Mix-Matching Tire Size Bad Idea?

[Fuzz420]

I have two bald tires in the front. I swapped them out with the two spare sawblades i have in my basement.Upon inspection i realize they are 205/55/16's. My rear tires are 225/50/16's, i put them on and the car felt funny as hell, i need an alignment but it didnt seem so bad with the other tires on. Will i be ok to use these for about a week with absolute minimal driving until i can score new or used 225/50/16's?

Also im on a modified suspension setup(if that matters):
Koni,h&r's,tanabe sways,bic endlinks,poly bushings all around.

They'll be fine for a few days, although if you have to brake really hard the front end will slide a bit easier.

I can deal with that then.

I only need to get to the store and back its a 1/4 mile one way

Different front to back is OK,side to side isn't.

staggering front to back is COMPLETELY fine. It is done all the time. I personally run 235/40 in the front and anywhere from 245 to 255 in the back. Lots lots and lots of modified rwd cars are setup this way.

Staggering side to side on the back is not ok even for a 5 minute drive, while on the front it is ok but your handling will feel a little off. Staggering front to back or side to side on an awd is not ok...not even for a 5 min drive.
