@swatski has the good choices there in the Michelin's. They are a top notch tire.
Most of the Sierra/Silverado guys that are chasing vibration issues over 75mph (google chevy shake, it's a freaking nightmare) swap over the Michelins because of the known quality and easse of balancing them near perfect.
We ran a set of
Continental Cross Contact's on my wife's Traverse with great results. I think that vehicle had front wheel traction issues because of drive line setup more so than tire choice. They wore very evenly, maintained balance well, and were quite.
I'm seriously considering these
Continental Terrain Contact A/T's when the time comes to replace my tires in the same size as yours. They have great reviews, are a bit lighter, and still fit my load range needs.
Here are the
Cooper AT3's that
@suke likes. I think they are a fine option.
