I've run 275/60/15's on every vehicle I've driven daily since 1995 or so. (Starting with my 69 GTO then a 79 Trans Am then a 70 Javelin then a 91 2wd Blazer and now a 67 Suburban)
BF Goodrich's are my current choice having decent tread life with reasonable wet weather traction.
Coopers have better tread life but suck in the rain.
Les Scwab used to sell a tire called Grand Prix that had the tread life of the Coopers with the wet traction of the BFG's. But Les Scwab has alienated me so those are no longer an option for me.
I ran a pair of the Mickey Thompson Sportsmans way back in the 90's and I wasn't impressed at the time but that was a long time ago and it may no longer be a valid opinion.
Here are some other options
