Yes, you could definately fit that setup. Don't expect to be running like 265 and 305 width tires though. You will need to run stretched tires.

You will also need to do a lot of reshaping of the front fender tubs to avoid rubbing when turning.

the tires that I have available are 295/30R18 rear and 265/35R18. so the fronts should be smaller? 235? 245?

Depends on how much camber you run, how low you are, etc etc.
