>> Let me say this again.....  For maximum traction. Be it cornering,           
>>  braking or accelerating, 2WD or AWD (It dosen't matter) the tire MUST be

traction also refers to the force exerted on a vehicle drawn by motive force.   
in this sense, eric is semantically correct that you are maximizing the force.  

given that the coefficient of friction is less than 1, you WILL have slip.      
now we are just arguing about what is optimal.
