spare rim/tire won't fit..

1845 Views 22 Replies 14 Participants Last post by  darkman
Received and installed a spare rim with Dunlop 9000 (245/45/18) last night and the sucker was about an inch too high. I can get about 2 turns on the plastic "nut" that holds the spare cover down. I viewed the install pics from CadillacFAQ site and that looked like it fit just fine. Am I doing something wrong?

Re: spare rim/tire won't fit....WTF

Did you take the tub part and the insulation out?
Re: spare rim/tire won't fit....WTF

Strap it to the roof.
I have a 245/45/18 GSD3 in there, and it's about as you describe, although I can turn it down about 10 turns. It definately sticks up about 1/4".

As a side note, I have a trash rim, on which my spare is mounted, so I have the 'outside' of the rim farcing down, as I don't care about the finish. Do you have your's facing up?

Botom line is either:

1) Find an 8" mille miglia, and get a 225 tire
2) switch back to RF's
3) Live with the small gap

dude...if I didn't take the tub out, you guys would be surprised if I had gotten the top back on ; )

and the 3 patches of dynamat looking stuff is so thin I didn't think it would make a difference. Guess its just too fat for the hole.... I have that problem a lot.

Chris...thinking I'll have whats behind door #3. Oh well, I'll play with it tonight and see if I can clear a little bit of room.

Mine stuck up quite a bit too until I flipped it over. You will want the rim finished side down and the top cover will fit a lot more snug.

If it is already outer side down, you probably will have to live with it.
Millie wheel with 245/45/18 tire fit just fine as posted.

I ordered a spare from here, and it only fit outside down. I don't have the jack yet, but Caddy service can take care of that. So it will scratch? Maybe I'm just really weak, but it was heavy and cumbersome to get in the hole. (Being serious, all the pervs- cut it back.)

I'm sure you do.

I'm glad I have a junker for a spare, and don't care about it, as it has really gotten scratched up due to:
  • Having it 'upside down'
  • Getting a scissor jack to fit in there
  • fitting in a lug wrench.
  • Fitting in some jumper cables
Getting all that to fit 'nicely' was not easy. So I have to live with some scratches. On an upside though, I have the emergency equipment I needs, without run-craps and still have my whole trunk to stuff bodies or golf clubs in.

I have no comment about your inability to get it into the hole.

Damn, I wish someone had mentioned this before I bought a spare with a GS-D3 mounted. With the wheel facedown (no padding underneath) I can't even get the lockdown nut on, and I'm nearly an inch over the floor. Useless. Oh, and why do folks keep asking if you took the tub out. On my '05 at least, the tub is divided, so you can't fit a full size spare in there without removing it, making that question moot.

Now you're saying use a narrower mille maglia wheel as a spare. Those were like $120 at Tire Rack when they discontinued selling them.

How about changing the FAQ to reflect that certain stock size tires have no chance of fitting in the tire well. To not be able to put the cover back on (flush with the trunk floor) kills the whole idea of an onboard spare.

I wonder if you can deflate a GS-D3 to get it to sqeeze down under the cover, and then carry a cigarette lighter inflater if you ever need the spare.

why don't you just buy the V carpet trunk liner. You won't barely notice it.

The GS-D3 has unusually wide shoulders. A worn F1 or some cheapy touring tire will do just fine. It's a spare, so just get some rubber on that rim and you'll be fine. In fact, getting a 235 or 225 tire may even be cheaper and will fit even better. The rim is narrow enough.

As an FYI, I have a 2/3rds worn GSD3 (245/45R18) in my spare tire well on the junker rim, and it fits. Barely, but it fits.

Thanks, I thought that was probably the case. I'll try letting out some pressure and seeing if I can squeeze it down. I can't remember the exact language used in the FAQ, but perhaps it should be amended to emphasize a narrow shouldered tire for use as in the spare well vs. a well worn tire. Diameter wise, it seems there is tons of spare room.
