What do tire numbers mean? A handy guide for drivers

The numbers and symbols on your tires provide essential information about your vehicle’s safety and performance. For example, the label 255/55 R19 111V means:

1. Width (255) – The tire’s width in millimeters. Here, it is 255 mm.
2. Aspect ratio (55) – The ratio of the tire’s height to its width, expressed as a percentage. 55 means the height is 55% of the width.
3. "R" symbol – Indicates radial construction (the most common type).
4. Rim diameter (19) – The diameter of the wheel rim in inches. In this case, it is 19 inches (48 cm).
5. Load index (111) – The tire’s maximum load capacity, here 1,090 kg.
6. Speed index (V) – The maximum speed the tire can handle, in this case, 240 km/h.

What happens if you choose the wrong tire size?

• Loss of balance.
• Increased fuel consumption.
• Longer braking distance.

Correct tires enhance safety. Ensure that the tires you choose match your vehicle’s specifications. If you’re unsure, visit an ASKO branch where experts can recommend the best option for your car.
