165/50 R15 Measurements

165/50 R15 tyres are original equipment on the Daihatsu Copen. The '165' designates the tyre's width in millimetres. The '50' is the aspect ratio which indicates the sidewall is 50% of the width (165mm) or 82mm. 'R15' indicates it is a radial tyre that fits on a 15-inch rim. The Copen has a sidewall that is short giving it less of a cushion to absorb the bumps. At Tyres.co.uk we have 165/50 R15 tyres available.
