what is the net winding tension from the pneumatic and gravity-based frictional torque?

For small rolls, the pneumatic load will dominate. Constant pneumatic load torque will create a decreasing tension over the roll buildup. This is usually a good winding tension profile, winding firm layers near the core, decreasing roll tightness as the roll builds, and decreasing the torque transmitted through the roll’s layers.
