Tyre size is an alphanumeric code that represents structural and dimensional details of tyres London. You can find these codes in the tyre's sidewalls.
Let's understand this even better through example.
Suppose a tyre size code is 175/70 R13. Then with the help of this alphanumerical code, we can decode the following:
175
These first three digits indicate the tyre's width, measured in millimetres.
70
After the tyre width comes the number 70, representing the aspect ratio of a tyre or a profile height measured in percentage.
R
Letter "R" explains that this tyre has radial construction. Apart from this, there are other types of tyre constructions, such as Bias Belt and Diagonal Cross-ply indicated by the letters B and D.
13
It represents the tyre diameter measured in inches.
However, there are other factors too which are very important to remember like:
