Winter tire/wheel package for Z435is

The Tirerack website suggests both 17" and 18" winter wheel/tire packages for the 335i, the 335is, and the Z435i, but only 18" combos for the Z435is.

Any reason I would not want to use a 17" winter wheel/tire combo on the Z435is? Isn't "minus sizing" supposed to improve control/traction?

Thanks,

I suspect you may have trouble finding 17" wheels that will clear the brake calipers. However, I didn't realize the brakes were different on the "35is" model compared to the "35i". Are they? I would go with 17s for the winter if you can find wheels that will fit.

Yep, I found it odd that both sizes were recommended for the 35i, but not the 35is.

My interest is in whether I can use the 17" winter wheels/tires I currently use for my 335i on a Z435is.

MStevens runs 17" Moda R1s as winter wheels on his 35is.

Not an "is," but I used by previous 17" set-up from my e92

Ahhh, but 18s are so supersexy!
To be honest, I had really good results through last winter in NY with my 18s, only issue may be higher cost, and more likely to get damaged on a hard pothole hit.

Thanks to everyone for their replies.

OK, mstevens 17" wheels seems to fit. Is the wheel ID the only thing to worry about for brake caliper clearance? Does the width (i.e., 7.5 vs. 8") matter?

Yes, I agree that 18" looks better! I bought my 17" while under the impression that they would provide better traction/handling in snow (the snow driving performance was actually a lot better than I expected).
