21 INCHES Michelin TYRES FOR YOUR Car

Haven't figured out your tyre size yet? To choose the right MCHELIN(R) tyre size, open your vehicle owner’s manual or your driver’s side door: the tyre size of your car and load/speed rating information is there.

 How to read a tyre size?

For example, if you read 205/55R17 91V, it means:

  • 205 represents the width of the tyre (in millimetres)
  • 55 represents the height in comparison to the width in percentage
  • R is the type of construction (R for radial, D for diagonal and B for belted)
  • 17 is the wheel’s diameter (in inches)
  • 91 is the speed and load rating.
  • V represents the speed index defining the maximum speed at which the tyre can go

Michelin also develops OE (original equipment) tyres - tyres that are fitted to a car at the time of its manufacture. They indicate that careful attention has been paid to the tyre and model package to deliver the level of performance owners expect. For example, 'N'-marked MICHELIN tyres are specifically designed especially for Porsche, 'K'-marked tyres are specifically designed for Ferrari and 'T'-marked tyres are specifically designed for Tesla. Marked tyres designed for different car models are the fruit of research carried out jointly by Michelin engineers and their counterparts at the carmaker in question.

Keep in mind that knowing the correct tyre size is essential to minimize safety risks and achieve the best driving performance. Your tyre choice must also comply with the law and the recommendations of the vehicle manufacturer when replacing your tyres.

Michelin recommends the installation of identical 4 identical tyres on all 4 driving wheels of your vehicle (except if your vehicle is originally equipped with different dimensions, front and rear).

When searching by tyre size alone, please be aware that the displayed results may not be applicable (or recommended) for your vehicle due to several factors (including but not limited to size, speed rating, load capacity, intended service conditions, etc.). Please seek expert advice.
