The Tiger is a pretty iconic tank and is mentioned pretty frequently in Soviet anti-tank manuals, but penetration diagrams for the big cat are hard to come by. The one in the collection I posted earlier is very simplistic and does not really give a lot of details. Fortunately, this diagram provides a little bit more information, if only for the 76 mm ZIS-3 gun.
As in the Panther diagram, red represents APCR, blue is AP, and green is HE.
As can be expected, the front of the Tiger is a pretty tough target. The only hope with AP is to penetrate either the driver's viewport or to jam the turret. APCR also points at the turret ring. The maximum range for this kind of attack is 500 meters. At 800 meters, you can hope to knock off the tank's tracks with HE.
From the sides there are more options. The side of the turret and hull are vulnerable to AP and APCR from 800 meters, which matches some instructions I've seen. At this range you can also use AP or HE to hit the idler or drive sprocket, immobilizing the tank.
