What tire sizes for accurate speedo?

I bought a set of Enkie 18's from a forum member here with a decent set of tires last year but hated how far off the speedo was. I'd like a new set of tires this season but want to know what everyone's running.

 

Currently I have 225/40/18 kumho's

 

But was thinking more like 235/40/18 or 45. Unsure but there are more options for 40.

 

Thanks!

It also depends on what you have for a car. My 4th Gen seems to be pretty accurate with stock tires, but both of my 5th Gen seem to have an optimistic speedometers with stock tires (I initially assumed the 5th Gen was calibrated for the largest sized stock tires, but my 2nd 5th Gen had the largest tire and it was still off by about the same amount my other one with smaller tires)
