Do You Know How to Read Tire Sizes? 🤔🚗

Car tires play a crucial role in driving safety, handling, and fuel efficiency. Choosing the right tire is essential to maintain your vehicle's performance and ensure a comfortable ride. And to do that, you must first understand how to read tire sizes properly.

At Tyreportal.az, we explain the meaning of tire size markings in a clear and simple way. Let’s take an example:
215/55 R17 94W

🔹 📏 Width – Indicates the width of the tire in millimeters.
This number shows the part of the tire that touches the road.
Example: 215 = 215 mm
Wider tires offer better road grip but may increase fuel consumption.

🔹 📐 Height – The height of the sidewall, shown as a percentage of the width.
This indicates the tire’s profile height.
Example: 55 = 55% of 215 mm = approx. 118 mm
Higher profiles offer more comfort; lower profiles give a sportier look.

🔹 ⚙️ Diameter – Shows the diameter of the wheel the tire fits on, in inches.
Example: R17 = 17 inches
You must choose a tire that matches your car’s rim diameter. Wrong size can damage the car.

🔹 ⚖️ Load Index – Indicates the maximum load the tire can carry.
Example: 94 = 670 kg
You should choose a load index that suits your car’s weight.

🔹 🚀 Speed Index – Shows the maximum speed the tire is allowed to support.
Example: W = 270 km/h
For high-speed driving, the correct speed index is essential.

Why Is It Important to Read Tire Sizes Correctly?
Incorrect tire sizes can negatively affect steering, grip, braking, and fuel efficiency. Choosing tires that match the manufacturer’s recommended specifications is always safer and more effective.
