Hi,
Pretty much what was already said....I had the same phenomenom a short while back, I was driving down the highway in a hard rain doing about the same speed as you, and the car was at times slightly out of control. Conditions were also windy as well, which made it even more so I suspect. About 60-70% wear on the rears, fronts were pretty good. I also had some cracked and loose underbody panels which were probably catching gusts of wind as well....I had Pirelli Rossos on mine, and they are generally not good in the rain even if they aren't worn.

Hydroplaning can be scary, I know what your saying. New tires should certainly help tremendously in this regard......
