2007–2014 CTS spare. Be sure to read the description carefully. There are at least 3 different wheel sizes that look similar to this wheel (16", 17", & 18").

so just to confirm, with the 2007–2014 CTS spare, ony a 5mm spacer is needed on the rear and no spacer at all up front..?

Yup, CTS spare. Make sure it's a 18x4.

The 5mm spacer is needed on the front. The spacer isn't required for the back, although it is used in the pictures I posted.

Something like this is very tempting. Buy one thing and be done with it.

So you have a flat a rear tire and have one spare tire and one jack.
First you jack the rear and replace with the spare.
Second you jack a front and replace with the flat rear.
Third you rejack the rear and replace the spare with the front.
Forth you rejack the front and replace the flat rear tire with the spare.

Did it miss anything?

Yes, you may be able to jack the entire side up depending on the jack and the surface underneath.

I just wanted to bump this comment up from a while ago. I re-read this thread and this was hilarious.

The reality is that this type of blowout is incredibly rare these days. Modern steel radial tires are incredibly strong and unless you are wearing them down bald, you usually don't have to worry. I've gotten maybe 3-4 flats in 15 years, driving in some pretty crappy places, and in each of those cases it was something metal where the gummy interior tire sealed up around it pretty well. Didn't really have to add fix-a-flat, but did in a few cases. Most of these were able to be fixed with a simple plug, one on my old Gen 5 was on the sidewall and I had to replace both fronts. Runflats are a big scam, just a way to make you pay more money in the end. If the run-flat keeps it together, it's likely some fix-a-flat at the worst would have sealed it up and allowed you to get back just the same. If you actually drive on a runflat while it's flat, it ruins the tire, so you get to replace at least two runflat tires for treadwear (even more possibly on an AWD car, yay!). If it's a catastrophic blowout, well runflat isn't going to help you there.

I think spare-tire anxiety is real. Sure, if you do a lot of long XC drives in areas where you can't get any help, then maybe you should rig something together, but for most people, even those that go XC occasionally, it probably makes a lot more sense to just have the roadside assistance with your insurance.

Lastly, runflat tires are terrible. Which I switched them out on my BMW it was night and day. You don't want that crap on your performance car anyway.

Or you could...

Jack front replace front tire with spare
Jack back and replace rear with front.

Or do it your way.

Or get the modern spare tire and just jack and replace whichever tire has the problem. I guess there are a bunch of options.

Like mentioned above, if you use the jack position closer to the door, the whole side of the car comes off the ground, front & rear.

Ha haa. yes. You are parked in the breakdown lane (on the right) on a super busy highway and the flat is on the driver's side and its 104 degrees out and you have to pee. Otherwise, the a/c in the Camaro is awesome and will be waiting for you.

The factory puts on run flats and they are good for 50 miles so it seems that Chev and Oppenheimer are ok with not breaking the LSD. But I agree with you; the less miles the better on different sizes.
