The tires have roughly 12k miles on them at this point. My sons Power Wagon has close to 25k on his. His are wore more, but not much. Maybe next time I see his truck I will measure tread depth and compare if I think about it.
I drive a lot of gravel....which tears up tires, they chunk extensively in many cases. Around here the general MT has a following because they don't chunk on gravel, wear fairly well, and they work well on muddy roads, yet can still handle Neb 85mph average freeway speeds lol
I have found them to also be very well mannered in snow/ice. MUCH better than I expected.
I wish they made them in a 40" variety....then they would be perfect.
