275/55R19 tire size: dimensions explained

Factory size on the Mercedes-Benz G-Class (G 550 / AMG G 63). Below are the dimensions calculated from the size marking itself. Your vehicle's correct size, load index and speed rating are on the placard in the driver's door jamb; check it before buying.

Calculated values: diameter = wheel + 2 × (width × aspect ratio). Real tires vary slightly by brand and model.

Reading the marking

275 is the section width in millimetres, 55 is the sidewall height as a percentage of that width, R means radial construction, and 19 is the wheel diameter in inches. A passenger (P or Euro-metric) tire and an LT tire in the same size are not interchangeable without checking load requirements.
