C7 tire wear
Suppose I bought a new C7 and drove it 20% around town, and 80% highway. Generally speaking, how many miles could I expect to get out of a set of tires? I know it varies with how aggressively the car is driven, so please assume average in that respect. Thanks!

You definitely jumped to an incorrect conclusion, so I'll add a few more details.
In 2004, I bought a new Mustang Cobra that would dissolve a set of tires (front and rear) in 16,000 miles under normal/conservative driving conditions. There wasn't anything wrong with the alignment, nor was there anything related to the differential. The tires were just built from a very soft compound, and they went away in a hurry. At the time, there was no durable alternative, which added up to a pretty sucky/expensive situation that I don't intend to get into again.
I'm fine with 30,000 miles or even 25,000, but I'm not buying another car that lands me in the tire shop to drop $1100 every 16k. Anyone who drives 30k a year like I do, probably shouldn't buy a C7 if the tires have to be replaced every 16k, hence the question. If they last 25-30k, I could live with that. If they are gone in 16k, I'll pass on a C7.

The OEM Goodyears on the C6 typically lasted only 14,000-16,000 miles and many replaced them with a different brand.
The C7's come with Michelin, which from what I've heard/seen last much longer. I've not read any complaints about Michelin's wearing out quickly. If I get ~25,000 miles I will be happy because that is 4 years for the way I drive the car.

My 14' had about 5-7 / 32nds left with 12k miles on them.
My 15' has a little under 12k miles and has 7 /32nds on them and that's with my 15' being supercharged for the past 8k miles!
All depends on how you drive the car.

I got around 30,000 mi out of a set of Michelin Pilot Super Sports on my EB Flex. Don't see why the fronts won't go that far on my Vette. The rears will depend on burnouts!!!!!
On my G8 GT, the fronts were fine at 25K but the 285-35-19 rears (Bridgestone 050A's) only lasted a little over 12K.... They had less rubber from the factory, but didn't like my style!!!!
So if you drive like a grandpa... you might actually get 35-40K... and have NO FUN...

Interestingly, just today when I took my new Stingray in for an alignment, the mechanic noted unusual tire wear (outer edges wearing) on the rears. That, with only 700 miles on the car.
Of course, he found the factory rear camber adjustments way out of specs at +.7 and +.8 degrees. I have been pushing the car around corners even during my break-in period, just not applying high RPMs or full throttle.
The funny thing is that the first thing I did when I got my new car home, was to check my alignment. I got the front values fine, -0.4 & -07 but, I reversed the numbers on the back in my trig calculations and instead of + values I came up with - values. Goes to show you that at times you get what you expect (negative camber) and not what you actually have :-) (positive camber).
Now, I'd like to find out who and why at GM's set such positive cambers in the rear. According to the printed specs they were way out of range.
I was impressed with the handling before but now, after placing a nice set of negative cambers on the car it corners as if on rails. Might even be a tad too neutral for safe public road driving. I did install the Z51 rear sway bar only and now I will likely put on the Z51 front bar as well in order to give it a touch more understeer.

C7 OEM's Have a wear rating of 300 -320 ( I think )
I had a C6 that wore out ( conservative driving ) at about 14K miles.
I put Conti DW non run flats at about $800 per set with a 300 wear rating. I carry a small air pump and a plug kit.

Not trying to nitpick but Tire Rack uses 6 yrs or maybe 7 at a max if stored inside before you need to pitch tires due to age. Don
