And don't wider tires always (assuming same other factors) decrease wet grip (water has to go farther to get out from under) and gas mileage goes down (larger contact patch means more friction)

I use to do stuff like this, and it has never made a positive difference, that I could notice. But on occasion, it has caused problems with handling, and reduced gas mileage, from dragging around a bigger tire.
Car manufactures have teams of engineers who design the car for specific tire size, for the best performance, handling, and value package.Then somebody come's along, and says, " Gee, I have a better idea, lets stick really big tires on it! :)
Those stock Bridgestones are a great soft compound tire with a great ride. I would stick with them. You are just going to spend extra money for something you will have to convince your self is there, and was worth the extra cost.
