WHAT SIZE ARE MY TYRES?
On the sidewall of a tyre you will find some markings. The list below will help you to understand that information on the sidewall. Some cars have different sizes front to rear.
HOW TO READ A TYRE
Look on the side of your tyre. You will find something like 195/60R15 88H. The numbers will vary according to your particular size.
195 - This is the tyre width in millimeters.
60 - The aspect ratio as a % (the height of the sidewall divided by the tyre’s width).
R - Denotes the tyre’s construction type – in this case it’s a radial.
15 - This is the rim diameter in inches.
88 - This is the load rating of the tyre.
H - This is the speed rating of the tyre.
Run flats – This will be written on the sidewall. Varies from diferent manufacturers. RFT, DSST, SSR or RUN FLAT will be written.
