Hi Metro,
I would agree 100%!
All of the coast down tests I did showed that it's not hard at all to get very inconsistent results, even on the same stretch of road.
I really appreciate your testing, along with Jim's and take it for what it is.
Even the coast down test inside the factory does not consider tire warm up, and I am not privy to what affect that would have on the overall outcome of their testing.
It *might* be possible, at least in the summer time, to get an idea of just how much heat is put into the tire carcass during normal driving, and that would be,
to take very careful tire pressure measurements of tires, both before driving the car and after driving on a controlled route.
I know that motorcycle race teams routinely check tire pressure buildup to determine the proper cold tire pressures before a race and keep notes of this throughout the season.
Jim.
