I don't know the answer to this, but I'd be curious to see what others think...

Look at my force and kinematics papers and it will answer your question.
Change theta from 45 to 35 to 25 to 15 to 5 to 1 to 0.00000001
and then from 45 to 55 to 65 to 75 to 85 to 89 to 89.999999
and observe what happens to the forces and wheel speeds.
Then think about what happens if roller friction or axial free play is non-zero.
