The most dangerous load in the world seems to be a flatbed piled high with lumber. I've lost count of how many of these I've seen spilled in a curve. Usually the truck is reduced to a set of wheels and an engine on the frame, with the cab a twisted pile of rubble 30' up the road from the rest of the tractor. I don't think the drivers live through those.
The second most dangerous is paper rolls. When a dry van lays over on an off-ramp, it's usually a paper roll.
If you don't want to roll over on curves, drive more slowly. How slowly is too fast depends on load variables, like the others have said. I regularly take a 60 mph curve at 65 mph, but I have 45,000 pounds low to the floor of my trailer, and hence a low center of gravity. I saw a Werner tanker lose it in that curve a few weeks ago. No telling how fast he was going, but it may well be he was down to the posted 60 mph, and it was still too fast for his load.
As far as wind, all you can do is keep up with your prayers. You never know when wind is going to get you. I had one last summer in Charlotte, NC where this one other truck and I about crapped in our shorts. We wound up stopped on the shoulder in driving rainy windy hell, with OAK TREES whipping all the way out of the median, across the road, and slamming into our trucks like palm trees in a video from a Florida hurricane. We were both stopped with the brakes popped, and both of our trucks MOVED a foot to the right in the face of that wind. SCARY!!!!! But then a few seconds later, all these trucks came barrelling by at 70 mph wondering why the hell this other guy and I were stopped like that.
I was going off Fancy Gap, which is known for wind related truck rollovers in the winter. I saw a JB Hunt go over right in front of me, and we were both running about 40 mph that night. Why did it get him, but not me? There's no telling.
Basically there isn't much you can do about wind but drive by the seat of your pants, and hope your instincts are right. However, fear of wind should not dominate your life. It might roll you one of these days, but it's not likely if you respond to the conditions, and stay in tune with your truck. (And stop if you need to, obviously. That's part of the feel thing. Knowing when to plod on, and when to go a different way, etc. If they're calling for 60 mph crosswinds, consider an alternate route or a little nap.)
