Looking to purchase a Doughnut Type Spare Tire for a 2005 CTSV. I do not know the Bolt Pattern for the Wheel but the Wheel should be a 6 Bolt Wheel and a 18 Inch Tire. The car did not come with a spare tire. I saw a Cadillac SRT-V8 with 18 inch Wheels on it and it had a 18 Inch Doughnut Type Spare wheel and Tire underneath the Rear Body and the Wheel had 6 Holes. I don't know if the bolt pattern is the same.

I think he's referring to the SRX. I don't think that the SRX spare will clear our calipers. A lot of us who ditched our run flats picked up an extra rim and mounted our least bald run flat on it so we could have a full size spare. Some have even gone so far as to get the CTS jack and tire tools from GMPD.

Ebay can get you the spare rim, search ("Jack" in CTS-V forum) can get you the part numbers for the jack and accessories to order from GM parts direct if you so desire to go that route.

Never heard of that one before!!!!!!!! Buy an extra factory wheels and an extra tire. Put it in the trunk and be done w/ it.

As of this moment there is no confirmed (with pics) or even rumored/suggested "doughnut" spare that will fit a CTS-V. This due to offset, clearing of brake calipers/rotors and balance of rim and rubber.

Just get a real spare and throw it in the trunk - it fits!

I would also like the doughnout. A regular spare would add weight that I could do without..ya know?

I bought an adaptor that bolts to the CTS-V hub and converts to any 5 bolt wheel. What we need is a temp spare with a 16-18" rim. THe stock CTS donut doesent fit. It hits the caliper. I havent had time to fish for another wheel.
As was said, you can use the stocker but its heavy along with the jack.
A donut would be nice.

Would an adapter that moved the wheel out give clearance for the caliper on donut type rim? Maybe someone with the specs on our wheels could check with a company that make s adapters/spacers like http://www.wheeladapter.com/default.asp

The adapter pushes the wheel out 2.5" its nowhere near enough. The ID of the rim is too small.

Seems like someone would make something to work. I'm sure they would sell a few!

If a spare tire is 2 much extra weight I guess you ride solo, huh!

I'd buy a donut spare if one became available. I don't like the idea of stuffing a big high dollar wheel and tire in the trunk.

For those considering non-runflat tires, just remember that there are alot of car nuts just like us, changing perfectly good tires at the drop of a hat. When I got my Toyo T1Rs, I gave the tech guy my extra wheel and $20 and he mounted a nearly perfect radial in stock size for my spare well. There is no need to pop for a 5th high dollar tire. Plus, forget the cheezy jack and get a AAA card. Life is too short to change tires.

Those hideous doughnuts do save space and they are lighter. But seeing one on a V? The horror!

not to mention it cuts into cargo capacity during road trips. I cannot even deal with it around town as I have my bike with me in the trunk witht the seats folded down more often than I don't....

...it cuts into cargo capacity... Nope. You put the spare in the recessed area underneath the trunk floor ... jack fits there, too. Up here where we have to go with A/S tires in the winter, I'm planning on just using one of my F1s on stock rim as a spare with Avons for winter installed on a set of Mille Miglias. Dreamin' posted a beautiful exploded view of what you need for the spare. Check it out on FAQ. I do agree, though, a doughnut would indeed be the berries.:worship:

It won't fit in there perfectly, i have drag slicks on 2 of my factories and I usually put one in the spare tire holder and the other behind it in the trunk. The cover will not go over the tire.

Thanks! that's what I/we thought - I assume you tried the 18" wheel?
