My wife and I just picked up an IS350 Blk/BLk w/ Sport Package.
This is a NY car and will have to battle winters so I needed to change tires from the summer set.
Can I get away with 225-45-18 in front?
I wanted to soften the ride at the same time, roads are pretty rough here in Long Island, need advice!
Thanks,

That is correct. I am also running 10mm spacers up front. It is close to rubbing, but never does. If I didn't have the spacers, it wouldn't even be close to rubbing.

This is what it looks like just after I lowered the jack. If you cut that fender gap in half that is what it looks like after the spring settled back in. The front appears to have about 1/4 inch more fender gap than the rear does so it is far more even now. I would say with a 225/40 the difference is about 1 inch so it really helps to even out the looks. Not to mention I have almost eliminated the understeer, the car handles way better now.
You can tell by looking at the front compared to the rear that the front is a little shorter, but the sidewall profile is almost identical from front to rear. i don't like having the front stretched with the rear bulging. This evened things out, helped it ride smoother, and handle better.

SinCity: Were the spacers necessary to avoid rubbing on the strut/fender liner (ie the inside, not the outsider fender)?
Oblivionia: The 225/40 has a tire radius of 12.5" while the 235/40 has a tire radius of 12.7". The 225/45 has a tire radius of 13" so that may be why yours was rubbing.

Are you using the spacers to get the tire to sit for a closer to the lip look of for a different reason? You could probably run 245-40-18s up front without spacers and not rub.
