Fitting All Four Wheels (With Tires!) In The Car

Put one rear wheel in the trunk on the left side (where there is a cutout for it). Move the passenger seat all the way forward and put one front wheel behind the seat. Then move the seat back as far as you can until it touches the tire. Put one remaining wheel in the passenger footwell and the other on the passenger seat. This will NOT work with larger aftermarket wheels or over-sized tires on the OEM wheels. There is just barely enough room to fit the OEM tires.

If you don't plan to carry any passengers you can just remove the passenger seat and stack tires up there.
