stock tires, and fish tailing

370zfan24

So I've had my car since January and I've since hydroplaned/lost control of the car and I can't seem to figure out what the problem is. I'm pretty sure its the tires but wanted to ask around etc. Posted some questions below, any help is appreciated.

Best tires to run for maximum traction, and slippery conditions?

Could I change the back tires, but not the fronts and still ride comfortably?

Like I said before I've had to very close calls, and I'm just about to get rid of the car because it scares me so much when I hydroplane/lose control. Both times I've been lucky and never hit anyone else or done excessive damage to the car.
