Is the wear rate really the same? I was one of the ones who started saying it is, but that may be based on fact all my drivers drive around at max relax in most races, as my cars are faster than opposition. I noticed that it didn't matter between tire types, they all ran out at same lap, with driver at full relax
So is wear the same if you make the drivers run at half way between hot & cold? Or at max stress?

Racing hards will last longer than mediums or softs as long as you aren't driving like a blind monkey. Racing hard and pushing the car will wear any tires much faster than they should. Softs will get gripier sooner but will wear quicker, hards take longer to get their full grip but will last longer. Of course other conditions apply, that do not apply in game such as weather temp, track surface composition, etc. As stated earlier, tire wear is over simplified for GT5.
