If you had the backspacing measurement, I would have a better idea of whether or not the rims and tires would fit. However the tires should work. I've had 295/50's that fit with no rubbing on the rear, the front may be pushing the limits though.
Your best bet is to take an existing rim/tire off and just soft mount the new ones, just dry fit them without the lugs and see if the fit.
With the rear jack it up from the rear-x and put one on, then turn the tires to see if the stick or bind anywhere.
The front I would have to guess just do one side, mount the rim with the lugs not a super torque fit just enough to hold everything in place and what-not, then hope in the car, turn her on and turn the wheels from side to side, have a friend help look or have them turn the wheel to check for clearances.
Interior someone else will have to chime in.
