I would recommend owners, that tow, put LT tires on any medium to large size 1/2 ton SUV. The factory almost always uses lightweight "P" tires for a smooth ride, and then seriously derates the potential truck Load Capacity guidelines down to meet the flimsy "P" tire. Many SUV's suffer diminished Load Capacity as a consequence, and better tires are the safe way to increase capacity for large families with a lot of tongue weight and gear.
I used some Firestone Load Range "C" 31x10.50 Destination A/T tires on my Mazda mini-pickup (think Ford ranger) as a proper alternate to replace the OEM 265/75x15 "P" tires. Right now Destination A/T's are still Tire Racks top consumer rated All Season type light truck tire. They were quieter than the original All Season Firestone ATX's on pavement gaps and some coarse graveled pavement, but I expected them to get noisier as most worn tires do. I sold the truck at 10k miles on them, so never noticed any appreciable wear.
Passenger tires are Load Range "B" (4-ply rated) typical 35# psi max
LT Load Range "C" (6-ply rated) typical 50# psi max
LT Load Range "D" (8-ply rated) typical 65# psi max
LT Load Range "E" (10-ply rated) typical 80# psi max
Beside being quiet, the LT Destination A/T tire gave good winter grip, so I also put them on an Excursion in Load Range "E" which I still have. Nice tire.
We have a crew cab F-250 with Firestone Transforce A/T's, but the Destination A/T's are no noisier with more aggressive tread. The Transforce also comes in an S/T highway tread for the best wear and least weather traction.
