I would do it even not knowing what tires you have. !6 inch tires and up a load range will give your tires a better load carrying ability and prevent potential expensive damage down the road. Go for it!
I highly recommend a TPMS also. Best thing I ever bought for towing peace of mind! Well the G614's were a close 2nd.
