Randy, You are correct in my book. This idea shows up in race cars with tires of different compounds for different tracks. Sort of makes sense doesn't it. Carl
Carl is right, Michelin used to have tire engineers assigned to race teams in the now defunct American Le Mans Series that would pick the tires based on the driver, car, temperature, rain conditions and track....
The weight of cars, grades and curves all make a difference. Have pulled up to 135 car train with ABBA set of Life Like FA's. All cars were a little bit above NMRA specs. Would run all day at slow speed. Still cool at end of day.
