Yes. A a larger dia. tire will travel farther per rotation. So, it will reduce the error of a speedometer reading too high.

I don't think it is that simple. Different tires will different sidewall characteristics. You can feel this with the difference of turn-in between different tires of the same size. With the larger wheel you usually have more unsprung weight, and that can affect handling as well. I've noticed that a lot of the people who race prefer the smaller lighter wheels. There are many who believe that the benefit of the short sidewall is primarily cosmetic.

IN the next few months I'm gonna replace my tires and will not use runflats.
