Understanding the 255/50R21 size
In the size code 255/50R21, 255 is the section width in millimetres (about 10"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 127.5 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 31".
The load index 109 means each tire supports up to 2,271 lbs — about 9,084 lbs across a full set of four. The speed symbol Y certifies the tire to 186 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.
