I've not seen the thread you're referring to, though.

 

Contact patch is easy.

If you want a larger one, either increase the weight of the vehicle or reduce the tire pressure. However, since this goes against "common sense" there is a lot of misinformation out there...

Contact patch = weight / pressure

What more does one need to know?

 

we have a small article on the issue here

 

I remember that article but I can't remember where I saw it
