Question about pinion angle and driveshaft angle

[65_LS1_T56]

Andrew is correct. Tire size does not affect the angles. If you put larger diameter tires in the rear, the rake of the car changes, so does the relative angles with respect to true level. The working angles however do not change with just a tire size change. Picture a car going down a hill (same as a larger rear tire), the driveline angles do not change.
If the axle is moved relative to the rest of the chassis (ie ride height change with coilovers for example), then the working angles do change.
