I have 16x7 TT2s with 4" BS on them....in the sig pic below.

Here's how they fit running 215/55-16s. You won't have any problem with the inside clearances.



The problem you could run into is the width of the tire. 245/45 is a smidge wider than my 215/55 and a little shorter. I alread have had my rear tires hit the wheelhouse lip on a deep dip... I've decided to roll my fender lips. I think you can run these, but you'll definately have to roll the fenders and rear wheel houses.

245s can fit up front...
I run a 16x8 rims with 245 45-16 tires up front.
It does require a little work though

Matt's right..you can run 245s up front..but you're getting into fender issues. Mine scrape the fenders when I make a dip/turn running the 215s.

Again...235s or 245s, even with the lower profile will be problematic in the back. You'll need to roll your fenderwells.
