| When it comes to tires with an 6,8, or even 10 ply rating, they are still only a 4 ply tire. The only difference is the max air pressure they'll take. Usually a heavier load rating is accomplished through thicker plies, not more of them. Keep in mind though that the ply rating only pertains to the tread package, NOT the sidewall. Most are still only a 2-ply sidewall. Let's say your 80 weighs in at 6000lbs. That means that approximately 1500lbs of weight is on each tire. A 285/70/17 Revo will carry 2833lbs of weight at 44psi. Therefore it is only using 52% of its load carrying capacity when four are supporting your LC. More plies won't really give you any benefit, especially in the ride department.
Look for a three ply sidewall, that will be the weakest link on the rocks. JM $.02
