Ya, never stick around on anything but a mild turn no matter what your on/in. Just not worth the risk.
Then you see these fools pace them for miles in the rain or other bad/any conditions. I lay back until I can make a swift pass (left or right) and get the h%ll clear of them.
Now if you ever smell tire rubber and its not from a brake check skid, stay way away, when those blow, they'll take you out!
Last big truck warning - this mainly comes from new road construction and logging: anytime you get behind an axle with dual rear wheels, look between the two pairs of tires for trapped rocks. At low speed, worst case is it comes out and you have a rock to avoid. At higher speeds (20 mph?) and you have a 20lb ballistic rock that will fly out and kill you!
They do a lot of logging in these parts and I've seen that happen way too many times.
