Default Winter Tire/Wheel Setup for Sport and Red Sport

I'm looking into buying a set of winter tires and wheels. I'm pretty certain I will go with Michelin X-ice Xi3, because they worked well on my past G35. As far as wheels I'm looking at 18" size in some options through tire rack, which are basically the cheaper Sport Edition brand wheels or the Enkei Raijin (more money). I have a Costco membership as well and could look at the Velox wheels but am unsure which would work for the Q50S and RS models.

Can anyone offer any feedback on the wheel choices? Also, what size tire are folks going with in 18". Looks like the equivalent size to maintain diameter would be 245/45R18, but that seems a bit wide for winter use. Otherwise, 225/50R18 is better for winter I think, but is 0.7% larger diameter so the speedo would show 51MPH when actually traveling 55MPH.

Thanks,
Damon

Seems like you're going in the right direction. Narrower tires will definitely be better in the snow than wider ones but I think your options are pretty limited. Just want to point out that the speedo will not be affected as much as you think. At .7% difference, speedo showing 50 mph will be an actual speed of 50.4 mph. At 90 mph on the speedo, you'll be traveling at 90.7 mph.

I went with the Enkei Raijin. I like them a lot. Also have the X-ice. Super fun tire in the snow. Great grip.

Alpine Meadows ski area in Tahoe. Mid-march this year. We had a lot of snow.

LOL, you're right. I of course used 7% difference instead of .7%. That's what I get for cranking through this on a quick lunch break.

Awesome pic Sinecure!

Check the tire specs on tirerack, they can vary between brands/models, even
if they are the same size. Tread depth, width, revs/mile, etc. will vary.

The OEM SP SPORT 5000 DSST CTT P245/40RF19 is rated at 782 revolutions/mile.
X-ICE XI3 225/50R18 (10.5/32" tread depth) is listed as 774 revolutions/mile.
Blizzak WS80 225/50R18 (12/32" tread depth) = 775 revs/mile.

X-ICE 225/50R18 vs OEM = 1.0% difference. Still not very significant.

Look at Nokian as well, they'll cost a bit more, but arguably one of
the best you can get:
https://www.nokiantires.com/winter-t...kapeliitta-r2/
Hakkapeliita R2 225/50R18 (12/32" tread depth) = 776 revs/mile.

I had Hakka2's on my '93 Sentra SE-R, got 7 winters out of them, and
still had 6-8mm tread left. They had amazing traction in snow and ice,
accel, braking and cornering.
Also had General Altimax Arctic on my '98 Sentra SE -
they were decent as well, but not as good as the Nokians.

Last winter I had new Conti DWS06 on my Q50 Hybrid AWD.
They were O.K. accelerating in the snow/ice, but mostly due to AWD -
braking not nearly as good.
I'm considering getting Hakka R2 this winter.

@Sinecure I see you got your setup from Tirerack. Did you opt for the TPMS sensors through them as well? Also, do you have any side profile pictures of your winter wheels on your car. I ask, because I have an AWD Sport in Iridium Blue, so seeing your setup gives me a great visual for my car!

My current setup is 225/50/18 from tirerack which includes wheels. This was the set I was using on my previous Q60 (G37 coupe) so it was a seamless transition. Im going to be upgrading the tires to a more performance winter tire as I feel my current set just completely makes me lose all feel of the road and I hate that. The new new size I'm getting is 235/45/18 which was more optimal.

Nope, I'm a smart idiot. I kept the sensors from my 14 Q50, assuming they'd work in the 16. Fack no! So I have sensors in there, but they won't talk to my car. I just drive around all winter with the warning light on my dash. I did add a can of fix-a-flat to my trunk in case I get a flat.
