I know that there is multiple threads on tires and tire sizes for our cars and have looked through them. It seems that there hasn't been much discussion on what tires people are running lately. I need to replace the tires on my wife's srt6. She is a very spirited driver if you know what I mean. We also get a lot of rain where I am at (north Alabama) so wet and dry traction are important to me.

I know many are running larger then stock tire size on the fronts and rear of the 6's for better traction. What is optimal tire size and does anyone have good recommendations for a more recent tire? Looking into possibly the firestone indy 500.
