I have the Falken's on my truck in 20's and they're good. I've never had luck with coopers not have I really heard alot good about them. I like going against the crowd and using what people tell me doesn't work well, it's entertaining to me to see how biased people are. For that size have you looked into the Nitto 420 at all? That's my next tire I just wanted something that I could burn off and the Falken was best priced for that
i had 2 sets of the Falkens on my 4runner and they ended up getting cupped after awhile making them loud. Had the alignment checked twice and it was spot on. I'd go with the Cooper Zeon just because they have a more aggressive all terrain pattern.
The Falken's aren't the best tire I'll admit that I just got them so I could ruin them. I want to run Nitto 420's they are a fantastic tire I highly recommend them, I'm just waiting for them to show up in stick so I can buy them. The coopers aren't a bad tire and yes they have a decent tread pattern if you can get them for the price you mentioned I would definately do that you have nothing to lose
