205/50 R17 tyres are used by various compact and mid-sized cars. The relatively large rim size makes them suitable for sporty-looking vehicles, while the sidewall height is sufficient for adequate comfort. The first number in this description stands for cross-section width – here, the distance between sidewalls is 205 millimetres.
Following this, we have the aspect ratio indication – the number 50, which is a percentual value. This tells us that the height of the sidewall is 50% of cross-section width. This is an average value, situated just above those of low-profile. Sidewall or cross-section height is the distance from the tread line to the rim line.
The ‘R’ in the description indicates this tyre’s constructive type – this is a radial tyre, as the vast majority of tyres for cars and various other commercial vehicles are. Also note the final number, 17. This is very important, as it lets us know that this tyre is only compatible with 17 inch rims.
