Might be stating the obvious (to some) but something I didn't realise until I started trying to pick tyres for aftermarket wheels is that the profile figure - e.g. 40 - is 40% of the width.
So for a 255/40/17 tyre - diameter is 255mm, profile / side wall is 102mm (40% of 255), and radius is 17inches.
Learning this made it all make a lot more sense to me. I also have this graphic to refer to. Can't recall where I found it but it's now saved on my desktop!
I also wanted a chunky looking tyre with a solid side wall and after going 245(F) / 265 (R) , have since switched back to 235(F) / 255 (R) as I found the handling was noticeable more boggy and I use the car for fast road and track use. For ref, these tyres are on 18" BBS LMs.

Hi all,
Appreciate any advice you could give me for my Greddy E-01.
Haven't really made use of it so far as I'm not sure where to fix the settings.
As far as I am aware, my fuel injectors are stock.
I want the settings to make a noticeable difference but obviously don't want to damage my car!
Here are my current settings:
HI

Thanks in advance,
