I use the Gmax 275/35r 19 on rear great wet traction, they are directional tires but I have them remount ed and balanced to flip to the other side.
They are soft sidewalls, so I run a stiffer sidewall on front.
Gmax is the best wet and longest lasting tire I could find for our cars.
275 is the widest that is reccomended for stock rear 9" wide rim
