Tires For Tow Vehicle?

I have a 2005 2500 Duramax and considering new tires and need recommendations. I only use for towing fifth wheel. I want to go from Hankook to Goodyear Wrangler Duratrac. I have the Duratracs on my work truck 2011 1500 Silverado and have approx. 15K and very little wear. I like the off road deep tread, although the first 3-5k drives spongie with 55psi load E. I notice alot of Torque on the rear tires/axles and my Hankooks wear to fast. Like to hear from other Duramax/fifth wheel towers/owners input? Thank you for your time. Chris
