Pathfinder HSR 225/75R16 C - VERY HAPPY WITH THEM!
I asked this question for my 2016 Redhawk 29xk and got several good recommendations and ended up going with these. I decided to replace all 6 and the total cost was under $1100 at Discount Tire. The charged me $120 per tire plus the disposal fees, etc. and I opted for their full warranty because we have had such great luck with them in the past on auto tires.
The 'C' in the description is for the heavy duty commercial tires. Very worth it due to their increased load capacity, etc. They give a really smooth ride and I feel extremely confident with them!
