As i try to fit my spare tire (full size) in the trunk, it becomes apparent that the black 'tub' needs to be removed.

only thing is, i can't figure out for the life of me how to remove it!

someone help me out here. i don't want to break it...

OK looks like my dilemna is not over yet.

FIRST - i need a retaining clip thing for the spare tire (I plan on contacting Luke)

ALSO - i noticed this bar sitting underneat the tub. i don't want to just throw it away, and then later find out it serves a purpose, sooooo... what purpose does it serve? it didn't fit back in with the full size spare. is it just there to support the tub before a full size spare is put in?

its just for crash protection. the spare will take that job over for it. i still have my old tub in the attic

ahh ok. so i can safely remove it and store it with my tub?

How much money are you looking at for the entire spare tire upgrade?

I spent just under $90 way back three years ago, but that was from GMPartsDirect.

But, GMPartsDirect is a ripoff. I don't even want to go into it. :canttalk:

Get it from Luke for around a C-note. At least he knows what honesty and customer service is all about. GMPartsDirect can ... well ... bite the big one.

I've bought the parts I need to mount my spare tire and a wheel without a tire. I went to put it in yesterday and everything fit till I went to put the cover on.

I have see mixed reports of guys being able to get the cover on or not. My wheel is face down and no matter how I slide it around I can't get the cover to go down all the way. It is mainly lifted towards the rear of the car.

Are all of the covers the same? Mine is a 2005 and is made of a molded plastic with rings molded in that look like they are meant to line up against a spare tire.

Am I missing something? If necessary I can make a custom cover if I can find the right carpet to cover the board. If I have to make a cover, does anyone know how to get the right carpet for the trunk?

For those who have previously said they got their cover to fit. Did it really go down all the way?

In my 07 with my wheel facing down I am able to get the cover on and screw on the retaining circle. The edges of the cover do stick up a little bit (not totally flush with trunk floor).

I have an 05 and use the stock cover just pulled out the plastic thing. I had a BFG All-season tire on my spare and it fits nicely. With my BFG KDW, it sticks up a bit. So it really depends on the true tread width of the spare tire.

I have a 225/50-18 on an 18x8" Mille Miglia wheel and the cover still doesn't sit flush with the trunk floor. I would say it's 1/4 - 1/2" higher than the trunk floor. It's a little bit better than it was with that same tire mounted on a beat-up stock wheel, but only a little bit.

It is getting close to the time for new tires and I am ditching the runflats. I had a curbing incident when I first bought my vehicle 3 years ago and as such have a full size spare chrome wheel with a little curb rash that I will be using. I was trying to find Luke's info from a past purchase but I do not have it. I went to the Lindsay website and did not see him listed there anymore. I also used used the search feature and every post comes up as people mentioning him but that is it. I was hoping to get the part #'s for the kit or just oder it from Luke. Is the kit just the normal CTS spare tub that people swap in or do they just remove the tub all together so the full size spare will fit in? If that is the case then is it just a jack kit needed? Thanks

On a somewhat related note, I happened across this deal on Ebay the other day. $56 shipped for an 18x8" SRX wheel (http://cgi.ebay.com/ebaymotors/05-CADILLAC-SRX-Wheel-18x8-7-spoke-polished-opt-QF-/110610099694?pt=Motors_Car_Truck_Parts_Accessories&hash=item19c0e02dee). I haven't been able to figure out exactly what the offset is on those wheels, but from what I've gathered the SRX wheels are in the same ballpark as the V wheels, so I think it should be close enough to use as a spare. Then again, I don't know if the spokes would clear the V's calipers. Anyone ever tried one of the SRX wheels just to see if they would fit?

Assuming the wheel clears the Brembos this could be a great option for guys looking for cheap spares. Most of them on Ebay aren't listed with a price this low, but there's certainly no shortage of SRXs in junkyards, and it seems like most of them have/had the 18" wheels on them.

Offsets are 51mm vs 42mm for the V: http://www.ls1tech.com/forums/cadillac-cts-v-2004-2010/363226-do-srx-18-rims-fit-cts-v.html

Like you said, also unknown is the spoke clearance compared to the V wheels. They might be chunkier on the SRX since there would have been no need to maximize the clearance.

If a small spacer did the trick, it would probably make a great spare wheel.

I wonder if some trunks are different than others. I also have a Mille (did I get it from you???) with a 225 tire on it. With a couple layers of sound deadening under it, it still has some room before touching the cover.

Had a set of 18" Milles off an SRX. They were so cheap, I thought it was worth the risk. They do not fit over the Brembos.

Not sure what all is included in a spare tire "kit". Since most spares will be 5 lug the wheels will be useless, you can go to your local junk yard and probably get the jack and lug wrench for $20. No doubt the biggest expense here will be the spare tire if you dont already have one.

I was just asking the dealer to send me a picture of the 'build options' that my car has - I usually find this in the trunk or some place... well, she didn't find it, but she did find the label that talked about the tires.

There was no entry in the spare column - being this likely came with run flat tires, and now it doesn't have them... will this car have a spare??

Beyond that, where is this deal of install options located so I can research all the goodies I am getting on this copy?

There is no compact spare either, you'll need to get a full-size rim. I took the nasty runflats off my car, and now have a full-size spare, with the jack and wrench, and the mounting hardware installed. The cover installs most of the way, but pops up a bit. I found that to be pretty ugly, so I got a trunk mat to cover it up with.

I don't mind the runflats - I HATE changing tires! BTW, there seem to be a lot of options for these bad boys out there - which is the quietest/longest lasting?? I KNOW the day will come when I will have to change them ($1,200+ later)... but I want to be sure I am getting something that will last!

AAIIIC
01-26-11, 11:43 AM
Run flats are heavier, cost more (significantly more), and (in my experience on my CTS-V) have poorer ride quality due to the stiff internal structure. The difference in cost between non-run flats and run flats will more than pay for the jack and a (used) full-size spare. Not to mention there are way more tire options if you don't restrict yourself to just looking at run flats.

Unless you get lots and LOTS of flat tires, I just can't see any reason to put run flats on the car.

Search the forum, there are quite a few discussions of tires on here, it is pretty much impossible to just blindly suggest a tire for you as it depends greatly on what your intended use and expectations are for the tire.

"but I want to be sure I am getting something that will last!"
The first thing to realize is that if your main concern is how long a tire will last you will have to make compromises on performance. Most people don't make it to 20k on a Max Performance summer tire.

01-28-11, 12:23 AM
Depending on what kind of spare tire you have on your rim (thick rub strip, etc.), the cover may or may not sit flat over it. I'm guessing that metal bar I took out was for impact absorption in a crash.

What are you guys using for a jack? Did you just go somewhere like ebay and get one from a regular CTS, or are you using something else? Same question for the spare tire. Are you using an extra full-sized wheel/tire or is there a donut available?

trhs75
01-29-11, 09:51 PM
No 6-hole donut is available for the V. Regular CTS jack assembly will work, and the styrofoam case fits loosely in the back of the larger V rim. I got mine from one of those online discount GM parts places, but a salvage yard is a great idea, too. I bought a fifth regular rim on eBay. In retrospect, it would have been cheaper to keep one of my snow tires in the trunk as a spare.

I'm using a Mille Miglia V wheel with a 225/50-18 mounted. It barely fits. For the jack, I happened to have a jack kit from the 2nd gen CTS. I bought the kit to use the spare wheel and tire on a Corvette, and had the jack and such just sitting around (needed an adapter for the wrench, as the 2nd gen uses 22mm lug nuts). But if I didn't have that, I believe Lindsay Cadillac could hook you up with the jack and wrench.

"Styrofoam case"? What did you get your jack kit from? All the ones I've seen (from the 1st gen CTS) are just a shallow plastic bucket kinda thing with the scissor jack laid across it. The thing in the upper right:

FWIW, the CTS gen 2 kit I bought had the jack and such stored in the foam. It looked like it would fit perfectly at the bottom of the trunk well, though I honestly didn't try it. It would have raised the wheel up another inch or more, making it not useful for me.

trhs75
02-01-11, 12:55 AM
AAIIIC: My mistake. My V has a plastic tray/case thing from the regular CTS, not styrofoam. I have another car with styrofoam in there. The tray is designed for a 16" or 17" donut, I think, so the fit is a little loose. The jack stuff tightens into place securely, though.

03-13-12, 11:05 AM
Go back to the dealer and ask them to either put the oem run-flats on or a new rim and tire. Thats what I did and they got a rim and tire. It worked out good because last year I had a bent rim, and had it swiched out. Now the bent rim is a spare.

I would go back to the dealer and ask for a spare wheel/tire. That being said, I had the same situation when I bought my V and just found a wheel for sale on craigslist. You can get the jack kit from the normal CTS for about $60 from a junk yard, and with the spare face down you can still just barely fit the cover on.

Has anyone figured out what other makes compact spare will fit a CTS V six lug wheel. When I bought my car it didnt have run flats. I was given a CTS 5 lug compact spare tire and a jack kit and now the GM dealership is telling me GM doesnt make a compact spare for the CTS V. Some other cars spare must have the same lug patteren as the V ? Thanks

JimmyH
04-11-12, 10:19 PM
There is none. You don't want to use a compact spare on a car with limited slip anyway (at least on the rear).

The good news is that if you pull the plastic tub out of the tire well, a FULL SIZE wheel/tire will fit in there with the cover. You just have to put the face of the wheel down against the basin. Use a towel to keep it from getting scratched, or get an old wheel like I did and don't worry about it.

I bought a set of new wheels and tires for my V1 and have the stock set laying around. Not too big of a market out there for 6-lug car wheels. Also, the V doesnt come with any kind of spare.

Do any of you carry a spare with your V? and a Jack? and a lug wrench?

Considering keeping one of these stockers as a spare and selling the other 3 out to other people that had the same idea. But, I'm concerned with getting stuck with 1 or 2 wheels and being useless.

Has anyone else done this or bought just one? or would I have better luck selling the set. (which is a b word to ship)

The mounting pad and spokes wouldn't be affected at all, so I don't see how caliper clearance would change. They would just be taking an inch off the back of the wheel.

I'd be curious to see a measurement with a straight edge across the tire measured to the trunk floor. I'm using a 225/50 on an 18x8" wheel and it still is wider than the spare tire well is deep. I can get the cover almost flush with the trunk floor if I crank down on the big plastic center nut thing.

I used to have a stock wheel/tire in there and the spare tire well cover sat up probably 3/4" from the trunk floor.

hmm.. i guess i was thinking that making the wheel narrower would affect the offset that would then potentially affect clearance over the calipers

but now that you mention the width just coming off the back i guess that makes sense that it wouldn't change how it mounts over the calipers

The previous owner picked up an extra wheel for a spare and one of the jacks that comes with the regular CTS to set in the middle. The stock wheels that came with my car had a lot of curb rash and now on one especially the paint is starting to peel. I may be interested in buying one or two of your wheels if you end up splitting the set. As for shipping going parcel post through USPS actually isn't too bad. For packaging go to walmart and buy a couple of moving boxes that are about the size of the wheel when flattened. Just tape two flattened boxes to the face side of the wheel, and one to the back, then wrap the whole thing with plastic wrap and they'll be fine. I know because I've done it in the past, I can provide pictures if you'd like. Just don't slice the end of your finger off when cutting the plastic wrap like I did. :facepalm:

The trunk will be almost flush if you put the stock wheel in spokes down. More than good enough for me...

I have the full jack and spare setup. Love it for the just-in-case factor. Also I think the extra weight in the rear actually helps stabalize the tail.

Yes, the cover rides 1/2"ish up from flush but with a cargo cover no one knows or cares. And I carry stuff like heavy groceries in my trunk once a week.

About $60 shipped for the normal CTS jack kit. Loads of them on Ebay. Plus about 100 for the spare wheel/tire, but it has some rash on the front side and the tire is low on tread.

easy!

Has anyone been stranded without a spare in their V?

Yes, 2 summers ago, on a weekend (everything is closed on weekends where I was), about 14+hr drive from home. Had an incident the previous night and decided this holiday was over, im going home and having the car repaired. On my way out...maybe an hour down the road my tire pressure warning came on...I eas watching the tire pressure drop very quickly. Pulled into a gas station and got a can of fixaflat...used it up, rolled the tire and theb arremptd to fill with air. Nope. No good. Phone calls the dealerships assured the runflats would get me somewhere...decided to risk pushing forward in search of a tire shop rather than limp back where I started.
Long story short, found the only shop open in the area (canadian tire), found the rim to be bent and a 2" gash on the inside wall. The fact the runflat had made it as long as it did before losing air and then getting me where I needed made them worth it. But a full size spare in invaluable. I have not yet but will get one

While I was messing around in my trunk yesterday I came to realize that my car does not have a spare. Now that I know I don't have one I am virtually assured to get a flat in the near future. What are my options for a full size spare? I know that we have a weird bolt pattern/backspacing, so I'm wondering if there are any other options than buying a 5th wheel for hundreds of dollars.

ctsv247
12-23-13, 09:57 PM
Your only option is a full size spare which will fit in the well face down but it will not allow the cover to sit completely flush with the trunk floor. It will stick up but less than an inch and doesn't really cause issues. A cts jack assembly will the sit down inside the spare and makes for a nice fit all in all.

Watch the classifieds and you can find spare wheels.

Tire plug kit and a compressor. Unless you get a hole I. A sidewall you'll be able to fix it with that

I'd like to carry a full-size spare in my trunk (I'm losing the run-flats).

Problem: the wheel tub in my trunk is this segregated two-section thing. You can't put a wheel in it.

Will a non-V CTS tub work? Or are there other models of Cadillac/GM vehicles from which I can scavenge a tub?

Thanks in advance.

Your only option is a full size spare which will fit in the well face down but it will not allow the cover to sit completely flush with the trunk floor. It will stick up but less than an inch and doesn't really cause issues. A cts jack assembly will the sit down inside the spare and makes for a nice fit all in all.

What trunk well are you using? Or did your car not come with the well that's divided in two? My car's spare tub is molded into two sections.

There's a guy advertising a set of Mille Miglia wheels on LS1tech. Those are 18x8" (so 1/2" narrower than stock), which makes them fit slightly better in the spare tire well than the stock wheels. I have one of those with a cheap 225/50-18 on it for my full-size spare.

Plenty of discussions of this, dating back to the beginning of V1 existence. See above posts for a link to the FAQ for details.

So there's no replacement for the tub? The spare just drops into the hole left by the old tub?

Thanks.

Exactly. This is what we have been telling you in all 3 threads you asked yesterday.

I recently changed from run-flats to Pilots on my 2005. I went to the local boneyard & got the jack, ect. & 6-lug donut. When I rotated my tires, the spare wouldn't fit over the caliper. When I take it back, I need to know what will fit. Any of you guys gone this route?

I have a standard CTS-V wheel for a spare. If you watch the classifieds on here they come up for sale once in a while.

Do you have the oem tire size (profile)? Does it fit in the spare compartment? I have the oem size & it wouldn't fit flush.

Yes, it's a 245/45/18. I put the wheel with the outside face down in the wheel well, and it barely fits. The cover doesn't quite sit flush, but it's only up a 1/2" or so.

A 6-lug donut from what? :confused:

Merged your question in with a few other threads about putting a spare into the V.

The Chevy Uplander is 6 lug I think

As well as the SRX, but neither of them has the bigass brakes we do. I determined a few years ago that it takes a 3" spacer to get the SRX spare to fit.
