I've never seen tire companies recommend such a thing. If you guys have a link handy, please do share it.
A couple of links:

From Michelin: Mixing Tires | Using Different Tires | Michelin US

When replacing two new tires instead of four, be sure that your new tires are the same size and tire type as your current tires, and that your dealer always installs the new tires on the rear axle of your vehicle.
From Tire Rack: https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=52

When tires are replaced in pairs...the new tires should always be installed on the rear axle and the partially worn tires moved to the front.

That Michelin clip is pretty deceptive. In the preferred arrangement he was just driving and when it started to loose grip she told him to lift off the throttle a little. But in the second clip she tells him to drive hard then full braking, even when she told him to countersteer you could see the wheels locked and sliding. These are completely different approaches and they should have done both tests in both vehicles to be valid.

Also as a side note they must have disabled ABS.

Ultimately regardless of where you put them new, if you follow their recommendations they will be on the other axle sooner than they could wear to the same level. So if weather conditions such don't be an ass and overdrive your tires.

I don't think it could be applied to our discussion with the space saving spare, where you have half of the normal tire on one side of the axle for steering and breaking...
Anyway, let's see, if our space saver even clears the calipers on the front.I think it would.

For a normal driving conditions with front wheel drive vehicle would be really hard to lose traction to the rear( you have to really go for it).But if you have doughnut on the front and have an emergency situation where you are breaking hard to avoid an accident, your car would lose traction on one side at no time. Also, car most likely would pull to one side while you driving normally, with the doughnut on the front.

Can not say for sure..... but they say it just will not clear the front bigger brakes on GS Regals.

But, I'm not replacing two tires, Im putting compact spare. Am I reading it wrong?
My comments were about the general advice as to which axle the grippier tires should be on.

For using a spare, since it's very temporary and you should be driving extra carefully on it, it can just replace whichever one is flat, assuming it doesn't have any interference. As long as the car was built to accommodate a spare, you won't have to worry about drivetrain issues due to the size difference for a short period of time.
 

G-972456

The spare tire the oem part number is 84095141 for the 17X4 inch wheel. Tire rack sell the tire for around$60. A spare from a 2006Buick Lucerne or a Cadillac DTS 2006-2011 125/70/17 fits with room for a jack and tools.
The OEM jack part number is 23455285 $34.02 from Tasca parts (as of 9/16/18)
Just got an old Caddy DTS doughnut, $95 on E-Bay. Verified the lug pattern w/my dealer.
Thanks for your help!

Here are part numbers from an old post. If anyone is interested in a spare tire the oem part number is 84095141 for the 17X4 inch wheel. Tire rack sell the tire for around$60. A spare from a 2006Buick Lucerne or a Cadillac DTS 2006-2011 125/70/17 fits with room for a jack and tools.


GM Genuine Spare Parts (gmpartscenter.net) says part # 84095141 will not fit a 2019 TourX Essence. Is that true?

So new owner here (2 days old) and in the sale I negotiated that they provide me a spare ..like the above posts (even printed out one of the postings)

They are reluctant to order one as there are NONE per the factory for this vehicle. However they will reimburse me for any cost if I go ahead and order it.. Liability for ordering me parts not for my car. No big deal I can order them and they will reimburse

So guys what are the exact parts I should order and have them order.

Example - they can order the jack and tool kit, just want to make sure they order the one that will fit in the wheel well.

I plan on ordering this wheel: $93.00

Took screenshot below - GMPartsDirect says it does not fit 2019 TourX: Is this true? On the list of compatible vehicles, it shows 2018 TourX, but not 2019.

'Cheapest' would be to buy used parts and price will depend on your local salvage yard.

I picked up a 2006 DTS temporary spare and jack for $60 (TourX). I had an extendable lug wrench already.

My worry is that the tour x trunk is different than sportback with Bose?
Can you verify it’s the same? Thank you greatly

I do believe the Tourx has a smaller spare tire well than the Sportback. It may just be the difference between FWD and AWD. If you look at my pictures above from the FWD rental Sportback, it has a rounded spare tire well where the Tourx has a support beam running side to side at the front of the spare tire well that makes it shorter front to back.

Is this on a sportback or tour x?
Have you actually tried it on the front while driving?
Thanks greatly
This is a tourX. I'm believer that compact spare should only go to the rear. I know it fits the rear wheels. I'm afraid it is not going to clear the front caliper.

Can someone confirm that a 16” dts setup will also work or does it have to be the 17x4
Most of the spares I am seeing for sale are 125/70/16
