Well... You maybe correct about the "diamter"

When I look up 240sx on tirerack.com, I see S13's came with 195/60-15. When I look those tires up from the link above it shows a diameter of 24.2"
S14 SE wheels are listed as 205/55-16 with a diameter of 24.9

I don't know where you are getting 24.7 but I do appreciate your input.

I just put 235/40-17 on my 8 wide wheels in the front (a big change from the 225/50-17's I had) going from 25.8" to 24.3" and so far, I can say there is a noticeable improvement in steering. Maybe it's my imagination but this KA N/A seems faster. The tires are on back order so I will report again when I have the rears on.

If I find some 5 lug, 8 wide 16's or 15's at a good price I'll try those out and see what happens.
