Hello All,
I have recently placed my order for a 2021 Trailblazer Active 1.3L AWD in Midnight Blue, and I was wondering if anyone has seen the specifications for the wheels (rims) on the new Trailblazer. I am looking to start putting together a Snow Tire and wheel package, preferably steel wheels since they seem to do better with the New York State road salt. I would like to be able to just switch them out when the season changes.
Thanks in advance,
Dale

All I know is the base model L has 16" steel wheels, Activ has 17" aluminum and the RS has 18" aluminum. GM hasn't posted the wheel widths, offsets or backspacing. I assume the widths are all 7" or close to that.

Winter wheels are on my to-do list, as well. Like you, the winter tires will be installed onto steel rims. I'll also be sure that the winter wheels have proper tire pressure sensors installed. In the past we've forgone the sensors on winter wheels, but it was a persistent annoyance when the TPMS could not be easily disabled.

I expect it'll cost $1000-1500 CAD for the set of tires, rims, and sensors.

I don't yet know the suitable specifications for the TB winter wheels.

dcbridgwater welcome,
Check discount tire website. You can punch in year make model and it will show you wheels available. 17 x 7 w/ 40mm offset seems to be the most common size to choose from for aluminum and 17 x 7 w/38mm for their steel wheel. I like to shop them right around the big holidays. They usually have good rebates and if you put them on a DT card there is an extra rebate. Plus 6 month interest free financing. When the first bill comes just pay it off. I have done this several times over the years. Rebates you just enter online and in about a month you get a couple of Visa cards to spend. I have found their prices to be very good and in and out in about 1 hour. If you know what tire you want, make an apt and you should be good

Thank you all for the replies so far, I have been checking various wheel retailers and they seem to be all over the place as to what will fit as far as the bolt pattern. So I guess I will have to wait until I get it to see what will fit.
Quaid,
Since we seem to have the same idea on steel wheels, if you get yours before me I would really be interested in you choice of wheels. I will also post what I find.

Thanks,
Dale

Absolutely. We will probably have different retailers (USA vs Canada), but the product selection should be basically the same.

There are seasonal sales here every year, so we'll probably wait for those in ~September / October / November.

These tires are the same brand and similar styling to the all-seasons which come stock on the Activ trim. They are studdable, if you're into that sort of thing, but it isn't kosher for most road driving where I live.

Bridgestone Blizzak's tend to be the most consistently and highly rated winter tires, so I'm leaning towards a set of those rather than Hankooks.

Quaid,
Thanks for the suggestions, I have been considering Winter i*pike RW11 also but giving the Bridgestone Blizzak DM-V2 some thought.
Right now I am still undecided as too which steel wheels to get since my plan is to get a set of 16" wheels and run 215/70R16 tires.
Discount Tire lists different bolt patterns for the Buick Encore GX and the Chevrolet Trailblazer but every thing I see on the ACDelco parts catalog they are the same as far as wheel hub bearing and brakes so I don't understand why the different bolt patterns.
So for now I have ordered 1 wheel in the 16x6.5-115.00 size to see if it fits ok if it does I will order 3 more. If it will not fit I will have to try the16x6.5-114.3 size.

I have received and test fit the one wheel from Discount Tire, it is a Liquid Metal Atom #48998 , size 16x6.5 with a bolt pattern of 5-115.00, 41mm offset and 72mm bore. I should get the other 3 tomorrow.

I put on the wheel and every thing seems to fit OK, I torqued the lugs down to spec and the removed the lug nuts one at a time and the lug studs were all perfectly centered around the rim hole
as well as the bore being centered around the hub. There is enough clearance around the brake caliper and doesn't appear to rub anywhere.
The one thing I am not crazy about is with the 72mm bore and a 70mm hub this set up will be lug centric which must not be a problem since it seems most aftermarket wheels are set up that way.

As far as Tire Pressure sensors ACDelco catalog lists #13522631 for the sensors which seems to have been replaced with #13516165 which I hope is correct since there also seems to be conflicting information on the correct sensor also.

So my winter set up will be,
4 Liquid Metal Atom #48998 , size 16x6.5 with a bolt pattern of 5-115.00 from Discount Tire
1 Wheel install kit from Discount Tire
4 ACDelco Tire pressure sensors part #13516165
1 Set of Swiss Drive wheel covers #508138C from Ebay
As far as tires I think I will be going with the Bridgestone Blizzak DM-V2 size 215/70R16

The hub is 70.3, it is that same a the encore gx and the current GMC Terrain. The bolt pattern is 5x 115

dcbridgewater,
Curious on the choice for a 16” wheel setup? Doesn’t the Activ model come standard with 17’s? I know it is a small difference, but doesn’t it throw the speedometer off? I like the idea of a winter setup. Where I live the roads will be salt and their wonderful beet juice solution covered until spring.

16 inches or 17 inches are rim diameters, which must be summed with tire wall heights to know total wheel diameter.
RS: Kinergy 225/55R18H -> 27.7"DIA x 8.9"W
Activ: Hankook Dynapro AT2 (RF11) 225/60R17H - > 27.6"DIA x 8.9"W
Others: Kinergy 215/65R16H - > 27"DIA x 8.5"W

The winter tires purchased by @dcbridgwater : 215/70R16 -> 27.9"DIA x 8.5"W

Regarding "minus sizing", this is normal practice for winter tires for both performance and economic reasons:

Trail Blazed,
I chose 16" setup because when I get snow tires I like to go as narrow as I can and still be near the original diameter. The wheel size calculators show my speedometer will be about 1 mph off at 60 MPH with the 215/70R16 tires but according to GPS my speedometer is 1 MPH fast with stock tires so with my snow tire setup I should be very close.
I would have liked to have gone with 195/75R16 tires but I was not able to find 6" wide rims with a 5x115 bolt pattern so I settled for 215/70R16 tires.
