Regarding tires....
I have a question regarding the Cup 2 tires. I believe there are two issues with these tires that are bothering a lot of the owners. 1. They crack in cold temperatures. 2. Putting them on the wheels take hours and several tries and multiple trips to the dealers.
My question is, these same cup2 tires are used in a lot of other cars in similar sizes. GT3 is one example. I have never heard people say the same about the cracking or it taking 7 hours (one member mentioned this in the other thread) to mount 1 wheel. Something somewhere is not adding up. Either Corvette is using a different cup2 tire, or what else? Either chevy service don't have the right machinery or the training to put them on, or what else?
The GT3 wheels cost $4000 per wheel. I cannot imagine a Porsche dealership ruining those wheels and doing multiple attempts in 7 hours to mount a tire on them. There are GT3 owners who use stock wheels to mount PA4 winter tires on them and they do the mount/unmount several times a year.
What am I missing here?

NOT just the Cup tires.......but also the Super Sport tires. DO NOT DRIVE when temps are <20*F. The tires were not designed for low temps. They are summer tires.
If one needs to use the vette when temps are <20*F then get winter tires.

Someone said in the other thread that they have been mounting tires for 17 years and never had a tire that was as difficult to mount as this tire. That's kind of scary.

I believe the difference may be cars like the GT3 do not mount run-flats but both Z06/Z07 sets are run-flats. The double bead and the super stiff sidewall may be what is making the tire mounting so difficult. Also, many dealers/tire dealers may not have a Hunter 34 tire mounting device, which seems to be designed for these ultra stiff sidewalls and double bead applications.

The fact that they are runflats make a big difference in installation. Super wide and super stiff.....however, an experienced and knowledgable shop should have no problems installing them. My local Discount Tire had plenty of experience with my wheels and going through those big *** sizes. I'm in and out now...

I'm fine with all of that. My question was more towards why other cars using the same tire not having these issues. Specifically the mounting issue. Is it because the shape of the corvette wheels? Or the machinery chevy is using at their dealership? Or just skill of the person doing it?

If the correct machine is used then there should not be a problem......hope this helps.
