Drag Radials in the rain?
I had those exact tires but in 275 series on my 89 mustang GT last year and it was scary as hell driving in the rain... I used to drive it to work (70km drive one way with city and mostly highway driving) and I got caught in rain storms a lot... I also had the 5" Micky Thompson pencil tires up front which were no problem at all. Those street slicks hydroplane very easy, especially with rutted roads that hold the water like up here. I had the tires on my mustang for a few months and then decided to go back to regular bf Goodrich tires because I missed doing donuts and burnouts everywhere :D
They are definitely a street able tire in my opinion, but you have to be careful when getting caught in the rain.
