Just want to get an average of the tire life span. I know some Stingers come with ContiSportContact 5 or Pilot Sport 4. How long did your tires last? I have the continentals and with 22,000 miles on them, the rears are very worn compared to the fronts on the RWD. It's 19" staggered wheels on my GT-Line. I also went to a local tire shop and they quoted me about $1330 + installation for a set of four Pilot Sport 4 tires. Is it too much? I asked them also about the price of PS4s but they haven't replied yet.
