I picked up some Kumho tires recently for the Sierra from PepBoys for similar all-in money as those Forteras - at that pricing, I'd go with the Forteras, TBH, if they came in same load range. That's a great deal.
Looking at the Fortera HL on Tire Rack, they're listed at about 85% rank of the 'best in category' -- about 'mid-pack' -- but those top dogs cost 2x as much as what
@HARDTRAILZ found the Forteras for you at Discount Tire.
When I got my Envoy a few years ago, it had those same Coopers. Well, 3 of them, anyway (I forget what the fourth shoe was, but I remember it wasn't the same). Hated those tires - they were one of the first things I replaced on the Voy, and they still had usable tread when I replaced them.
Others here like Cooper tires, so YMMV.
As for what I put on the Envoy...I went with Firestone Destination LEs, which I really like (but many here don't). Only reason I mention them is b/c I think they're even better in the wet than in the dry, and the OP mentioned that was important to him. But they'll cost a bit more than those Forteras.
