A few years ago there was an article in Grass Roots titled "The Big Stick" (I think) by a track tire vender/consultant. He basically said that the tire temp data method of tuning was developed on open wheel, nylon belted or bias ply tires (can't remember which) and was less applicable to steel belted DOT radials running on closed fendered cars.
The reason being that the steel belts hold and conduct heat across the tire and the outside edge of the tire was more exposed to the cooling wind than the inside.
Don't shoot the messenger, just thought it was interesting.
