Is It Safe to Use Different Tyre Sizes on Your Car?

Dubai is renowned for two things: its towering skyscrapers and ultra-fast cars. Many drivers in the city enjoy taking their cars on adventurous journeys, exploring the urban landscape. To ensure these trips are hassle-free and pleasurable, it's crucial to have the right tyre sizes.

However, many drivers wonder if they can purchase tires online Dubai in various sizes. You might also be questioning whether it’s safe to drive with mismatched tyre sizes. In this blog, we’ll address all your questions about using different tyre sizes.

What Are The Different Ways In Which Tyre Sizes Can Differ?

Any car tyre doesn’t have just one way of measurement. You might not know this, but there are actually three ways in which you can measure a tyre: width, rim diameter, and sidewall aspect ratio.

When we write a tyre’s measurement, it’s something like this: 225/45R17, where 225 is the width, the sidewall aspect ratio is 45% of 225, and 17 is the rim diameter. Below, we will discuss these in detail:

1. Width:

   You can measure any tire by its width in millimetres. The front tyres in many vehicles have a lesser width than the ones in the back. For instance, the 1978 Lamborghini Countach had front tyres with a measurement of 205/50R15. On the other hand, the 345/35R15 back tyres had a comparatively larger width size.

2. Rim Diameter:

   The wheel rim diameter, also known as the internal diameter of the tyre is included in the tyre measurement. The example given earlier of the Lamborghini Countach had the same rim diameters in the front and back tyres. However, they can be different too in some vehicles like tractors, where the rear tyres have a higher rim diameter than the front tyres.

3. Sidewall Aspect Ratio

   The third key tyre measurement is the sidewall aspect ratio. You can measure a tyre’s sidewall aspect ratio by calculating its sidewall height as a percentage of the entire width of the tyre. Since this aspect ratio affects the diameter of the wheel, it must be consistent from side to side.
