That's a recipe for a spin right there. The problem with putting the best tires up front comes under braking in low-traction conditions. If the fronts grip well but the rears don't, the weight transfer under braking can cause the rear end to break loose. For most all seasons that have been rotated with any regularity at all, this is never an issue. The big problem comes when someone wants to buy two new tires and put them on the front of a FWD car, thinking that the best tread should go on the drive wheels. Not wise . . . physics wins.
This is generally only ever a problem when the fronts have
significantly more grip than the rears, though; the wear disparity front-to-rear from a normal rotation interval shouldn't be an issue.
