What do the numbers in tire size refer to?

Answer:
The big numbers refer to the size of the tire, rim size, tire height and width, as well as load rating (for example, "LT" refers to Light Truck duty)
Other (smaller) numbers refer to manufacture date, operating temperature, tire wear expectation and other information about the tire.
