Tyre size explained
“205” indicates the section width of a tyre in millimetres.
Aspect Ratio or Profile: “45” is a tyre’s aspect ratio or profile, 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 40% of its width.
“R” means that the tyre has radial ply construction. Most car tyres are constructed this way, so you will rarely find a car tyre without an R.
“16” indicates the diameter of the wheel rim in inches. So if you are buying wheels for existing tyres, this is the size you will require.
“83” is a code indicating the maximum load capacity of the tyre.
“V” is a code indicating the speed at which a tyre can be safely operated, subject to the tyre being in good condition, correctly fitted, and with the recommended inflation pressure. See the speed symbol table for car tyre speed symbol ratings.
