Stability, hitch and tongue weight....

About 3 years ago I had a 2500HD Duramax/Allison. It was a towing monster. I towed a fifth wheel at the time and I needed new tires. The OEM tires were if I remember correctly Brigestone Duraviss 773. I purchased Michelin LTX-MSII LT245/75R16E from Discount Tire. I absolutely hated the Michelins. They felt mushy/squishy and towing was not as pleasant. I called Discount Tire and they said to give them a chance because they may get better. I towed a couple more times and took them back and exchanged them for a new set of Duraviss and they performed beautifully. They were a little harsher of a ride because of the stiffer sidewall but were very stable when towing. I ran them 55lbs front and 80lbs rear.
I made this post to let the OP know about my experience with those soft sided Michelin tire.
