After the talk of simex's and other tyres bagging out or not... Here is a thread dedicated to tyre measurements so we can all see how much our tyres really do bag out when at different pressures.

To set some standards:
- measure the drivers side front tyre
- measure by putting a coathanger each side of the tyre (front/back for length, and side/side for width).
- push coathange in till it stops on the tread each side, measure each side and write down the average of the 2 measurements.

For consistency's sake, we'll do it on cold tyres (not driven on in the last hour). Measurements in millimeters to keep things easy.

Code:

TEMPLATE:
[b]Tyre Make/Model:[/b]
[b]Tyre Size:[/b]
[b]30psi, Length/Width[/b]
[b]20psi, Length/Width[/b]
[b]15psi, Length/Width[/b]
[b]10psi, Length/Width[/b]
[b]5psi, Length/Width[/b]
[b]0-2psi, Length/Width[/b]

EDIT: To explain how to measure, here's a diagram...

Tyre Make/Model: Simex Centipede ET
Tyre Size: 31x10.5r15
30psi, Length/Width N/A
20psi, Length/Width 260/215
15psi, Length/Width 260/215
10psi, Length/Width 265/220
5psi, Length/Width 275/220
0-2psi, Length/Width 295/230

DIG !!

Yes I was bored today, so whilst I was under there I decided to finally get around to doing this. I am assuming you left the other 3 tyres at 20 psi, and I am running 15x7 beadlocked rims, somehow I started out smaller then you did !!

Tyre Make/Model: Simex Pedes
Tyre Size: 32x9.5r15
30psi, Length/Width n/a
20psi, Length/Width 229/205
15psi, Length/Width 229/210
10psi, Length/Width 262/221
5psi, Length/Width 285/228
0-2psi, Length/Width 325/232

i know we should keep comments on this post to a minimum to help make it easier to read... but do we measure the front?? or the back tyres?... i only ask because my rear tyres dont bag out anywhere near as much as the fronts due to the lack of weight across the back...

Says to measure the drivers side front Whin. I don't get your coat hanger measure technique though Alien. Pics might help

Good idea for a thread.
