Find your size on your tire

  • Look at the sidewall of any one of your tires and make note of the numbers and letters on it.
  • The information will allow you to research tires that fit your car.
  •  

What do these letters and numbers mean? 

Tire Width or Section Width - Width of the tire (or thickness) in millimetres is measured from a tire’s widest point of its outer sidewall to the widest point of its inner sidewall.

Aspect Ratio - Aspect ratio is the relationship between the tire’s sidewall height and the tire’s width. The lower the ratio, the smaller the sidewall height, which means better cornering, but a rougher ride.

Construction - This indicates the tire’s internal construction. They can be “Radial” like most tyres, or D, for “Diagonal construction” or B, for “Belted”.*

Wheel Diameter- The number is in inches and indicates the diameter of the wheel on which the tire is designed to fit.

Load Index

 

This indicates how much weight the tire is certified to carry at maximum safe inflation. Numbers refer to a chart that specify the load capacity that the tire can carry. For example 97 = 1,609 pounds

Speed Rating chart

This indicates the maximum safe speed at which a tire is certified to carry a load under specified conditions. Speed ratings range from A (lowest) to Y (highest), with one exception: H falls between U and V. To find the maximum speed for your tire, refer to the speed rating chart. Exceeding the lawful speed limit is neither recommended nor endorsed.

Find your tire size in your vehicle owner’s manual or on your car door

  • Find the information in your vehicle owner’s manual in the glove compartment or on the tire information sticker on your driver’s side door.
  • Usually those elements contain all the information relating to your tire size and specifications, as well as the appropriate tire pressure.

See the “Find your tire size on your tire” tab for a full description of the numbers and letters.

What are OE tires?

OE stands for “Original Equipment”, meaning that the tires were approved by your vehicle manufacturer to come standard on your vehicle.

Some vehicle manufacturers, such as Audi, BMW, Mercedes and others, equip their vehicles with tires that are specifically made for their brand. These tires have a special OE marking on the sidewall. In this case, Michelin recommends replacing the tires on your vehicle only with tires equipped with necessary OE marking.

Table of OE markings by vehicle brand:

 = BMW, Mini
MO = Mercedes
AO = Audi
VO = Volkswagen
N0, N1, N2, N3, N4 = Porsche
MO1 = AMG
RO1 = QUATTRO
