: Aftermarket spares for the ATS?

Hi everybody, new guy here,

I was at the Chicago auto show talking to a few Cadillac execs and was told the ATS would not be coming with a spare tire, instead having standard Michelin Primacy MXM4 run-flats. That sounds nice for keeping weight down, but I would still want a spare tire for worst case scenario (Not to mention there is no way in hell I'd buy run-flats after the original tires were out of tread).

Obviously it's too early to see how much it would cost to have one put in. There is barely enough space to fit one under the trunk floor, there is a space for a compressor, tire goop (which I would throw out) and some empty space. I'm just wondering if anyone here besides me would purchase an aftermarket spare for the car.


So, would you?

If there's a spot for a donut, that's the way I'd go ... maybe. I'm not carrying a spare now, only two cans of spare tire, so not sure what I'd do in an ATS-V.

If there is a place to store it unobtrusively, I'd buy a mini-spare (or hopefully, the one I've got in my '08 CTS-4 would be able to be transferred), since I view it like "insurance" of sorts. I prefer to save gas other ways than by eliminating the spare tire.

Was it all ATS's or just certain models/optioned versions? If you get the one with the supposedly larger brembo front brakes, it may simply be a packaging issue of having room for a spare large enough to clear the brake calipers.

Is it known if the trunk will even have a well for the spare? From the underside pictures it is hard to tell. Possibly they elected not to even have room for one as it is going to be a rather small car and they may have tried to maximize the trunk space.

The skeptic in me figures it's a way for GM to convince you to maintain your Onstar membership ;)

Run-flats are a ripoff. They cost 2-3 times high-quality conventional tires and you can't mount regular tires on run-flat rims. They also require special tools and know-how.

What? There are no special "run-flat rims"...

I replaced the run-flats on my V with regular tires. No problem.

Run-flats are a joke though. I didn't realize that is what they are going with. I will NOT buy another car with run-flats. Hopefully they will be an option, not standard.

As for the lack of a spare, get used to it. If you get a base ATS without Brembos and without limited slip, that is the only way you will be able to use a compact spare. They won't clear the Brembos up front, and it is ill-advised to use a smaller diameter tire on a limited slip rear axle. Drive more than a few miles and you will start burning up the clutches.

I have gotten used to life without a spare. As long as I don't have a blowout (which has yet to ever happen to me in 20 years of driving) the inflator will get me home. And on road trips, I throw one of the tires from my other set in the trunk.

I have been running run-flats on my 2001 Corvette and never had a problem. The spare just adds weight and cost but if you do replace with the non run-flats then I would carry an inflator kit.

To the people that dislike run -flat tires, I'm sure that since the first edition they have improved. In fact, I believe the era of the spare tire, has all but ended.

I have enough peace-of-mind with conventional rubber, a can of fix-a-flat, and AAA. A spare is great, and I'm not sure why the manufacturer's have gotten away from running a spare, but run-flat tires are too much of a compromise in the categories of performance, comfort, and value.

The ATS already has the smallest back seat and the smallest trunk in its class, so I'm guessing it's as much about saving space as weight. In my last two cars I replaced the run flats as quickly as ai could and run without a spare, just fix a flat goop. So far, so good, but I appreciate I'm rolling the dice with blow out risk.

I blow out a tire about once a year on average. No spare or option for aftermarket spare=no sale. A spare turns a 2-hour wait for AAA in the middle of nowhere to a ten minutes' episode of inconvenience.

You should check your tire pressure more often. It's the main cause of blowouts! I check my tires every three months and even within that amount of time you will lose some tire pressure. Better to be safe than to be sorry! Especially if you will be having your family in the car! You can buy one of those small round tire pressure gauges from WALMART or auto parts store.

Yep, nails have nothing to do with it...

Nails have a lot to do with it. Depending on the severity, you can carry a can of green slime to limp to a shop.

Nails are no match for routine maintenance, TBJS. Jeez...

I go through a tire a year as well, generally in the late spring early summer. Sometimes you just cant ignore construction areas.

I check my tires every fuel stop (once a week). I lose tires because of poor road maintenance in C-town. You must live someplace where the roads are perfect.

Sooo, does anyone know of an aftermarket spare for the ATS? I'm assuming 17" since it needs to be able to clear the front brakes and a 45 sidewall. Does anyone know if there is a special size number or something like that to make sure the bolt pattern matches up?

I don't know why, over 3 years later, Googling "Cadillac ATS compatible spare tire" only gets you articles about the ATS not having a spare instead of actual answers to the question.

There is no spare out there unless you drive a base model. Asked and answered by a poster. Also, a blowout is a blowout; run flats won't do you any good. Plenty of of fix a flat options out there......I would NEVER have run flats again; horrible ride and handling.

Actually, even the base model doesn't have a spare. Instead of run-flats, it comes with a can of fix-a-flat and an air compressor.

I haven't had a flat in years. For $39 you can get a kit and your good to.. This my plan B. Plan A is my RV roadside assistance called Coach Net. Covers my RV and all my cars. Used a few times and it is top notch service. Note - cars are covered even when not attached to the RV.
