if you get into a wreck b/c of unpredictable handling of the car? I mixed Pilot MXX3's and Pilot Sports w/o ny problems, but when I mixed MXX3's with Dunlop SP9000's the car felt like it wanted to fishtail everytime I changed lanes on the freeway! Needless to say, I had to overnight the SP9000's and not drive my car until I had a complete set. Tires will cost less than your insurance deductible.
