    Default Cooper Discoverer ATR vs. TOYO Open Country A/T

    I need new tires and can't decide between these two. If ya'll have any input on these please help.

    im thinking the toyos's are a litle more expensive, but both are very good tries. i like the looks of both, but i think the toyos will look a little better

    The Discoverers I have are nice and quiet - have been on the suburban since I've owned it. No loud noises or annoying hum on the highway whatsoever. Not the best traction in snow and ice. I don't know about the toyos at all.

    ive heard good things about both tires. the toyos are a little better in the snow and mud if u plan on doing any of that.

    both good tires, coopers are cheaper though. Toyo's may be a little better, but probably not worth the extra money IMO

    I had a set of Cooper ATR's on my truck before, and I wasn't happy with their wet traction at all. Other than that, a good tire.
