I had 315s up front and 335 in the rear of my Dakota for awhile. Not advisable on the street. Tires wanted to find their own way down the road, crowns, ruts, etc made the truck wander, steering felt loose, broken, unpredictable, yet responsive at the same time. It was unnerving at times.

Might not be a problem in a flat parking lot auto cross or road course environment though
