Ok, I only plan to drive the car during the summer time to begin with. I do not plan on changing the stock tires. According the the interview with Derek Joyce:
GF: How will these cars are gonna handle in winter driving?
DJ: You’re gonna need a different set of tires for the Track model. It’s a summer compound. It’s not gonna do well in the snow, we call it a Track
model for that purpose, its for the track and street, but its not made for snow belt driving in winter. So ya you might need to get an extra set of winter
tires.
GF: Stability control? Will that for those that do have…
DJ: Ya you will be able to maintain control with SC, obviously that gonna help. Obviously with traction control that’s gonna help a lot. With careful
driving but as a manufacture we don’t recommend that with summer compound tires. Even with ABS if you brake hard with snow or ice it takes a
long time to stop. It’ll depend on how you drive but we as a manufacture don’t recommend using the Track model in the snow.
