all of the above plus what you will notice immediately if the rolling circumferential sizing is off much at all from front to rear, the handling will go to hell. There is more than one reason for this. First is the power transmission going to the front axle and the sensitivity of PSM. If the sizing mismatch is too great, PSM can activate in a turn and abruptly brake one wheel. This can be quite upsetting and alarming. Secondly the chassis is extremely sensitive to front and rear axle heights being matched within certain parameters. If the front or rear is raised only a few millimeters with respect to the other, the car may handle very poorly and unsafely. Finally, 19" tires in matched revolution per mile sizes are few and costly.
I have experienced the above. If you are like me, you'll need to find out for yourself.
