I know with my car and the sport cup 2's,
at zero or lower the tires can crack.
The compound does not do well in the cold,
so shipping cars with very expensive tires
they may have to replace was a no go.
The R's were not built in winter for this reason
I remember mine got build and problems with shipping
but finally got on train, I tracked the car and when it showed up
in Jan, first thing I checked was tires.
GM Had a big problem with its corvettes with cup 2 tires,
cost them millions to replace tires, Mistake was not made again.
I am sure moving and loading would not be much fun either.
for the record, my car never seen minus temps on train.
