There must be some CYA to this because undoubtedly there are some people out there that would use them as a parking brake on sloping ground. Tires must shrink somewhat in diameter, but how much? Is there testing that shows by how much or tech. analysis to predict by how much? Maybe cranking them up tightly deforms the tire enough to overcome shrinkage? But there'd be no way of specifying how much to tighten them. Stating regular wheel chocks are required definitely absolves the manufacturer of liability.
