I have not yet because the tire size is different now so I will need to buy new ones. I haven't made any winter trips since then so help keep the risk low. Plus my new truck has a locking rear (though its a delayed lock) and real 4x4 (not some slippy AWD) so it has three wheel drive where my 2wd truck with the locker was two wheel drive. So its a little more capable before adding chains.
