	I read in an article somewhere that heat buildup in the tire
sidewalls can be a significant problem for airliners, I suppose because
they want the landing gear to be as small and light as possible for
a given load. According to the article, if a plane at near maximum
weight had to taxi for a long distance on a hot day, they might have
to wait for the tires to cool before takeoff in case they had to
abort the takeoff and brake to a stop on the remaining runway: otherwise
the heat from the brakes added to already hot tires could cause the
tires to fail.
	Is this correct? If so, do they ever spray water on the
tires during runup to cool the tires faster?
