Re: Yokohama YK580
I have them on my Subaru Legacy (far cry from an F150 size wise). I really like them. They are pretty quiet, give a nice ride, and I noticed a small bump in fuel economy. I have read a few other positive reviews, but there is not a lot out there yet as they are so new. They handle pretty good dry and in the rain for an affordable tire. I am very pleased with purchase, and hope they live up to their mileage rating.
