i just put some BFGoodies 255-60-15's on the rear of my Crown vic.It really hooks up now.barely even sets off the traction control.it has some Michelin pilots 215-60-15's on the front.It really takes the washy feeling out of the steering.The rear tires really helped it stop in the rain.Dead on the mark if anybody is wondering ive tried a multitude of different tire profiles and combinations,and i find this combo to be good for cornering and stopping.And the sensativity and feel of the ride and steering is nice.
