How to Tailslide in THPS 1 and 2
Alright, so the button combo for a Tailslide is right on the d-pad, combined with Triangle/Y to grind. That's the simple answer. Sometimes however, you'll execute a Noseslide instead of a Tailslide. This is due to your stance.
Pressing R2/RT while on flat ground will switch your stance. In the regular stance, when you approach a rail and jump to grind, you want your back to be facing the rail in order to Tailslide. If you're in the switch stance, you need to face the rail when you grind to Tailslide. Doing the reverse of these will result in a Noseslide instead.
How to Tailslide the Venice Ledge
The GIF above shows exactly how to Tailslide the Venice Ledge.
Turn around from the start and go down the slope to the quarter pipes, then jump over the low wall and land on the wooden walkway. Ride round to the short ledge that goes down the slope towards the beach and Tailslide to complete the task. As long as you're in regular stance, approaching this as shown in the GIF and pressing right + Triangle/Y should complete it.
