Never thought cold temps could damage the tires. Learned two things now about tires and cold temperatures

I know right . Wow . Not sure why Michelin and GM are putting these kind of tires on street vehicles. Those tires that are cracking seem to be like a full blown race tire . Very peculiar tire for these cars when the weather can switch up so quickly in many parts of North America.

I was recently at a GM dealership and my friend who works there showed me how they had to maneuver other cars around in the garage to make space for the 2017 vets as they cannot store them in a cold environment.
Why put a product on a vehicle with such limited usage . I see Porsche cars all winter long with no tire issues and it's the #1 competitor for the vet is it not ...

I was chasing a Porsche that cold morning and had a hard time catching him in the corners. Porsche recommends tires for summer and winter driving for their cars.

Couldn't find any 17's that fit a ZR-1, but I did find that there are Nitto Motivo all season tires for the ZR-1. They are speed rated to 168MPH. Couldn't find a recommended review of them. But appears to be an option for running hard on cold surfaces and cold weather... Maybe[emoji848]

I think it's a waste of time searching for fat 17" Corvette tires that're going to be grippy in 20-40 degree weather. You just need to adjust your cornering speed to the grip available. And (I'm sure you probably already know), be sensitive and smooth with your inputs so you're not introducing abrupt weight transfer changes that will break the tires loose.

What air pressure did you run? I think our cars/tires want a little less than 30 lb. I remember that was a surprise to me. Most of my previous street car tires needed more pressure to keep them from rolling over onto the sidewalls.

When I ran my ZR-1 on a track with new, full tread Goodyears, I was impressed with their grip. But, that was not on a cold day. Probably in the low 60's that day.
