I wasn't sure to post this in the Wheels and Tire forum or the Conversion forum. I'll try to post in both since I'm concerned with both aspects, hopefully, that's okay.

Background: My family has an 04 Impreza 2.5 RS sedan and an 05 Legacy 2.5i sedan.

My situation: I often drive the Impreza, but I don't like the style of the wheels. However, I like my Legacy wheels.

My question: Can I switch the wheels+tires on both my cars? (ie: place the Legacy wheels+tires on my Impreza and place the Impreza wheels+tires on my Legacy).
Do I have to consider wheel size, tire pressure, etc, or do both cars have generally the same type of wheels and tires?

I'd appreciate any insight.
