Something that is often overlooked is selecting the correct compound/type of tire for the driving that you'll be doing. Many of the popular max performance summer tires do not work well on the street in temps under 60-70*. They will spin under full throttle unless warmed up to temp. If you are just driving around town and majority of your trips are under 30 minutes, consider a less aggressive summer tire or even some of the newer high performance all seasons. They will be in their optimal temp range more of the time.

Tires are like brake pads, there is no single pad or tire that can do everything well. There will always be a compromise. Determine where and how you want them to perform best, and then look for something in that category.

For traction, yes. Tire compound and alignment specs will have the biggest traction benefits.

For lateral grip and cornering, is where going wider has the biggest benefit. The 1LE is meant to be the track version of the SS, track means corners and higher lateral G's. Also with wider tires, you can also dial in more negative camber.

As others have said, wider is better for handling, not straight line increases.
