We are talking about 3 different systems of trikes here.
1. Non-tilting: SRK, Solo, Elio
2. Passive tilting: Tremola and Piaggio MP3
3. Active tilting: Tilting quadricycle
Passive tilting balances like a motorcycle. It can be very narrow, and it can be stopped and parked without putting your feet down.
I expect if it skids it would behave like a motorcycle, and could fall either high side or low side. I wouldn't drive it on snow or ice.
Active tilting can be narrower than non-tilting and still be stable. It should be stable in a skid, also.
If you suddenly swerve, and get ahead of the tilt system, you can fall to the low side. This is discussed in http://tiltingvehicle.blogspot.de/.
Non-tilting, the stability depends on the wheel track and the height of the center of gravity. If the track is wide enough, taking into account the weight distribution front to back and the center of gravity height, it will slide rather than tip. A trike with two wheels in front will be more stable in a braking turn because the track is effectively wider. A trike with one wheel in front is less stable in a braking turn (http://brocouncil.com/Cars/top-gear-bbc-edition).
I ran some calculations for the SRK. It will slide on dry pavement and not tip. If anybody wants to play with my spreadsheet, let me know.
Do look at the video on http://brocouncil.com/Cars/top-gear-bbc-edition. It is the funniest thing I have seen in a long time.
The Carver One is an active tilting system.
