I have a 2009 G37X-S with stock 18” wheels. I’ve been running all season tires, but I’m taking a new job where I’ll be frequently driving from Denver to Colorado Springs and back. This can get snowy and icy, so I’m planning to buy some dedicated snow tires. I’m thinking about Blizzaks or Nokian Hakkapalita tires.

I have a line on some Q50 wheels:
17” x 7.5 with a 45mm offset.

Will these fit my 2009 G37X-S? I see other G37 sedans running 17-inch wheels, but are the brakes on my S model bigger, requiring 18-inch wheels?

Ended up with some 18" aftermarket wheels with Blizzaks.
