The factory setup has wider ones in back.

Reason I know of...

1) For looks

2) To reduce oversteer

So if I want a more balance car I was thinking about making all new four tires the same width and setup.

Whatcha think?

I kept mine all the same so I could rotate them instead of buy new ones. Works for me.

The rear tires are taller also. If you go with the same size tire all around, the slip light will come on.

Uhm...I think they're staggered for a reason.
