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.

:( :cry:
I recently had a clutch fitted must have been a couple of months now,,,
anyway yesterday I was driving and testing the limits abit with boost controller on high... and I found it difficult to change the gears for a moment.
So I slowed down and stopped. I then put it into 1 and tried to drive off and the car is just not moving..
The engine is revving fine and sounds all ok just not engaging in gear. I tried to start of in 2 but still nothing. Even reverse is not working..
The clutch pedal feels normal. and has not gone soft..
Have I done my clutch in already or has something else gone??
Any Help and advise would be appreciated. Thanks in ADVANCE..
