Every so often you will need to know the tire size you are using to have it replaced or repaired. This ain’t always easy yet it should be because every tire you shop comes with the size indicated. You should be able to read it even on the current tires your car is using unless of course you’ve been using that pair for years!
Looking at the sidewall of your tire below, we have a series of numbers…let’s break them down!
205: This is the width or diameter of your tire in millimeters(mm).
55: This is the height of the tire sidewall as a percentage of the tire width: The bigger this value, the smaller the tire rim and the larger the sidewall.
R16: Diameter or width of the tire inner rim in inches. It is not a percentage!
R means that the tyre has radial ply construction, meaning the way in which it has been constructed. Most car tyres are constructed this way so you will rarely find a car tyre without an R.
91: This is a number representing the load rating of the tire. The number is obtained from the load rating index tables.
V: The maximum speed the tire should achieve at maximum load. This is the upper limit for safe operation.
These numbers are also associated with your vehicle registration number.
