I am working on purchasing a winter setup for my 2011 CTS-V and wondering if 18" wheels will fit on both the front and back. I found in shopping around that a set of 4- 255/45/18 on 18" rims is much cheaper that a 19" setup. I have the bolt pattern and back spacing all figured out, just need to know if they will fit!

Yes, but maybe only certain ones. I use Moda 18s, and they fit the front just fine. Check out wheels for a Pontiac G8 since I used mine on that before the V. What offset did you figure out? You'll need at least an 8 1/2" wheel for 255s too. Have you considered the 245/45 x 18? You can get by with an 8" wheel, and have a lot more tire choices and room. Thinner is better in the snow! I'm actually looking at the 235/50 x 18 for this winter since they can handle the load easy enough.

I think I will look at the 245's with 8" in rims. A 40mm offset on 8" width is only 2mm inboard of the stock wheels with 24mm of extra inner clearance. Thinner in the snow is better for sure, exactly I couldn't bring myself to put a 285mm snow tire on the rear (especially for the price).

I have a set of Touren TR9 wheels in 18" with some Nokian Hakkepellita rubber in the sizes you mentioned. The dealer I got the car from had ordered them and sold them with the car. There is very little clearance around the front calipers but no rubbing. I install them in case my truck decides to break down, but prefer not to drive around with studded winter tires.

I have the same as the guy above; 18" x 8" with 40 MM offset.

OldChevyguy, which model # of Touren TR9 are you using? Offset and size please? None of the dealers around her want to order wheels up for me that technically don't fit according to their lists.

Ended up purchasing a set of 18x8 40mm offset Drag DR37 in Flat Black mated with 245/45-18 Hankook I Cept Evo's from Discount Tire Direct. They fit up and look great. We shall see how the Hankook's work when the snow flies...

Any reason you went with 18x8 and 245/45 instead of 18x8.5 and 255/45??

Skinnier is better in the snow. Here are two crapy pics taken with my blackberry. The picture of one fit to the front doesn't do it justice. I don't think it looks good in the picture but does in person...

I will take a few better pics this weekend and post...

Im looking at doing the same, but I am looking for cheap, real cheap, like used wheels off a BMW/Corvette/ETC. How did you figure out backspacing and from what you purchased it seems that 40mm will work for both the front and rear. I figure as long as the wheels I find have a backspacing of 40mm or larger I can always put a spacer in to bring it back to 40mm. What about the hub bore, did you have to worry about that or did you just stick with bolt centric wheels? On the tire size can you go with a larger aspect ratio to fill in the wheel well a bit more? I have a V wagon 2011, are the specs the same? Thanks.

If you buy from DiscountTireDirect, hubcentric rings and lug nuts come with the wheels. All delivered from under $1G...

How about TPMS sensors? I couldn't find them on the Discount Tire website.

Dude, get the Touren TR9 rims in 18" size, they will work and they're about $139 each. You'll need hub ring adapters and smaller nuts but a good shop will include all of that for you. Just make sure they put the wheel balance weights on the inner side of the rims and not near the brakes or they will rub, there's very little clearance.

Hmm, I will have to consider them. I couldn't do nearly as well as thebigjimsho, not sure how he got the set with tires for under 1G. I was looking at camaro 2010-2013 steel wheels for 150$ for the set. It looks like all I need is a wheel spacer, the diameter clears, lug pattern works, and hub seems to work. The front face of the caliper hits the inner of face of the mounting surface on the wheel. I have no experience with spacers so I'm checking into it.

No no, I got the wheels alone for just under $1G. I bought the slicks separately...

18x10 with 265/40R18 Michelin Pilot Alpin PA2's are working great for me. In Minneapolis, we got hit with a major snow storm today (6+" of snow) and the package held up just fine on my Vagon today.
