We did some tire testing w/ M/T engineers, some time ago.
[Article ended up in Chevy HP, as I recall.]
We used an I/R gun to determine the track temps.. [Waaay too hot for anyone w/ any sense to be there..Ambient was 104, track near 150]
Jerry Francis of M/T, was calling the shots.[I was the "tire geek", Dave Emanuel, [writer] was the BS'r]
To maintain some degree of repeatability, we heated the tires to track temp, + 10-15*. That took a short burnout, and an immediate stage.. NO dry hops! That leaves "bald spots", of rubber w/ little to zero oils, at the surface.
Back under my rock...
