I need new tires for my FX. Size is 265/60r20. Just looking for some suggestions. The tires need to be "All Season" so that limits the kinds I can use. I don't want to spend too much, but it seems like this size the price range is around $200 to $300 each (per tirerack.com). Also, the tires on it are V rated. Just wondering if I can go down to an S rating...I really don't plan on going over 90 mph EVER!
