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" ]

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.

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:

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.

I'd think twice about that. I did that once after being warned, and sure enough it had a slight vibration at certain speeds. The shop rebalanced allowing outer lip weights and it ran perfect. I believe stick on weights don't work on the outside edge of some wheels, but I could be wrong.

Advice needed.
I live In st louis, and I make 2-3 ski trips to Colorado A yr. This yr I’m crusimg British Columbia for a few weeks. And then down to,Oregon, and Co., 6000 mile ski trip.

the stock Dunlop’s need to go, but I’ve had a blast with them. They only have 6k on them. I’m not worried about running conti Dws 06 in Colorado, but the bc trip has me thinking dedicated winter tires, and rotate the dunlops for a couple of yrs.

I think I’d get the same mileage out of either choice. And I think paying to swap is good insurance from an accident in winter and worth it to drive summer tires.

what Say you? Dws and sell the dunlops for a few hundred, or dedicated winters? They’d be handy even in at louis 4 months a yr.

I won’t get separate rims, I’ll be getting a new car in 3 yrs anyway.
