Attention ZL1 owners-to-be! Cold-Weather Bulletin on Eagle F1 G:2 tires - Page 10 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I think I'm going with the Contis and just leave them on all year. I'm not sure I'm up to swapping wheels and/or tires with the change of seasons. In KY we change seasons about 12 times per year.

Friends:

Hi - my first post!

I had a 2011 GT500 SVTPP w/ the F1 G:2 tires. Also added the Ford Racing Super Pak (750hp/719tq at the crank). Live in the St. Louis area, and have no garage. Let it sit when it was 35 or below, drove it v-e-r-y carefully from about 35-45 degrees. Traction is hard to come by, but driving is manageable if you behave yourself.

Seemingly no adverse impact on the tires.

But the days it since in cold or even possibly light snow, there isn't much you can do. So the best bet is to just avoid these tires?

I was considering getting these as I track the car in the spring/summer, but don't have the luxury of a garage. The car is driven in fair weather, but doesn't get "stored".

What do you experts say, stay away from the Supercar G2s?

They were designed specifically for the ZL1, and they're phenomenal!! If you have a choice...I would still choose these tires, unless you want to drive the car all year round. If you choose them, you'll have to take the good with the bad (as with all things) and learn when is appropriate to drive the car.

I regularly drove mine in temperatures between 32º - 45º during the end of the fall this year. A couple of the days were wet, too...but as long as you're smart, and conservative with the go-pedal until the tires are warmed up, they'll do absolutely fine!

But....once the temperature hits 20º or lower, I wouldn't drive it at all...and in any event, you'd need to wait for a full 24 hours of warmer temperatures before driving the car, or you might damage the rubber, per Goodyear.

I know there's a lot of hesitation with these tires, and even more sour grapes before the car was out because of the Previous generation Supercar tires' reputation on the Corvette. But I'm a huge proponent of the tires after living with them for 8000 miles, especially for ZL1s. They're awesome!!

The problem with that plan is you never know when things will go sideways and you need traction to avoid situations or make an abrupt stop. I do not see the logic in driving these cars like you are on eggshells. You are better off parking it in cold temps.

I do think I'm going to have to pull the trigger on these.

Oh, I agree completely. That's why the car is safely parked for the season. :( Makes me sad not to be able to drive it...but there it is...as configured, I can't!

I didn't have to drive it on eggshells...just leave an extra car-length and it never skidded or shimmied on braking, even in stop-and-go...not once. There is no black-and-white: yes you can drive "now", but not "now"...and there comes a time in the gray area that the car can no longer be driven safely in the cold weather, with these tires. Until you get to that point...it's fine, and you just need to be a little more aware of what you're doing. That's all I was trying to say.

You would have been okay if you're smart, which I'm sure you are.

The Conti ExtremeContact DWS tires that are closest to the factory sizes are 275/35/20 and 315/35/20. See the attachment. these are both within the +/-0.5in that Tony recommends.

Will these sizes affect the speedo accuracy? If so, how much? Thanks,

I don't know for sure but I wouldn't think so. They are only off by 0.3 out of 28in. I guess you could calculate the difference.

Aren't the factory sizes 285 and 305? They show available. Why wouldn't you stay with those? Please correct me if I'm wrong. I need to order these and don't want to get the wrong size. I'd like my speedo to be accurate also. Thanks.

Those sizes are not available in the ExtremeDWS. The only sizes that are appropriate are listed in the PDF file. See the thread below.
