Keys to tire wear are a balanced tune, meaning little over or understeer leading to even tire wear front and back, softer brakes, and smooth driving. Almost any tune will provide good tire wear if you are smooth and the car is balanced. I've had cars tuned for long races with exceptional tire wear, given them to other people, and they complain up and down about how crappy the tire wear is, even if I win the race running away. The answer is not in the tune, it's mostly in the driving style. And giving up a few tenths on a shorter track or a second or more on larger tracks will go a long way to adding entire laps to the life of your tires.
