I realize some of these models have already been listed, but there are a couple more that I don’t think anyone has mentioned. The website for one of the local U-Pull-It yards gave me this list when I did an Interchange search.

Scored one of the 17” premium 5-spoke spares today for $16.05. It is part number 9594807 and it has a brand new 125/70R17 tire on it. It came from a 2008 Buick Lucerne. Now all I need is a jack and I’m all set.

 

[visitor]

#04766498AA Chrysler jack with 19mm hex drive head fits & works well.
Our local yards don't sell jacks & usually pull them from the cars, but i found one ($5.99) w/handle ($1.99).
Also got a "FUMAGALLI F2133 04 11 22 T DOT made in brazil DHB 17X4T" rim (only slightly rusted) with Continental 125/70-17 ($5.99)

I tried a 16" compact spare which fit on the rear hub & caliper, but the speaker wouldn't quite sit down in the rim as well as in the 17". The speaker will sit on top of the 16" rim and you can close the compartment, but the rim diameter is just barely too small for the speaker to sit down inside, so it rides up on the edge and tends to shift part way down cocked in a non-flush position.

Also, a 145/70-17 does fit with speaker, jack, etc. It's a nice tight fit - actually had to remove the rear plastic trim to get it in there (or force the tire by, bending the plastic). I have to remount that one though, it came on a non 5x115 rim.

Thanks for all the input here!

It gets better 😛
Today i scored a full jack set

and 145/70-17 Goodyear temp spare from an '09 Cad STS on a #9598061 7-spoke rim..

= $22.31 including tax + envir fee
Fits well over the front caliper

and about as close to the original tire as you can get from a compact spare, but of course it doesn't fit in the spare storage well 😢
Turns out, that Goodyear 145/70-17 is a full inch taller than the Maxxis 145/70-17 spare i had gotten RE my previous post.
So, i remounted the Maxxis tire on the #9598061 7-spoke rim.
It fits perfectly in the well if you remove the rear plastic trim first,
then you need to remove the extra plastic washer (circled blue in next pic, it just pops off the two little tabs) to get the hold-down nut to catch the threads on the bolt,
put your plastic trim piece back on & there's room to close the compartment flush with jack, handle, compressor & sealant bottle placed around the sides of the spare.
For me this is the perfect scenario.
All your input here helped guide my to what to look for and a very lucky find at a local yard made my day!
👍

Well done.

I'm keen to do something similar. We don't have the range of second hand rim choices here. The only GM brand sold here was Holden. I'll have to go looking to see what models had space saver spare and then find one that fits the stud pattern etc. Otherwise the other option is getting a new one from the dealer at new price.

 

[abizzle]

I’m glad somebody is making some progress. I haven’t had a chance to look for a jack since I got the spare tire. I also wanted to sand and paint the wheel I got at the junkyard. The weather has finally cooled off enough to work on the car in the evenings, but as soon as the sun goes down here come the damn mosquitos.

The next house I buy or build will have a climate controlled shop with a two-post car lift.

I have ordered the 17 x 4 spare rim & tire twice from LKQ Online. 1st time they sent a bare 20" full size rim only (at least the bolt pattern was right). I called and asked them to check carefully before they reship.
2nd time they sent the 16" spare which will not allow the subwoofer to fit 🙁

I'll try again Monday or get my money back !

Although I have only had two flat tires in my driving lifetime, I am uncomfortable with having no spare tire for the first time due to the upgraded Sights and Sounds package. Armed with the information from this forum (thank you!), I got the compact spare wheel 84095141 from the parts department at the local Buick dealership ($43 after $105 GM Rewards credit) and a Falken FK-090 tire from Tire Rack ($77). GMpartsdirect had the wheel for $95 but I did not know what their shipping charge might be, and anyways I wanted to use up the GM Rewards points on something useful from the local Buick dealership, which was not an option from GMpartsdirect, apparently. The local NTB store kindly mounted the tire for me without charge (nice manager!), and I installed the spare in the tire well after removing the foam insert around the Bose subwoofer. I padded the metal bar in the trunk well beneath the wheel with cloth to prevent scratching, and added an AirPak between the tire and the well to prevent any possible movement. Although I have the tools (battery-powered jack, deep well socket, rachet, breaker bar) to change a tire, for the first time I am going to leave it up to GM Roadside Assistance or my AAA Plus membership to do the heavy lifting part if I should ever need it. It is worth it to me to get the known correct new parts instead of having to search out used parts. But it must be a cost and weight cutting move by GM not to supply the compact spare with the upgraded sound system, since they could have done it simply by leaving out the foam insert piece that surrounds the subwoofer.

How tight is the fit of the tyre/wheel between the front and rear sides of the well? I've just bought a space saver (genuine GM) and the fit is very snug/tight against the plastic lining below the rear lip. There is no clearance at all, you have to ease it past the lining and when taking the wheel out you need to press the lining back out of the way.

I notice your wheel well has fluted sides whereas mine doesn't.

What size is your tyre? Mine is a 125/70R17

I wonder if it is the pressure I have in the tyre, 60 psi which is recommended.

Looks like:

galdrago has a Falken FK-090 T125/70D17 98M -> overall diam. 24.2"

ZB Commodore Owner's Continental sContact T125/70R17 98M -> overall diam. 23.9"

The well of your '19 Holden ZB Commodore RSV Liftback looks, from the picks, similar to our TourX, while his '20 Regal Sportback well looks, as you say, fluted. If that Sportback well is the same size as ours, there would be no room for any AirPack at all with a 25" diameter tire.

our Maxxis TP10355500 T145/70R17 106M -> overall diam. 25" (inflated to 60m psi) is the largest we could fit , as it squeezed in snug as can be, with the rear plastic trim piece removed & then replaced after the tire is down in the well.

I though I was going to have to take the plastic trim off to get the wheel out. Fortunately I didn't. I had the trim out the other day when I was removing the foam liner that the sub woofer fits into. It wasn't easy to get all the clips located when fitting it back in.

I know you don't take the wheel out very often but it would be real inconvenient to have the remove and replace that trim with the risk of damaging or breaking the locating clips. With the wheel mounted the way it is you have to take it out to access the valve to check its' inflation.

I don't think there is any way I could fit a 25" wheel.

What do you have supporting the wheel to stop it rubbing metal to metal with the bottom of the well?

If you can see under the wheel, towards the front, there's a thin foam pad that i pulled from some GM vehicle. It was a circle with a section going straight across the diameter (like the Greek letter Phi), which i split in half. It fits under the front half of that wheel in the well and balances the fit so that the wheel sits flat and doesn't wobble. The fits is so tight on the outside of the tire, though, that i don't think it would move in there anyways.

Thank you.

Mine was a very snug fit. It wasn't going to move, at least not easily. It sat on quite an angle with the front much lower than the back. This meant the centre spigot/rod which the lock down nut fits onto wasn't in the middle of the rim centre. I wanted to level it up somewhat and have a cushion between the metal of the rim and the metal of the wheel well floor. Hence the question on what you did. I have a couple of ideas to try out.

Since the distance across the diagonal of an object is further than the true width, I'm hoping that by squaring or levelling the wheel up it won't be quite so snug.

From the various pictures posted in this thread from different vehicles, I can see that the trunk wheel wells on the different models (Holden, Buick Sportback, Buick TourX) are indeed different. That's why there was clearance on all sides in my Sportback trunk well with the Falken FK-090 T125/70/17 inflated to 55 psi.

I think it's more important to note the differences in body style and drivetrain than brand/model (wagon AWD vs. sportback FWD/AWD). My GS shares the same limited space in the spare wheel well as @ZB Commodore Owner's RSV. I tried fitting the foam pad @visitor mentions under my spare with no luck. It's simply too tight.

When I get a chance ZB, I will take some pictures to document what I've done to make it work in our style of wheel well.

Here's my spare tire setup for the GS (thanks to all the trailblazers in this forum and this thread specifically):


The spare is a T125/70R17. Absolutely nothing larger will fit without modification to the spare wheel well. To prevent the tire from rubbing/squeaking against the spare wheel well, I purchased a spare tire cover (meant for the spares on the back of an SUV or RV). Here's the link for the one I purchased: MOONET PVC Leather Spare Tire Wheel Cover - 13 Inch for Tire Diameter 22"-24"

The subwoofer fits just fine and is easily removed/replaced:


The cover also serves to eliminate the metal to metal contact between the wheel and spare wheel crossmember. It's also a lot slicker than the rubber so when removing and installing, it slides on the paint instead of gripping. I cut a hole in the cover to allow it to fit over the bolt:


I planned to use the foam ring from an older Cadillac under the spare but it was too thick and the spare could not be installed (with or without the cover on the tire). I even tried cutting it in half to only sit forward of the crossmember but that didn't work either. Instead, I just folded up a thick microfiber towel to provide more noise suppression and cushion between the wheel and crossmember.The inflator and goop are under the foam on the left. The jack and other tools are under the foam on the right (wrapped in a t-shirt). The microfiber and t-shirts are a temporary fix until I can come up with something a little more polished:


There is still a little bit of a rocking motion, but I think it is essential to easily removing the tire without screwing up the black plastic. The amount of free play and removal can be seen here. The tilting motion to remove the tire seems to work the best despite the rocking, it is greatly reduced once the sub and wing nut are reinstalled. I have heard no sounds from the spare since installing 5k miles ago:
