The Best Guide to Reading Tyres: Mobile Tyre Fitting London

Your car’s performance and safety are greatly dependent on its tyres. However, it can be difficult to decipher the mysterious markings and codes on your tyres. Don’t worry! The secrets to reading a tyre will be revealed in this blog, equipping you with the expertise you need to choose your tyres wisely. Understanding your tyres is crucial for a comfortable and secure ride, according to Mobile Tyre Fitting London.

Every tyre has writing, and numbers engraved on the sidewalls that provide information about the tyre’s size, brand, and manufacturing date. While many of the symbols on your tyres are not relevant to you as the driver, others are crucial to know when it comes time to replace your tyres.

Although 24hr Mobile Tyre Fitting London is always available to help you determine your tyre size and dimensions, it’s advantageous to learn how to do it yourself. By using this information to compare tyre prices online, you can be sure to get the best deal.

Tyre Width:

The width in millimetres is indicated by the first three numbers on the sidewalls of your tyre.

Let us imagine “225/50R17 95W” is the engraving on the tyre.

The number 225 is the width in millimetres meaning that the tyre will measure exactly 225 millimetres from one sidewall to the other.

Aspect Ratio/ Tyre Profile:

Following the width digits is the fourth as well as the fifth digit. In this case of the example before “225/50R17 95W”, the 4th and 5th digit would be “50”. These display the tyre’s height as proportion of its width. In this instance, the profile, also referred to as the “aspect ratio”, is “50”, meaning that the tyre height is equal to 50% of the tyre width.

Construction/ Tyre Radial:

“225/50R17 95W”

Radial tyres are those that have the letter “R” after the aspect ratio digits. This indicates that they are composed of cord plies that are angled forward by 90 degrees. In today’s world, most tyres are produced using this method because it gives the tyre added strength.

Furthermore, you can see the cross-ply construction type represented by the letter B written on a number of tyres. The most common type of tyre is R.

Tyres Rim Diameter:

The measurement of the wheel rim where the tyre can fit is indicated by the two numerals positioned after the R (on a radial tyre).  It measures in inches and indicates the rim’s diameter or height. In the example “225/50R17 95W”, the tyre is marked “17” which tells us that it can fit onto a 17-inch wheel rim.

Tyre’s Load Index:

“225/50R17 95W”

There are two additional digits, in this case, “95”, following the first two that represent the tyre’s diameter. You can use these figures to determine the maximum load capacity in kilogrammes of your tyre. If the tyre’s load index is “95”, it means that a maximum load of 690 kg can be carried by the tyre. Using a look-up table, the load index is converted to load in kilogrammes.

Tyres Speed Rating:

“225/50R17 95W”

You can find out your tyre’s speed rating by looking at the final number in this series of numbers and letters. This enables you to determine the top speed for a tyre that is properly inflated and carrying a load.  If you are unsure about the speed, feel more than free to contact us and talk to a helper at 24-Hour Mobile Tyre Fitting London. In this case, it is “W”, which means it has a maximum speed capability of 270 km/h. A random example is “Q” which when you search up or talk to a professional will tell you it has a maximum speed capability of 160 km/h.

*It’s crucial to keep in mind that even though you’ll never travel at the maximum speed permitted by your tyres, you should always use the right speed rating for your car. A higher rating can be fitted, but a lower rating cannot. In the event of a car crash, your insurance could become invalidated if you don’t fit an appropriate rating.
