Default FYI & Help: Cadillac CTS Spare Won't Work

I decided to start a new thread instead of hijacking a past thread.
The problem: a spare tire if you run BIG brakes. Up front I have
C6 ZO6 calipers with Fiske 18" rims. Someone smarter than me
realized that if we get a flat tire, the 17" spare won't fit. Fix-a-Flat
won't work if the hole is in the sidewall.

It was said that a 2008-up Cadillac CTS 18 X 4 compact (donut)
spare tire will fit and work. Locating one was difficult since this spare
was only a CTS option. The CTS came with a repair kit including
a mini compressor.

I finally found a CTS spare in Texas. i tried it tonight and not even
close to clearing the front face of the caliper. Diameter is fine. I
would not only need a 1/2" spacer, but have to get longer wheel studs
all around. Anybody have any ideas? TIA!

PS: I asked for Fiske's help years ago and they were of no help.
Maybe now with new ownership I'll try again.

Hi Ted
What would be the problem going with longer studs and a spacer only for emergency.

1/2" doesn't really sound too bad.
I would say try it, buy one stud and some washers (1/2") for trial fit.
Just a thought.
Pete

I hear you, Pete! It just sounds cleaner if I could find the correct
wheel. It must be possible as I have wheels that fit now.
And, I'd have to replace all 20 studs, plus would my current
lug nuts fit with longer studs on my wheels?

The lugs will work,open lugs but the lug covers might not go on the lug nut with the stud coming out the front side.You might be able to -dial in- a wheel stud and get the cover on the nut.Dial in meaning trim the stud until it will work with the cover and still be long enough to use a spacer.

Ted,

Several months ago I posted up I believe a solution to the spare and within minutes a "moderator" had messed with the snapshots, that PMO and I deleted the entire entry.

I have your solution, I've emailed you. You'll need no wheel studs.

Dave,

I am looking at same option since I'll be going to big brakes also. Can you share your solution?
Hope all is well!

what about a wheel adapter and 5 extra lugs?

the adapter would bolt to the existing 5 wheel studs, then the wheel would bolt to 5 studs on the adapter

like this:


Not optimal but neither is a flat

Yes, this style adaptor would work, I just thought the compact spare would
be a "drop in" kinda like a Fluidyne radiator (wink, wink, causin' some fun).

PS: I like "Not optimal but neither is a flat"

Ted: I've got two of these on the shelf - one is available to you.
PM me ...

Wow! Cool! How thick are they?
Have you used them? What do you think?
