAD WEAR INDEX, traction index (TRACTION INDEX), and temperature index (TEMPERATURE INDEX). These parameters mean how stable the car will be on different roads and in different climatic conditions. nine0008
- Maximum allowable air pressure. The value is determined by the manufacturer in pounds, which are calculated per square inch.
- Regulatory compliance settings. These can be markings E17 (European standard) and DOT (American standard).
- M+S designation, which can be used to determine what a certain tire model is designed for. Depending on the type, the tires can be used in winter conditions or for driving in mud and wet snow. nine0008
- Permissible speed values. The tire speed index determines the maximum design speed at which you can drive on public roads. The difference in designation will affect the stability of the car on the road.
- Structural Values - Manufacturers indicate the number of breaker plies and carcass type as R.
