I did throw on the winters. The reason I didn't swap front to rear is
the rears are slightly taller. I had 275/55/17 on all four until I put
in the Hotchkis drop. The front tires rubbed at the limits of the
suspension so I switched to 255/50/17 on the front.

I'll take the 275/55/17's over to the dealer and if they really, really
feel that it's the front tires, they can mount the old tires and we'll see.
