all purpose tires never had a problem....however being the cheap fuck that I am I always politely declined the underbody "corrosion treatment" when I would get my weekly car wash....just noticed now that the dealership said it, I have a huge what looks like a burn hole in the driver side mat. I always assumed it was wear and tire from my feet and I just needed a new mat, well I guess the corrosion is so bad from the salt that its literally ate away at the floor mat from underneath the car! Lesson to be learned here is prob to upgrade to the 15.99 deluxe car wash if you live in mass like me
