Wheels for CT5V

Andrew1127 said:

Yeah, I was in a situation where I had to toss winter onto the stock rims because I got the car right off the truck (I didn't order the car, just took someone's order since they backed out) Worked out though because I wanted to get some black wheels and they couldn't get a OEM set in black. I'm only like a hour+ south of Ottawa. Had no issues with the heavy snowfalls this past winter, but 18s would be great for a bit of more meat for the potholes.

I'm excited to get my summers on with the black rims and see how it looks, I'll post some pics up when I get them on, tires should be in next week, then just gotta get them balanced and mounted.

I'm in Manotick, so probably not that far from you. Out here, 19s would be fine in the winter - the worst potholes are in the city itself.

I'm in Quebec and my stock 19's on winters survived the crappiest roads in Canada without any issues.
245-40R19 have massive sidewalls for what they are honestly.

(Better than the 235-40R18 that were on my previous CT4-V, and even those, survived the same roads without any issues.)

I never downsize cars in the winter personally as the OEM wheels always end up being the "winter wheels".

Thanks for the feedback.

FWIW, a friend of mine just bent a rim on his Golf GTI while in Gatineau a week or so ago - he had just put on the summer alloys. He's getting the wheel repaired but he knows that in all likelihood he'll have to buy a new one.

I recently ordered a CT5V but don't have a build date. Regardless, I don't expect my car before the end of the summer and am kind of torn here - my brain tells me to get 18s for the winter and keep the stock 19s for summer duty as I don't think a 40 aspect ratio on the stock 19s would do all that well on many of the roads up here (my city - Ottawa - runs its annual pothole festival from February to May every year). But I am tempted to go with nice aftermarket 19s for the summer and keep the stock 19s for the winter.

Did others in snowy areas consider 18s for the winter?

What 18" take off's are you referring to? I'm pretty sure the V only came with 19" and 20" depending on the package. Not to say an 18" wouldn't fit, of course. If an 18" from a different trim CT5 fit that'd be awesome.

A non-V such as a premium luxury. They're out there.

There's definitely some on Canadawheels also. My biggest concern would be fitment over the rotors and brembos. When I clean my wheels, the calipers are pretty damn close to the wheel's barrel that it's hard to clean between the rotor and barrel. If your ordering from somewhere make sure you get guaranteed fitment/good return policy incase their is an issue is probably the best way to go about it, hopefully you get it figured out way before winter so you aren't forced into doing anything you don't want.

Got my tires today, and found a shop that's gonna squeeze me inbetween jobs and get the tires and tpms sensors on my BR14s. Will post a pic when I get the car picked up tomorrow... Maybe after I give it a good cleaning too lol gotta make those photo shoots count.

Weighed the wheels and tires too. Brand new PS4S run flats came in at 31.8lbs, and BR14s came in at 22.4lbs. I'll give the winters + stock rims a weigh when they are off. Obviously not a good comparison for obvious reasons, but I'm sure as hell not ripping tires on and off just to weigh the stock wheels lol. If anyone does take their tires off the stock rims let me know what they weigh out of curiousity!

Yeah that's an important point. I don't know what kind of caliper clearance is required on the V. I might just stick with the 19s as the winter wheels and look for different 19s for the summer.

From sources that I've read, the non-V 19" and 18" standard wheels are 8.5" wide with a 29mm offset and the V 19" wheels are the same. Also GM parts site I use lists the V among those trim levels for the fitment of an 18" non-V wheel.

And we know that parts sites never get their fitment lists wrong...

Lol if they gave you a vin already you can just call your dealership parts department and confirm 18s will fit with your vin. With all the websites showing 5x115 Bolt pattern and only odd ones showing 5x120, I called my dealerships parts Dept to get them to get m exact wheel specs based on my vin.

Good luck, and hope you enjoy your car when you get it.

I don't even have any confirmation that GM has accepted the order. I have plenty of time...

Got the tires on, stock rims and winters weighed around 62-63 lbs give or take. So pumped lol.

Looks really good 👍

Looks great !

Thanks! Wish they made our cars have less wheel gap, lol maybe they left it that big so the cars with 20s look mint ahah

20's still have the same overall height though !
You'd just have more wheels, less rubber, but the same wheel gap.

Blackwing's front size too, but the rear size is nearly 1in taller than the "regular" V's & their front size.
Though, they appear to have a lower stance none-the-less, so surely different springs.

I wonder if the "regular" V's have different spring height between the AWD models and the RWD models.
Since typically, you want more clearance in areas where you need AWD.

You think the 20" rims have a smaller ratio (I know if you upsize yourself you try to match OEM size or you have to get the car recalibrated for the speedo and odo)? Damn that'd be dicey to drive on with how shitty roads are ahaha.

Well, in reality, 255-35R20 is 0.3" taller than 245-40R19, but on the car, that's just a 0.15" difference in "wheel gap" and 0.15" more in 4x4 stance.

So pretty negligible. But you do have 0.7" less sidewall, so on the roads, they would be more prone to damage on our beautiful Canadian roads !

Yeah. I think I am going to take delivery of my car and drive it stock for the first winter before I decide if the winters are going to be 18s or 19s.

I'd say base your choice on what you want to do with the stock wheels since the 19's have plenty of sidewall already.
If you like em enough for summer bling bling, keep em and get 18's for the plushier ride.

If you don't want to keep the stockers for summer bling, then, keep them as winter wheels & buy new 19's (or 20's) for summer !
(Careful to get at least 8.5 wide & 35 offset, so the stance is similar, since stock wheels have 8.5 & 29, anything less will be more inward and less aggressive. This is why I went with 9.5 wide & 35 offset, this gives me a 7mm wider stance, and room for 275's once the stock tires are shot.)
