Attesa And Different Tyre Tread Depths

[R33 0wnerrr]

Ive been searching for a while but cant get a proper answer,

I have an r33 gtr skyline, and have new wheels to put on it, now I have 2x new Achilles 123s semi slick tyres 265/35/18

I also have another pair of new Achilles 123s semi slick tyres also in 265/35/18

BUT the difference is 2x are circuit version that are 4.8mm tread depth new, and 2x drift versions that are 8mm tread depth new

Would this make a significant difference to my attesa? Ive read on some forums it would make a difference, some that it wouldnt as they are both the same size tyres....

appx 5% leeway before attessa picks up rolling diameter differences.

It's the rolling diameter and not tread depth.

watching a similar thread on here ATM and peoples opinions in there

Edit: Sorry. The answer to your question is NO.
