285/40 R20 rear tyres on the Mercedes-AMG GLC 63 are combined with a set of 255/45 R20 front tyres. To break down the first set of numbers, 285 represents width in millimetres, 40 is the aspect ratio which is 114mm (40% of 285mm), and R20 indicates radial construction on a 20-inch rim with an overall diameter of 736mm. In the GLC 63, the sidewall of this tyre provides better cushioning, compared to a lower profile tyre. Tyres.co.uk stocks 285/40 R20 including run-flats and XL versions.
