Hi friends,

I'm in the market for a set of Snow Tires + Wheels for my new '22 WRX Limited.

I'm set on the Bridgestone Blizzak WS90 tire; just need to decide on size.

Below are some questions for ya -- along with some notes/images that I've gathered from the internet.

Appreciate your help!

Cheers,
Jon

QUESTIONS
  1. Which size Snow Tires / Wheels do you use? Can you share a pic of how they look on your car?

  2. I read that narrow tires aren't good if you don't have Studs -- is that true?
    Narrow tires and studs = good
    Narrow tires and no studs = not so good

    When you don't have any studs to reach down into the ice below the top layer of snow you actually want a large contact patch in order for all those little groves and blocks of the tread to grip as much snow as possible.

OEM SPECS
The '22 WRX Limited factory options are as follows (both come with Summer Tires):
  • 17" 235/45/17 tires on 17x8 wheels
  • 18" 245/40/R18 on 18x8.5 wheels

TIRE SIZE OPTIONS [ Rolling Diameter ]
  • What I have:
    • 245/40/R18 [ 25.7" ] w. Summer tires
  • What I think the two best Snow Tire options are:
    • 225/50-17 [ 25.9" ]
      • Pros:
        • 225/50 has a rolling diameter within .1% of the 18s that I have; so I'd think I could use one of my snow tires as a spare if I ever had to.
        • More ground clearance
        • Narrow tire supposedely better in snow?
      • Con:
        • Narrow tire not great when not in the snow
    • 235/45-17 [ 25.3" ]
      • Pro:
        • Once the roads dry up you will get better performance out of a wider tire.
      • Con:
        • Reduced ground clearance
  • Other snow tire options that one could consider:
    • 225/45-17 [ 25.0" ]
    • 215/50-17 [ 25.5" ]

i'm runnin 235/45R17 and they kinda suck. car wanders and dont track the same. i think too much sidewall.
tirerack tries to keep diameter the same at the expense of adding 2" of sidewall lol. i miss my summer tires already.
again, 235/45R17 SUCKS for handling
@22Rex_Red Handling bad in the snow with 235/45/17? Or just bad for normal/dry conditions?

Appreciate all the replies folks!

I got the Bridgestone Blizzak ws90 same size. I could have went up a size maybe but didn't think about it. It still hasn't snowed so as for how they handle I can't comment. They look good. I recently saw another 22 WRX sporting the same tire and size. I guess they are popular with WRXs
Agree these 245/40/18s look good — but I’d have to think not the best handling in snow.

@Drama.308 you’ll have to let us know how these perform in the snow!

bad on normal dry, car wanders left/right after putting on 235/45/17 at highway speed. the oem summers did not wander at all, drove straight as an arrow with 245/40/18s . i think it's the huge sidewall of the 235/45/17
have not had a chance to test them in the snow (yet)
@22Rex_Red Did you have the snow tires put on by a shop? Did they do an alignment / balance check?

One of my friends runs 235/45/17 on his WRX — and he says they’re great.

In snow it has a good amount of lateral grip, on dry pavement when you are pushing it the rear end feels twitchy but overall I am quite happy with this setup.
@Gramser57 what do you mean by, "rear end feels twitchy with the 225/50/17s on dry pavement" -- like when you turn it doesn't feel like there's enough traction?

Wonder if I'd be better off with 235/45/17s then -- so dry pavement driving feels good too?

Heh, I called Subaru Corporate and they said they can't make a snow tire recommendation; and to contact the dealership.

And the dealership said to contact Subaru Corporate.

Turns out nobody at Subaru has knowledge of what the best performing snow tire size is for the '22 WRX.

It feels like the rear is quick to rotate when you make fast steering inputs whereas the stock setup the rear rotation is more gradual. I would say for dry pavement its obviously not as good as OEM 245/40/18 just due to the taller sidewall, and less contact patch.
@Gramser57 Ahh, yeah I could see how that might get annoying for long trips.

I only really need 'em for Tahoe; and 85% my drive is on the highway from The Bay Area.

So perhaps I'll just stick with 235/45/17s; reduced ground clearance compared to the 225/50s -- but less fishtailing on dry pavement.

... though Poll results have 225/50/17 in first place.

I’m pretty much set on 235/45/17.

I'm looking for steel rims/wheels, ideally in 17x7.5; but can only seem to find em in 17x7.

The perk for going with 17x7.5 or 17x8 is that the wheel could fit up to 245/45/17 tires; so I could go with a more wide tire later if I don't like the 235s.

Basically a wider wheel just means less sidewall and more tire size options, right?

Today I learned the Load Index for '22 WRX Limited needs to be 97+.

Subaru Owners Manual:
Image



The Blizzak WS90s I was looking at are only 94 load index for 225/50; but the 235/45 Blizzak WS90s are 97.

So now I'm thinking I'd go with Vredestein for the 225/50 and Blizzak for 235/45:
1. Bridgestone Blizzak WS90 SIZE: 235/45/R17
2. Vredestein WINTRAC PRO - SIZE: 225/50R17


Also, the only STEEL RIMS that I can find are 17" x 7"...

And this Tire/Wheel Size Calculator suggests that a 17 x 7 wheel would only work with 225/50/17; for 235/45/17 it says the suggested wheel size is 17x7.5 - 9.
  • TIRE SIZE: 225/50/17 | Wheel Size: 17" x 6" - 8"
  • TIRE SIZE: 235/45/17 | Wheel Size: 17" x 7.5" - 9"
I'm actually now worried that the 17x7 wheel might be too small for the WRX brakes; since Subaru manual recommends 17x8 as the smallest wheel.

I'm going to Wheel Works tomorrow to see if the 17x7 steel wheel even fits over the breaks.

Here’s how the 17” x 7” Steel Wheels look on my ‘22 WRX Limited.

Tire shop says they fit okay, wheel spins with no contact to caliper or rotor.

Are they right? Is it okay for there not to be a lot of space between caliper and wheel?

I believe this wheel will work perfectly with the 225/50/17 snow tires.

Just installed snow tires and wheels!

Total cost out the door was $1,700 — tire pressure sensors are expensive! $90 each!

I went with 225/50/17 Vredestein WINTRAC PRO tires and Pacer 17” x 7” Steel Wheels.

They balanced the wheels by placing weights on the outer lip, which I think looks pretty silly. I told them I’d be back to have them re-balance on the inside of the wheel.

Here’s how they look on my ‘22 WRX Limited:
