Ordering a C7 - advice?
I am looking at trading in my C6 with about 85k miles for a '19 C7. I am going to do a factory order and will be going with a coupe and just thought I would ask for any advice folks have.
I am worried about the tires which crack below freezing temps from what I understand. Also, have they changed the sizes on the wheels at some point to 19/20 inch as standard?
I am going with the manual transmission this time, my C6 has the A6 auto.

Sounds like in Canada you probably have to buy form a local dealer.
RE tire cracking. That can occur at perhaps -10/15 C but not at 0 C! Lots of "legal" warnings and recall the first cracking pic was from Canada in 2013. Funny, that pic of cracks, only in the tire tread, was the only one that was repeated on the forum for over a year! But that car was reportedly transported by train over the mountains with temps of -40 C/F! That said, if you plan on driving often when it's 4 C or less best get all-season tires for traction reasons- NOT cracking.
In Eastern SC I seldom have to drive when it's that cold but last year had to drive when it was -4.5 C. Yep traction is less, but tried an aggressive stop as a test- it was OK. And no cracks!

Seriously, if you live in Canada, and plan on driving the car in winter, buy all season tires or performance snow tires. You'd be a fool not to.
And yes, it looks like they did make 19/20 standard. But check with a dealer to be sure.

The OEM tires are prone to cracking if driven in temps below about -7C, but even if they weren't, they simply don't provide the proper grip below that temperature so if you're going to drive it occasionally in the winter like you've done with your C6 you will definitely need to swap them out for all season tires. And as others have said they now come standard with the 19/20" Z51 style wheels. That started in 2018. I'm looking forward to seeing you on some cruises this year in your new car when you get it!

Thanks all for coming through, appreciate all the replies, this Forum is great! Now I am clear on the wheel size and I also just wanted to be sure of anything I should know but it seems like it is looking good!

When I bought my 2014 Z-51 and ordered the options I bought the 2nd package and cherry picked some options that were in the highest option package because that had some options I didn't want on the car !!!! Wayne

You will never be disappointed by ordering as closely as possible to your "perfect" car, even if you must splurge a bit to do so. However, you may well regret it later and wish you had, if you don't! GO for it!!!

Patman, I definitely would get all-season if I drive it regularly, I was just worried that the summers that come with the car will self-implode as soon as the temp reaches freezing

Nice! What interior color are you going with?
