Understanding the LT245/75R16 E size

In the size code 245/75R16, 245 is the section width in millimetres (about 9.6"). 75 is the aspect ratio — the sidewall height is 75% of the width, or roughly 183.8 mm. R16 means radial construction on a 16-inch wheel, giving an approximate overall diameter of 30.5".

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 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.

What the Cooper Discoverer Stronghold AT is built for

The Cooper Discoverer Stronghold AT is an all-weather tire — a year-round option certified for severe snow service, so it can stay on the vehicle through winter. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. It is classified for all-terrain (a/t) use.
