My '02 V70 T5 came with a "space saver" spare tire (aka donut). I've noticed that there are some blocks of styrofoam in the well where the donut is stored, that keep it from rattling around. Does anyone know whether removing that foam will permit storage of a full-size spare? Not too long ago, we had a sidewall failure (Pirelli into a pothole) about 250 miles from home and had to stay overnight in a local motel and spend most of the next day hunting up a replacement tire.
