In addition to the brand, every car tire also has a tire size on it. This tire size is made up of several codes, making it difficult for many people to understand. Below we have made an understandable story of the tire size, supported by a tire size chart. These tire Size Charts work for motorized vehicles like cars, busses, RVs, tractors, trucks etc… The tire size is made up of 7 factors:
- Vehicle Type
- the width of the tire
- Aspec ratio of the tire (or height of the tire)
- Construction of tire
- the rim size
- the load capacity
- speed rating index.

Tires size reading explained
Tire Size Chart – Width of the tire
The width of the tire is shown in mm (millimeters). In the example above, the number 195 can be seen. This means that the tire is 195 mm wide. The width of the tire can vary from 125 mm to 335 mm. The width always goes in steps of 10 mm. Tire sizes range from 125-135-145-155-165-175-185-195-205-215-225-235, etc. The tire width of the average middle class car is 205 mm wide.
Tire Size Chart – Height of the tire
Height of car tire In the tire size, the number that comes after the width of the tire (2nd part) is the height of the tire which is a percentage of the width of the tire. In the example above that number is 55. This means that the height of the tire is 55% of the width of the tire, which in this example is 195 mm. The calculation is easy by multiplying the width of the tire (195) by 0.55. You then arrive at 107.25 mm
Tire Size Chart – Tire Type
The tire type is in almost all cases indicated with the letter R. R stands for Radial. Radial explains how the tire was made. With a Radial tire, steel cord plies are applied perpendicular to the direction of rotation, so in the width of the tire. This makes the tire very flexible and maintains contact with the road surface when cornering. The counterpart of the Radial tire is the Diagonal tire. With the Diagonal band, the cord layers are placed diagonally over the band.
Tire Size Chart – Rim size
The rim size is the size of the rim around which the tire fits exactly. This is the inner size of the car tire and the outer size of the rim. Rim size is almost always given in inches. The unit of measure “Inches” is widely used in English-speaking countries and is indicated by the symbol “which we see as a quotation mark. One inch equals 2.54 cm.
Smaller cars are more likely to have a smaller rim size than larger cars. A larger rim fits wider tires which are necessary for better road holding and can also handle a higher weight. Nowadays, cars are increasingly equipped with larger rims (15 ″ / 16 ″ / 17 “) because this is not only more beautiful and sporty, but also because the tires are more common, which makes them cheaper. There used to be a lot of cars driving around with 13 inches and 14 inches. Today that is 15 inches, 16 inches 17 inches.
Tire Size Chart – Load capacity
load capacity code The load capacity of a car tire is displayed in a code. This code consists of 2 digits. In our example it says 87. According to the table, the code 87 stands for 545 KG. This means that this tire can carry a weight of 545 KG without breaking down. This is sufficient for an average passenger car. This would be too little for a van. Even if the sample tire would fit around the rim of a van, the tire is not suitable for the application. In the table below you can see the codes that correspond to the weight in KG.
Tires Sizing Chart – Speed rating
The speed index is a letter code that follows immediately after the wire power (2 digits). The speed index tells what the maximum speed of the tire is.
In our example 195/55 R16 87V, the letter V is the speed code. The letter V stands for 240 Km p / h. This is the maximum speed that the tire is allowed. Driving faster can therefore lead to dangerous situations.
In the table below, all letter codes of the speed index are shown with the corresponding maximum speed.

Tires Sizing and Running direction
The direction of tire rotation: What is independent of the tire size is the direction of rotation. Some tires have an arrow on the side of the tire. This arrow indicates the direction of rotation / running direction of the tire. The arrow must always point towards the front of the car. Tires with a V profile have at least an arrow and therefore also a running direction. Pay attention to this when mounting the tire or when changing a wheel. The steering and driving behavior can be directly influenced by incorrect mounting.
