Space Saver Spare Tire Size TourX Essence

[KingDapostrophe]

Just wanted to share my spare setup. Going on a long road trip tomorrow (through Colorado, I should be able to test out this AWD and get some great pics along the way).

Picked up a spare from a 06 Cadillac DTS from a junkyard about 30 minutes away. When I test fit it, I immediately noticed that it doesn't sit evenly on the base of the well (duh), so I had to get creative. I cut the bottom part of the stock foam storage thing with a multi-tool and a bread knife around the same level of the flat part that the sub sits in.

The bottom of this piece is contoured to level out the bottom of the spare tire well, so when cut, it's a nice flat surface for the spare to sit on. I then wrapped the spare in a fabric bag that came with my table saw. It's been sitting in my basement for a year, so it's about time I found a use for it. I picked up a jack from Lowe's, and already have a breaker bar and socket set in my tool kit (which is strapped in the hatch where the first aid and triangles are supposed to go. As you can see in the pic, the sealant fits pretty nicely in there. Not pictured is the portable pump, jumper cables, jack, and a few other small tools that I wrapped in old socks and tossed in there. I'm pretty happy with this setup, and if it turns out that I get unlucky and end up with the water in the spare tire well issue, the wheel and everything else is still well elevated by the foam.

The only hurdle I had to jump was getting the plastic piece to screw back in. The sub on top of the spare was just a little bit too high, but the flat part of the plastic piece pops right off and that provided enough relief to get everything screwed down. I'm pretty happy with out this turned out.

Can anyone tell me what the stud pattern is for the GS, please? So far as I know the GS and the Commodore VXR are basically the same spec particularly around the 20" rims and the Brembo brakes on the front axles.

I thought all the Opel based Commodores had the same stud pattern with a PCD of 115 mm. However I have been told the VXR has a PCD of 120, with data from one after market rim dealer confirming 120. Yet all the data I can find otherwise says the PCD is 115.

I'm pretty sure the GS and VXR will be the same. Any information will be appreciated. Thanks.

The GS was never optioned with the same 20" wheels that are on the Insignia/Commodore VXR. Only the Insignia/Commodore VXR have a 5x120 lug pattern. The GS lug pattern is 5x115 and has 19" wheels.

Thanks for that info. For some reason I though the GS has the 20' rims. The style is exactly the same for both the GS and the VXR. Perhaps that's why I though they we both 20".

There is plenty of confusion out there as several wheel sites quote the 5 X 115 for the VXR

Here you go mate, now Im curious the accessories you get ie air compressor etc..

I swear the Holden part numbers for the foam were posted but I can't find them in the search. Do you have the part numbers for the foam pieces particularly the piece on the left hand side that holds the jack and wrench?

 

[ZB Commodore Owner]

I've followed all the threads in fitting a space saver spare and don't recall the Holden part number being quoted anywhere. I made my own foam pieces.

I'm back on this project, as I've been told the used spare wheel I have with a 5x115mm bolt pattern does not fit. I pulled a rear-wheel yesterday and tested the spare-wheel fitment. No go, seems like the lug bolts on the spare wheel measure to 115 mm, but the lug bolts on the vehicle measure to a bit less (110mm?). Is that even possible that our 2019 TourX could have a wheel bolt pattern less than (5x)115mm? Certainly, my measurements could have been inaccurate to nearest mm, but the spare (used) wheel would not fit on the vehicle. Planning on taking more "back-road" trips and would like to have a spare.

The spare you have is smaller than the OE tire, correct?

I have a spare that fits in the spare well (tight fit) but the circumstance is smaller than the OE wheel.

Yes, the spare tire is a 125/70/17, the spare wheel is a 17x4. I don't know why the wheel won't line up with the lug bolts (studs). Or is the used spare wheel, the wrong one or damaged? Or maybe I can't measure accurately enough? It's always something

I too, would like to finish getting a spare for my Sportback. Last week I had my second sidewall blowout since buying the car and I had to get a friend to bring me a jack and a 19mm lug wrench, and then I took the wheel to a local Mavis Tire and had them put a $170 "temporary" tire on it. I say temporary because they didn't have any of the tires I normally buy in stock and I'm pretty close to replacing two of them. Unfortunately, the tire that blew out was one of the tires I wasn't planning on replacing, so now it looks like I'll be buying four tires instead of two.

I read this thread a couple of years ago before I bought my spare and I was sure I got one that fit, but when I had my first blowout I realized it wouldn't fit around the brake caliper. I bought it at a junkyard, so I wasn't out much money, but I never went back to find one that fit. So here I am again.

I need to definitively confirm what spares will work on my car and I can go get one next weekend. I have a Sportback Essence FWD. I really liked that first spare because it was a five-star and one of the better looking spares I've seen. Anyway... just wanted to provide an update about my quest for a spare.

My question for the group is:


Is it possible to fit a spare wheel in spare tire area / trunk / cargo area that sit he same height as the OE wheel?

When I compared the size of the OE tire and the spare, the side difference is significant.

Thanks abizzle for your reply,

Interesting, similar to my situation. I had a sidewall blow-out on the OEM Conti's when we first got this vehicle new in 2019. Almost all the way to work early a.m. on rural backroads, I pulled-over at nearest gas station large lot as I could see the tire air-pressure dropping fairly quickly in the right-rear tire.. I thought, cool, I know which tire to look at (thanks new-to-me TPMS). So I got out the little compressor and goop, and went through that new-to-me process. As the goop was spraying right at me (uh-oh, sidewall blowout now apparent). I was able to get it to hold about 10 PSI and quickly threw the little compressor and almost-spent goop bottle in the vehicle and get to work while seeing that pressure drop to single-digits (happy it was holding a little, not happy there was no spare. I ended-up getting 4 new tires installed, etc, as I was scheduled for a 500-mile trip in this vehicle the next day. It was at the tire shop I learned the spare wheel I had would not fit. I have since confirmed that, and want to remedy that situation with a spare wheel and tire that will fit in the well with the subwoofer. Thanks to the good people on this Forum, that seems doable, and I'm so close.

94cruiser,
I don't think so.

I just briefly looked at the site and it seems like there might be enough info to determine the correct wheel and tire size, and the correct hole spacing. The five-star wheel they show looks very similar to what I bought, minus the extra stud holes. I like the fact that they offer an entire kit however, I’m currently “ballin’ on a budget” so I’m gonna have to go the junkyard route. I have a 4-way lug wrench and I can pick up a scissor jack at the junkyard as well.

This is a long thread and the info I need is probably in here too. I wanna say someone figured out which donor vehicles had a compatible foam insert for holding the jack.

You’re welcome!

94cruiser,
I don't think so.

I removed my Bose subwoofer and added two 10’s in a hatchback-style box, so I have a bit more flexibility. I have enough room for my box and an amp rack, while maintaining the ability to open and close the cover over the spare well. I’m pretty sure someone in this thread ended up with a solution that would hold the Bose subwoofer by storing the spare face down. I think they ended up with the cover being flush also.

I just haven’t made time to read the thread again.

The wheel and tire are available without the other stuff.
The tire is rated for 80 mph and way more miles than a donut.
But WOW has the cost gone up from when I got mine! 😱

I'm considering getting the wheel and tire from this vendor (have a jack and wrenches that'll work for this), but I think it won't fit in the well. I like the idea if having that new wheel and tire (after trying all of this again, I'm getting the feeling the used wheel may be damaged or the wrong one). They do fit in the well though.

All this for something I hope to never need again...
