How To Read Tyre Sidewall Information

Lets take tyre below as a sample:

We'll take each value and see what it's all about
  • 205 - measures the tyre width in milimeters.
  • 55 - aspect ratio or height of the tyre itself from the width. Shown here is 55 means 55% from 205. We use this value to determine tyre profile. Low profile or high profile tyre.
  • R - Radial construction tyre. More info about radial tyre head to HERE
    • Click Here for other tyre types.
  • 16 - diameter of inner rim in inches.
  • 91 - Load rating of the tyre. See table below for full load rating. This number indicating the maximum load in KG that the tyre could withstand at the speed rating(see speed rating)
  • V - Speed rating. It indicates the maximum speed the tyre can withstand in conjunction with Load rating. See the speed rating table below.
