Understanding the LT305/55R20 E size

In the size code 305/55R20, 305 is the section width in millimetres (about 12"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 167.8 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 33.2".

The load index 121 means each tire supports up to 3,197 lbs — about 12,788 lbs across a full set of four. The speed symbol S certifies the tire to 112 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.
