Many small and compact passenger cars owners will be interested in 195/50 R15 tyres. No sure about what it actually means? Nothing could be simpler. The first indicator, the number 195, informs us that this tyre has a cross-section width of 195 millimetres. This is measured from sidewall to sidewall, with the tyre mounted, but not supporting weight.
The number 50 is the aspect ratio indicator. Aspect ratio expresses cross-section height (sidewall height from tread line to rim line) in relation to width. In this case, cross-section height is 50% of 195 mm (cross-section width). Using a percentual value is preferable because width indications are always approximate.
The final number, 15, stands for inner diameter - in practical terms, this tyre can only be fitted to a 15 inch rim. But we can also see a letter in this description, preceding the last number. The R' lets us know that this is a radial tyre, by far the most common constructive type for light vehicles today.
