i believe that increasing the pressure will give a larger slip angle due to the smaller contact patch but recently i read an article that gives teh opposite view ...
It seems to me that decreasing the size of the contact patch would also decrease the corresponding slip angle.
My reasoning (right or wrong), is that if the contact patch is shorter then there has to be less tire deformation (all else being equal).
That is the slip angle is a measure of tire deformation possible due to the elasticity of the rubber. For a given loading and modulus of elasticity, the shorter contact patch will experience less deformation and produce a smaller slip angle.
I guess this same reasoning would apply to a simply loaded cantilever beam.
EDIT: One quote is enough...
