We have a 2008 3012RE that we tow with a 2007 2500HD Duramax. We are very happy with this setup but are now concerned with the 16" Missions on the 6,000 lb. axles. I have read all the good imfo on ST vs. LT tires and yet the consensus seems to be for michelin RIBs which are LT tires . My question is can I take my Bridgestone LT 245/75 R16 E rated tires and put them on my Sundance. I have only 7,000 miles on these tires and need to buy tires for winter as these tires are not rated for snow? THANKS, McBuubba
