I've had my 09 rwd about 3 weeks and love it. Winter is around the corner and i'm about to
start shopping for snow tires and rims. I have the oem 18's now and would like to go with 17" rims and a skinnier snow tire any recommendations? Also will downsizing my wheels and tires
throw off the traction control?
Thanks in advance

As you can 'plus' a wheel/tire combination (say, go from 17's to 18's or 19's) you can also 'minus' your wheel/tire combo. TireRack or any other reputable tire dealer can fix you up so as to keep your tire diameters the same (from your current 18's to your desired 17's). The only consideration, to going to a smaller wheel, is whether the brake caliper will have room, which I believe shouldn't be a problem on the STS as it comes with 17's (as the standard wheel).

The narrower the tires you have, the better it will go through snow.

There are tire calculators on the web that will help. That will keep the speedometer more accurate. Narrow is usually better in the snow, but throw in fancy electronics and the stability system may come on early. I wouldn't think that is a problem, but personally I would be paranoid that I am wearing a component out with incorrect tires.

As long as all four tires are close to the same outside circumference, you'll be fine.

For snow/ice, narrower is better.

I hope my DWS 235/18/50 will do ok in this coming winter on my RWD
I don't have my own garage to have dedicated Summer and WInter tires

I realize skinnier tires are better in the snow, thanks, which is why I'm asking. Has anyone here tried it with skinnier tires? What sizes work?

Everyone is going to recommend you to follow tirerack's recommendation since it will give you the size meant for your car and options.

Tirerack recommends maintaining the same width as oem which I am trying to avoid.

Anyone knows what tires these are http://www.gminsidenews.com/forums/f128/winter-wonderland-2011-cadillac-cts-v-100212/ .. It says Pirrelli's but doesn't say the exact model.

Any tires designed for snow will out-perform All-season/Summer tires on RWD models. All-season's are fine on AWD's. With rare exceptions, the roads will be clear most of the time.

IMHO, Blizzaks are a bit noisy on dry pavement and the DWS is nicely matches my preferences. That doesn't mean it is the right choice for someone else. Opinions vary for good reason.

Have fun!

Have fun! Do you wear your DWS in the snow?
How does it do for you in the rain?

DWS on a AWD work fine in rain & snow. In some climates, they might be OK on a RWD but we get too much snow & ice here in Wisconsin. That's why my wife's car gets the Blizzaks.

Ah true, yea DWS on my RWD handles pretty well in the hard rain better than what I thought it would and its ok in light snow.


I found some Pirelli 240 Winter .. 2 tires brand new and 2 with a 8.5/10 thread left .. for like $583 but the size are 245 40 18 .. I currently have the same size as you 235 50 18 all around, how will a 245 40 18 be or would it even fit on our cars ?

I am def trying to get some LM-60 ow Pirelli 240 Winter if I find them cheap.

IMHO, 245/40R18's are too small. I like an accurate speedometer. With 18" wheels, my car gives me a choice between 255/45 and 235/50 unless I have the VSS recalibrated.

I really like the DWS, since we can tell about the thread life according to the D, W, S letters printed on them.

What would you guys recommend for winter Blizzak LM-60 or Pirelli 240;s ? These seem to be the only top snow/winter/rain tires that come in our size 235/50/18 or even 255/45/18

Blizzaks are excellent tires. I use LM-22 (no longer available) in Chicago.

My wife loves her Blizzak's in the Winter. She has a RWD with the 235/50R17 setup but we don't know how the Pirelli's would doI

I run Conti DWS 235/50R18's on my AWD year 'round. They provide a very nice compromise that suits my preferences.

I am going to stick with Conti DWS 235/50R18 on my RWD as well until I find either the Pirelli 240's or Blizzak LM-60 then since I am trying to get a real dedicated Winter but not trying to pay full price right now lol. I actually read a great review on a CTS-V RWD in a Snow Storm how it performed with Pirelli's snow tires but they didn't provide the exact one but I am guessing it was 240 since its the top winter tire.

I think all-season tires are barely adequate on a RWD STS in climates with a real Winter. Summer tires are also superior when the weather is hot. One of the great things about AWD is that all-season tires do become a good alternative.

Yep, even though I was ok in snow and rain with my DWS I still know it wasn't as good as it would be if it was DWS on a AWD.

A RWD with Blizzaks mighthave superior go-power to an AWD with lesser tires; better braking for sure. Anyone ever drag race in snow?

Some fun is ahead!
