I must disagree here. One of the components of concrete is sand.
So it acts much like sand papper, grainny. It rips and shredds at
the rubber, where as on a hot sunny day the asphalt,
(which is made up of tar and rock) heats up and expands, there by melting
the rubber as it causes friction. On a cold day the friction alone will
be enough to heat the rubber, thus leaving a skidd mark.
