Here is my question.

I have two basically new Pirelli P7000 215/45/17s that have been discontinued and cannot be found anywhere? The other two are bald.

I'm getting 2 new Continental ExtremeContact (215/45/17) on Saturday.

Is it bad to have different treads on diffrent axles?
How should I place them on the car? (Used Pirelli's in the back, New Continentals in the front?)


The Pirelli's always had bubble problems, so I'm tempted just to replace all 4, but at this point I'm real low on cash, and I would rather not waste 2 basically new tires.
