OK, I have been searching, and answers are all over map.
Some say 04 and up GTO Mini, one says an Equinox spare, another says a Cadillac spare or C4 spare. One says a GTO mini will break your studs. (Thought only a real wild lady could break one of those!)
Just want it for local use as a spare stored in garage with small jack
and brought to me, likely by my GF in case my inflator can, plug kit, and mini-12V compressor fail me. They are all on board along with a mini jack and lug wrench.

Most of my trips are local and I have USAA road service, but like to keep towing monkeys as far from the Vette as possible. Would rather limp slowly to my tire shop or home.

So are there any expert last word, definitive, go to fitment alternatives for a small spare out there?

Thanks Guys,
Dave

The problem with a 'spare' for the C5 is the offset front/rear sizing. In this case, I'd just get one each of a front and rear wheel in the same size as your current rims. The C5 rims are large, but not so big they can't fit in a trunk or an SUV cargo area, and my 125lb wife can lift them.

Most use a plug kit and some fix a flat, this will get ya home or to a station for repairs..
Reason is; on the REAR,,if the tire is to small / big it could do damage to the rear-end clutch pack (I think) and the TC will most likely kick on and not like it..and I 'm not sure about 04" but my 01" has 17" front and 18" rear, so you would need 2 spares.... Lots of good info out there. Myself, I don't want to risk any damage...Had a brand new (L) rear cut by a hunk of metal, you could put 4 fingers in it and it was less then a week old,, and I was local so a bub came out with one off his vette and we got it home..UPS come couple days later..

Not a bad idea if you just plan to have someone bring a spare to you on those rare occasions you might need one.

The other thing to consider with a small spare tire is whether or not the wheel will clear the brake caliper, especially up front as the front calipers are larger than the rear calipers.

Also the small wheel will have to have a sufficient center hub diameter to slide over the hub of the bearing assembly.

I would suggest that be best solution is to carry a can of Fix-A-Flat, a few plugs and a small 12v air compressor. That's similar to what went into the Z06 as that car didn't come with run-flats as OEM tires.

Even finding a decent low-profile jack could be an issue. Try completely deflating one tire and then measure the distance between the ground and the bottom of the frame where the hole is for the "hockey pucks". That will determine the minimum height of the jack pad.

You would also need a 1/2" drive breaker bar that's something like 18" long, a 6" extension and a deep 19mm socket. If you have a set of locking lugs, make sure that you have a 1/2" drive socket of the correct metric size to use the special wheel lock socket.

Not sure what GM planned, but the larger center compartment in the trunk was designed in to carry a spare just in case the run flats didn't work out. Why not just pick up a single used spare wheel/tire like you already have on the car rather than a steel wheel that might not fit. Since you are not storing it in the car the size shouldn't be an issue.

You guys did notice the OP already has "inflator can, plug kit, and mini-12V compressor" in the car, right?

David Shiel

which put the issue in perspective for me. So, here is my conclusion after absorbing it all:
1. Keep the USAA Road Service. Cheap at $12 a year and excellent when I have used it.
2. Update my inflator and carry two (was in car when I bought it)
3. Keep, plug kit, lug and lock sockets and breaker bar and the 12V pump I now have.
4. Add a sturdy needle nose plier to go after imbedded nails, etc.
5.On road trips, carry a small scissor jack or some such.
6. And, critical, check tire pressures often.
So, again, thanks to all for the input!!

And, Happy New Year to You and Yours!

Why not just put run flats back on

I have wondered about the spare tire situation ever since moving from a C4 to a C5. I have runflats. I also have an extra front and rear wheel and tire in my garage that I could have someone bring to me if necessary.
What do you think of this? Take a front wheel (17") and mount a
245 50 17 tire on it. The circumference is only .05 inch smaller than a
245 40 18. It could be used on the front or the rear? A friend of mine has this and carries it with him.

lies in my experiences with run flats. I have inherited them on two cars. The best I can say about them is that they were crap! Likely due to side wall stiffness, they rode like a buck board, and both sets were very loud and annoying. I replaced and scrapped both sets, though they had thousands of miles left on them. Will never waste my money on them.

Now, I realize one does not buy a Vette for ride quality, as I have owned several of most generations since C2 to C5, but why ask for annoyance? I always marvel at the comfort of my C5s with AS tires.... that for a performance car.

Now , we have entered the realm of personal and subjective opinion, and everyone has one. That is mine, and I'm sticking to it. No need for further justification.

SEE POST # 8

Based on great input here, I have arrived at a spareless solution.
Thanks,

run flats suck as well as being hard, poor ride and handling compared to non run flat tires and zo6 don't use them......to each their own. GTO spare as well as GTO stock rim will work with minor opening up of center for hub fit, also no room, at least for zo6 of stock rim especially the rear in the drop down area in trunk. I use that area for small jack, 1/2" braker bar+socket and an approximate 12" 1" thick board to drive up on to give clearance for jack placement and of course tire plug kit and inflater kit...good luck and hope the flat gods keep you flat free.

I picked up a GTO spare years back when a rail car of GTO's derailed near Oklahoma City. I immediately tried it on my FRC and discovered the hub would not fit over the Corvette hub. Minor opening of the center hole on the wheel and it fits just fine. Wheel is lug and hub centric so it is not an issue. It fits on the front and rear.

Good luck... GUSTO

I currently have a small scissor jack.

Now I know you're a smart guy (you tell me so) so I know you would have never forgotten to see if you have wheel locks and if so that you have the tool to remove. Better check that it is the correct size since I have been told your nuts may not be as big as most.

I agree you better keep the AAA service because I doubt that Vicki is going to schlep a wheel and tire over to help you out at the strip club when you have a flat.


Mr. Sam, as always with helpful advice

huesmann

What model is it?

David Shiel

Thanks for the advice. Dang, I went out and checked my nuts and darned if they haven't shrunk a bit!! We are supposed to get shorter when we age, but oh no, not the nuts! Vicki wants to hit a local strip club with me, so I think I can bribe her to bring a spare to me there. Maybe not so much to a girl's apartment, though.

As always your learned advice is appreciated.
Dave

Love you too buddy but not like Vicki.

Any experience with the 2006-2011 Cadillac DTS Spare fitting. Looks like the GTO space saver.
