From load indexes to speed classifications, constructions to aspect proportions, a plethora of tyre terminology is to determine a tyre’s capabilities and suitability. These figures indicate the size, load endurance, and maximum speed of the tyre. Learning these abbreviations can assist you in selecting the ideal pair of Michelin Tyres Reading for your car and driving style.


Consider a few factors:

Load Index

The load index of a tyre indicates its maximal carrying capability. It is essential to purchasing a new tyre that meets the manufacturer’s specifications. The load index of the present tyre is present on the sidewall next to the diameter.

Speed Index

The speed rating specifies the maximum allowed speed for proper inflation and loading tyre. The speed rating of your tyres is on the sidewall and symbolic by a letter. For instance, a tyre with a speed classification of V has a top speed of 240km/h. When purchasing new tyres, it is crucial to match their speed category with the vehicle’s top speed.

Pressure Information for Tyres

This is the tyre optimum inflation condition, which is essential to know when monitoring tyre pressure. Consult the vehicle’s owner’s handbook and tyre placard for optimum inflation pressure instructions.


In the car’s owner handbook, the tyre size advisable by the manufacturer will be present. This guidebook should provide all the information you need to make a proper tyre purchase. In addition to the tyre placard, which is often on the inside of the driver’s door frame, a tyre placard may additionally provide tyre size data. Typically, the tyre placard will include both the tyre size and the appropriate tyre pressure.

Alternatively, a coding system is present into the sidewall of tyres. This enables you to comprehend their technological capabilities, enabling you to drive effectively on the basis of the sort of tyre you have. It will also assist you to select which tyre you should change it with when the time comes.


When it comes to maintaining road safety, tyres are some of the most essential vehicle elements. Regardless of whether you are steering, stopping, or sliding, they are in the centre of the process. This is the only portion of your car that truly makes contact with the ground. Consequently, it is vital to change tyres correctly.

Enter, tyre marks. These are to identify the dimensions and physical characteristics of a tyre, allowing you to locate a replacement that is compatible with your vehicle. Although a few of these tyre marks are unimportant, the majority have a substantial impact on efficiency and safety, so it’s vital to get them correctly.


Let’s examine the indicators for reading tyres:

  • The primary tyre size specification is in the large, strong characters on the sides of your vehicle’s tyres. For reference, if your tyre has a label 205/56 R16 91W, the 205 specifies the width of your tyre in millimetres, from sidewall to walls.
  • The number 56 thereafter determines the aspect ratio, which is as a percentage. The value represents the cross-section proportion of the tyre, which compares the segment height to the width. Here 56 indicates that the height is 56% of the full width of the tyre.
  • The “R” represents the Radial layout, following the 16-inch diameter of the tyre.
  • Consequently, the number 91 in this tyre measurement represents the load index, which corresponds to the maximum weight-bearing capability of this tyre. Whenever with proper pumping to the specified level, 91 claims that a tyre can support up to 615 kg of weight. Currently, in an effort to simplify matters, several manufacturers have begun to list weight in kilos.


It is not usually advisable to replace all four tyres on a vehicle. Sometimes, one or two of your tyres may need a change before the others. An expert technician will be able to determine which tyres are still usable and which must change immediately.

If you do not need to replace the tyres immediately, you may be willing to wait for a lower price. Check with local tyre retailers about any upcoming discounts or seasonal promotions. Comparing prices is an additional straightforward method of saving money. Once you have determined the sort of tyre you need, call three or four businesses to get an average price. Then it is time to negotiate the best deal!


Let’s examine a couple of considerations:

Tyre Pressure Information

This is the tyre’s maximum inflation value. Consult the owner’s handbook for further information on optimal tyre pressure, since it might affect your vehicle’s control, turning, stopping, and fuel economy.

Wear Indications on Tyres

The letters “TWI” indicate the position of the tread wear sensors on the tyre. Inspect these signs often to ensure that your tyres have sufficient tread. In the majority of EU nations, the minimum tread depth is 1.6 mm.

Production Date

This four-digit number indicates the week and year of your tyre’s production.


While tyres may seem to be identical rubber circles, each one is distinct. Upon confirming a reservation, it is vital that you double-check the marks on your Car Tyres Reading. If you fail to do so, you may purchase tyres that are unsuitable for your car and so cannot have an installation. When in dispute, always contact helpful advisors for assistance and guidance.
