We recieved a clarification to the questions that have been asked about cold-weather storage of the Ultra-High Performance tires that come equipped on the ZL1 from the factory.
Fbodfather mentioned this earlier today, but I wanted to stick it in a thread of its own, too.
Please note that this informational bulletin is from Goodyear, the manufacturer of the tires, and not General Motors directly.
**Also, I would highly recommend you read through the full bulletin and not take the picture alone at face-value.
