I once put some elastic bands in a fridge, and they became very stiff and hard to bend. One piece broke when it fell on the floor, which seemed very strange once the parts warmed up again.
Not all rubber will act the same, but tire rubber will not completely escape from this effect imho.
Also I think the stiffness increases exponentially with lower temps rather than linear. Otherwise the rubber band would not have broken like that.
I'd expect less than stunning performance from solar racers when temperatures are way below freezing anyway. Can't just blame the tires for that
