Actually, tire wear to/from the track is almost irrelevant since the Toyo RR's heat cycle out prior to actually wearing out of tread.
What this means is that the tires lose grip through repeated heating and cooling cycles and at some point will have lost enough grip as to not be able to turn competitive lap times so they can't be used for racing if the driver wants to be at the front. Freeway driving doesn't get the tire hot enough to count as a heat cycle.
After a couple of weekends racing, most racers will move that set to practice-only duty while bringing a new set to racing duty. When the second new set moves to practice duty, then the original set typically ends up in the dumpster (with usable tread still on the tire).
Some racers even use a new set of tires every weekend which makes the process of racing-practice-dumpster progress even faster. This might be overkill for some tracks but there certainly are tracks where you need brand new tires to be competitive.
Now, there are some racers who have won races on tires with a lot of heat cycles. It can be done, but is highly driver and track dependent.
