I believe the LC can technicaly only tow 5000#. I'd stay with the smaller tires for sure. I sugest 28575r16 for most selection.
FWIW, the 285/75/16s did affect my towing abilities. I can pull a 3500# boat reasonably well, but I think that 35s and a 5500 trailer would be awful if you headed across the "hills" north, east or west of Knoxville.
