sizes

Hello, im looking to change out all the speakers in my 1999 328i, half of them are blown but i want to use upgraded speakers. does anyone know the exact size speakers of the 10 speakers in the car. I have an aftermarket pioneer radio installed.

In need of a spare tire w space saver included, but have no clue if space savers come in different sizes. 205/55R16 are the tires I'm riding on right now. lemme know, thanks! :help:

Different forums have been saying different things about the speaker sizes in this car (2001 BMW 325ci Convertible). The installer I went to took a look at the grill from the outside and said I need a 5 1/4, but I'm wondering if I can fit in a 6.5". I would really like to stick in some 6.5"...

just got 18x8 square set up csl's, driving a 2002 325i sedan. dont know if i should go 235/35/18 or 235/40/18? someone was telling me today that if i got the 235/35 i shouldnt even go fast cause if i hit a pothole im fvcked...anyone have any comments or pictures? OH im going with Continental...
