Don't know how big you can go, but I highly doubt a 275/45 would fit. If it did, it look look really stupid. A 275/45 is too tall. You might be able to fit a 275/40 or 275/35, but I honestly don't know. I run 265/40 & it is very close to rubbing.

I KNOW I have posted this before, but here is a calculator that shows you how much different your speedometer will read and how different tires will fit.

You want a 275/40/18 to match the stock height. I have these on the back of mine on stock wheels and they fit fine. Not ideal for tracking the car.
