Touring's wheel sizes? The 18s.
 

What's the width on the fronts and backs?

F: 18x8? R: 18x8.5?


Thanks.

I believe they're 18x8s all the way around. (They just put different size tires on so you can't rotate them.)

So I would not want to put the stock tires, even temporarily, on a F: 18x8.5 and R: 18x9.5 right?

I mean it looks like the RE40s are already being stretched.

They wouldn't fill out the wheels at all--don't do it.

The touring OEM 18s are 18x8 all around.

The tracks 18s are 18x8F, 18x8.5R.

People have placed the stock tires on the rim sizes you mention, and reported no difficulty although they will look very stretched and display part of the rim edge (i.e. unprotected). I had the same question when I upgraded my touring to the NISMO wheels. I wanted to use up the stock tire since they had so much tread. I got opinions going both ways, but I do remember one member having it done and reporting no safety concerns (just looks bad).

In the end I went with new S-03's. Pricey, but looks better and I feel better about it. Good luck!

Tempting.

I am going to be getting some BFG Geforce KDs soon. So I definitely need to nail down my wheel choice.
