Understanding the LT235/80R17 E size

In the size code 235/80R17, 235 is the section width in millimetres (about 9.3"). 80 is the aspect ratio — the sidewall height is 80% of the width, or roughly 188 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 31.8".

The load index 120 means each tire supports up to 3,086 lbs — about 12,344 lbs across a full set of four. The speed symbol R certifies the tire to 106 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.
