Everything About Tyre Sizes: How to Choose the Right Tyre for Your Car?

The biggest confusion when buying a new tyre is the complex combination of numbers and letters written on its sidewall. Many drivers simply search for "teker olculeri" or "təkər ölçüləri" on the internet to figure out what fits their vehicle. Choosing the wrong size not only degrades your suspension system prematurely but also drastically increases fuel consumption.

The team at tyreportal az has put together this comprehensive guide to break down the secret codes of tyre sizes so you won’t be misled during your next online order or shop visit.

1. Decoding the Tyre Size: What Do the Numbers Mean?

Let’s take the most common size as an example: 205/55 R16 91V. These numbers dictate your vehicle's road behavior:

• 205 (Width / En): The width of the tyre measured in millimeters from sidewall to sidewall. This represents the contact patch with the road.

• 55 (Height / Aspect Ratio): The height of the tyre profile expressed as a percentage of its width (55% of 205 mm). Lower numbers indicate a "low profile" tyre, which sharpens steering but makes the ride stiffer.

• R (Radial): Indicates the internal structural design of the tyre (nearly all modern passenger cars use Radial tyres).

• 16 (Radius / Diameter): The wheel rim diameter measured in inches. While drivers in Azerbaijan colloquially call this the Radius, it technically stands for the full rim diameter.

⚠️ Critical Search Fact: Most drivers use unaccented terms like "teker en hundurluk radius" or "teker olculeri cedveli" when looking up information. Knowing these parameters protects you from purchasing the wrong product.

2. Load and Speed Index: The Hidden Safety Details

The markings written right next to the size, such as 91V, are crucial for your safety:

• 91 (Load Index): Indicates the maximum weight a single tyre can support (e.g., an index of 91 means 615 kg per tyre).

• V (Speed Index): Represents the maximum safe speed allowed for this tyre (e.g., V = 240 km/h, H = 210 km/h, Y = 300 km/h).

If you are buying premium high-performance models from Yokohama, Pirelli, Bridgestone, or Michelin, making sure the speed index matches your car's capability is essential.

3. Going Beyond Factory Specifications: Common Mistakes

Many drivers in Baku deviate from the official təkər ölçüləri recommended by the manufacturer to make the car look taller or protect the rims from potholes (e.g., installing 205/60 R16 instead of 205/55 R16). This results in:

1. Speedometer Errors: Because the overall diameter changes, your dashboard speed won't match your actual speed.

2. Friction Issues: When turning the steering wheel fully, the tyre rubs against the inner plastic fender liners, damaging the rubber.

3. Suspension Strain: The heavier wheel weight puts extra stress on wheel bearings and suspension components, wearing them down early.

Whether you choose budget-friendly options like Sailun, Lassa, Envoy, and Vitour, or premium choices like Continental, Hankook, and Goodyear, always stick to the official factory sizes listed on your car's door jamb or fuel cap.
