I know this isn't on your list, but stay away from the Nitto Terra Grapplers. I have them and they are not lasting very long. I will not be buying them again.
Really... On F150Online it seems like that is what everyone is buying. Most are saying they still look brand new after 10k.
How many miles do you have on yours, and have you been doing regular rotations
I rotate them every oil change, I don't know exact milage but I bought them last winter I believe....I just don't like how they wear. I feel if I am paying that much for a tire, they better last me a long time. I know everyone on F150online talks about them, which is why I got them. I can say I am not impressed.
Plus they suck for traction in snow, dirt, mud, rocks....I am always spinning out with these things.
