In the evolution of tires it has become necessary to better describe the tires in use. Before the internet became saturated with tire information, people in the industry knew what a tire size was without complete instructions. About 5-7 years ago a more formal tire description was introduced. When reading newer information that includes tires size descriptions you will find them identified as "designated size". A tire's designated size is like these two examples. ST225/75R15 or LT235/85R16 are designated sizes. The prefix is part of that size designation thus, it includes a design. Those two designs have their load capacities described by the load range lettering system.
The size designation becomes a factor when complying with the replacement tire selection recommendations to use tires like the OE tires. A well trained tire installer is not going to replace a ST tire with a LT tire, even of the same physical size.
