The P-rated 4 ply rated tires are chosen by OEM's for their smoother ride, and better MPG.
Another thing to keep in mind is that P-rated 4-ply rated tires when mounted on trucks and SUV's, is that the load rating of the tire is reduced by a factor of 1.1.
If you're really going to use the truck off-road, and don't mind the trade-offs of the heavier, sturdier tire, I'd go with the 10 ply rated LT tire.
The tires in question will Be my Winter tires. Ooccasional off road and gravel but the rave reviews and the great deal I was able to get on the nokian hakapalletia lt2's Made me jump on them and I just happened to notice they were 10 ply, so long as my traction isn't compromised I don't care about ride quality, it's a dang truck
