Understanding the LT225/75R16 E size

In the size code 225/75R16, 225 is the section width in millimetres (about 8.9"). 75 is the aspect ratio — the sidewall height is 75% of the width, or roughly 168.8 mm. R16 means radial construction on a 16-inch wheel, giving an approximate overall diameter of 29.3".

The load index 115 means each tire supports up to 2,679 lbs — about 10,716 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.

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.
