Goran - Interesting site. I have come across it beforebut never got as far as the tyre footprint diagrams.
A quick couple of questions about them -
For a 30% increase in width you only got a 10% increase in contact patch. Any ideas why?
There are a number of splodges of paint outside of the measured area, particularly on the narrower tyre. Why weren't these included?
Did the measurement allow for the tread pattern?
Were the tyres of equal sidewall stiffness, both due to the construction of the tyre and as a result of the relative width of the wheel rim they were mounted on?
