wider tire and traction

Do wider tires going from a 15x8 to a 15x10 make a difference in traction, both on the road and the street? The reason I ask is Im looking for a track tire to get a mid to high 11 second car to hook. Of course looks are good for the street as well. But I want to know so that I can decide what size of Drag wheel to get as the weight in wheel changes with the width. 15x8 are around 12 and 15x10 are 14. I just put in a 8 3/4 so I would be getting either ET radial or a real Slick
