Note that Jedi54 properly cited 245x40x18 and not 245x45x18 (45 being the stock aspect ratio).
You need to go with the lower aspect ratio (sidewall height) of 40 to prevent any fender rubbing fore and aft with a stock suspension height. If your suspension is lowered you might have to go with 35's and/or roll the fenders a bit.
Stock rims are 8" wide and therefore can go to 245 width as the maximum.
btw: and I usually hate to do this, but this subject has been covered MANY times and a simple search would have just as easily gotten you the confirmation.

good catch Huey, but c'mon...did you expect anything less of me? ![Wink](https://www.rx8club.com/images/smilies/wink.gif)
245/40/18 will fit even if you're lowered, as long as it's not some ridiculous drop. I'm running Konis + S-Techs and no rubbing.![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
This tire size calculator will also show that the 245/40 is a great choice
