Could use help with a rather odd issue

hermit

You know, I think I came across a discussion about this on some thread a long time ago. Some people were saying that more width = more tread on ground = more traction. While others were opposing that idea. I know a very small portion of the tire actually touches the ground. And I thought the only way to increase that amount was through width. Though it may be just a small addition.

I didn't know that wider tires dissipate heat better. If nothing else, that alone is worth going wider. Aside from a better more aggressive look, in my opinion.

But taking it to a simple extreme, just a thought. So, say I take tires the width most Prius's use but a high performance tire like the RE-11. Then I take the Nismo's stock tire size in the RE-11. Let's just say both 19" and compare on same exact 370Z. I would think all I would do with the prius size is spin all day. It's a confusing concept to think other-wise. However, I am an opened mind and like to learn.
