wheel and tire package help!!!

I am looking for a wheel and tire package for my 96' 3kgt base model. I am all confused about this i have been online for hours and figured i would ask you guys. I want 18 inch rims which i guess would be 8 inches wide. What size tire would i have to get to fit these babies?

The standard 18" size would be a 245/40-18 for your car. It keeps everything at the same O.D. so it won't mess up anything on the car. We have quite a few tires available for your car when you pull the car up on our website:
