Understanding tyre size made easy with these pointers from the tyre experts.

195 indicates the section width of a tyre in millimetres.

Aspect Ratio
65 is a tyre’s aspect ratio which is its height from the base of the tread to the rim. This number represents a percentage of the tread width. For example, the height of this tyre is 65% of its width. Low profile tyres have smaller aspect ratio percentages.

Tyre Construction
R means that the tyre has radial ply construction, meaning the way in which it has been constructed. Most passenger tyres are constructed this way so you will rarely find a car tyre without an R.

15 indicates the diameter of the wheel rim. So if you are buying wheels for existing tyres, this is the size in inches you will require.
