Hi Fellas,
I took delivery of my 4BW in late November of 2021, and drove it from the dealer straight to the tire shop. I was not able to find winter tires in both of the sizes needed, so I decided to go with an all season instead, figuring it would be better than nothing. Turns out the tires are not much better than the 4S that come on the car in Chicago snow.

So now I'm thinking I will just get a set of snows for the rear. I'm still having a hard time finding anything in 275/35-18 for snow or winter tires. There is a blizzak in that size, but it looks like it has been discontinued. With some effort, I may be able to track down a pair.

I'm open to suggestions here... I am not opposed to getting a pair of 17s for the rear, as it will open up options, a lot, but I'm not sure if they will fit.

What have you guys done to get some better winter traction on this car? Do 17s fit? If not, what size options work for the stock rear wheels, other than the stock size which has no winter tire selection?

Thanks guys.
 
Best way to find more tire options is to size down the tires. Some run 235/40-18 square or if you want to keep O.E. diameters, then you can run 225/40-18 in the front and 245/40-18 in the rear. Those sizes will fit on the stock wheels, but a dedicated winter set would make everything easier.
 
oh nice, more options in 245/40-18.. same diameter and an inch narrower. Should work... Thanks.
 
It depends what all season tires you are running, as their snow performance can vary quite a bit. For winter tires, You'll likely have to find something narrower for the rears.

And forget about 17s for the rear, they won't fit over the brakes.
 
i have michelin performance all seasons on now... I forget the exact model, but they are unimpressive regardless of road conditions., and not much better in snow and cold than the stock tires.

I wanted to get michelin alpin. I had them on my last car (STI). They were very impressive in snow. I know the AWD helped, but neverthelss. The don't appear to be offered in a size that will fit the BW.

I'm not looking to blast through fresh powder here. Just want some reasonable traction on urban roads that have not been perfectly cleaned, and cold clean asphalt.
 
Get the Alpin 4 then. You can get them in 255 and 265 size. They are a good performance winter that will still retain some of the sporty characteristics of the car. If you don't need a true winter then avoid them. If you do decide you need a true winter then Nokian makes the R3 in 255 size.
 

Winter Wheels and Tires

Maybe @Mirza Grebovic can answer this question, but is there going to be a preferred/recommended winter tire for the Blackwings? I've been happy with the Pirelli Sottozero 3's in the past, and I've read good things about the Michelin Pilot Alpin PA4's, but if there's a specific pairing that's...

I'd be wary only putting snow tires on the rear. The computer will control wheel spin, but you're going to have to deal with turning and braking and the mismatch grip might be problematic.
 
I ran 255/35/18 square all of winter and have no regrets. I ran Blizzak WS90s
 
I put snow tires on the OEM Caddy wheels. I used Bridgestone Blizzak WS90 255/35/18 front and rear, worked fantastic. Recommended by TireRack specifically.
 
Thanks everyone who responded. @dribs15 I searched, must not have scrolled down far enough because I didn't see the thread you linked. Some good info in there after I flittered out all the 5BW posts ;)

Car is at the shop now having the summers mounted. The all seasons will be for sale today. Just need to get them back and measure the tread.

I will be using a square setup for winter, most likely Alpins.

Now in a 4 daily here has me wondering if my old square set up from the SS will fit?

Any reason why these wouldn't work on CT4V factory 18" rims?

These fit. I run the same tires on the factory wheels, but the front size only as a square setup (the rears weren't available last year). No issues, they fit fine.

Hey! Thanks for the info. I got stuck in a situation last winter where I planned to use the winter tires/wheels formerly from my CTS Vsport, on my CT4 BW. The dealer claimed they wouldn't fit (jury's still out on that one), so in a pinch I was forced to put all-seasons on it. They were awful in the winter, and are barely tolerable during the summer. I had no idea you go down to 255 on the stock rear wheels. It appears even 245 would work, safely. I'll be getting a set of Michelin Alpin A4s for this winter, which is what I used for years on the Vsport and they were amazing.

I think I've seen you around town! Surprisingly, in the land-of-Cadillac, there aren't too many CT4-V Blackwing sightings, at least in either of our blues.
 
I was very happy with limited driving on my Alpine 4s on the 4 BW before I changed back to summer PS4s. Again limited time with only a bit of snow driving but they performed well. They also did well in dry and wet including a several hundred mile road trip last April.

My advice is to order them now....don't wait because they seem to be in short supply and can be very hard to get.

Did you put the winter tires on the stock rims, and if so, what size did you use? The Alpins are available in the proper size for the front (255/35-18), and it appears that the same size will actually fit on the rear, but, if I'm doing my math correctly, putting a 265/35-18 (also available) on the rear would actually keep the original overall tire height closer to stock. I'm just not sure how much of a difference it makes or if it's worth being concerned about. 255/35's in all corners would certainly make things easier.

And DEFNITELY, thanks for the advice.... I better get something ordered within the next couple of weeks, even if it sits for another couple of months.
 
I was able to find stock sized Alpine winters and I put them on the stock rims. Did a long trip up to Vermont (from DC area) in early April and they did great on the road (even occasionally at near triple digit speeds)....didn't notice anything off with the speedo...but I may not have noticed. Caddy OEM PS4s are certainly better in the dry...but drop off wasn't hateful.

Many folks do a square setup with good results. I'd go with whatever you can get (stock spec rears were harder to find)

Good luck!

I would definitely recommend the Alpins in a 265 on the rear if you can get them. That was my 1st choice but nothing available, and had to settle for the X Ice in a square 255 setup. It’s not enough tire for the car. When driving spiritedly (without being full throttle) on the 255 X Ice, it’s very easy to have all the driving nanny’s start interfering. I’ve had Alpins on my other cars and it’s a great winter performance tire.
