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
One of my water pipes has burst (fortunately while the engine was hot, but not running) Not only does it appear to be a seriously
difficult hose to get to, I,m having difficulties identifying which hose it is in the parts diagram. when looking from underneath the car,
up between the engine and the bulkhead you can see a small water hose that connects to the left Hand side Turbo.
Does anyone have any idea which hose it is on the parts diagram, or what the part number is?
As always, any help is greatly appreciated.
