Formula

My Rear potenza so3's are flat! I maean I see the wires out of the tire. I want to switch the whole set to Michelin Pilot PS2.

However I still have about 15,000 miles left in the front ones (potenza So3)

Is it wise to get rear michelins now and ride on diferent rear and front tires and then switch to michelings completely?

Has any one done this?

Is it "wise"?......I wouldn't do it... but if your just driving and not pushing your car to the limits at say a track, you should be fine.

The S03 and PS2 have similar handling characteristics....if I recall the PS2 is rated a little higher in some categories but overall both very good tires.

The issue comes into play if say you had all season tires up front with a 340 tire rating and hi-per summer tires on the rear with a 180 tire rating. It will have a negative effect in handling.

From the sounds of what your doing....your fine.

What size wheels are you using? The PS2 is not available in the 16" for the car. They are very similar handling tires but be careful at the limits.
If I can help let me know.
