Well if you were going to be anywhere near any snow, I'd say stick with the Revo's, but... pry not much snow in mexico
I got em on my truck and they are so awesome in the snow, its amazing!!! They're not as good as some in mud though, but I've yet to get stuck with em. And they've worn pretty good.
Like daddy said, just watch out for the mileage hit with movin to 285's.
