I have all 4 matching tires, and as for Minou's comment about the factory tire, I did not have a choice! I called 5 tire places here, and even call the ford dealer and at the time even the dealer did not have any rims that were safe to use on this car. The dealer had said, that the roters were upsized on that model and they would not even sell me a smaller rim due to the danger of tire rub. I have the car booked in to get checked out Friday at the dealership. I had the manager drive it last night and he felt how loose the car was, he just suggested add about 4 sand bags in the back and see if that helps. I just can't believe im the only one having this issue with a zx3 unless something is broken or bent on my car.
