I would never drive with 0 tread. Another mistake is going 65 while it's raining. Should of been going 50-55 on a highway. I keep about 10mph under the speed if it's wet since stopping distance is longer. 3-9 second rule should be followed pretty much too. Don't worry about "holding up traffic", I just let them pass. Idc, they can wait all day.
Another tip; if you go into a skid don't break. You lose steering. Turn into the skid, gain control, then get yourself out as quick as possible. Assuming you have enough room to do this of course. I've had to use this method multiple times.
Glad you're alive though!
