But a narrow tyre will oversteer with much less provocation..dry or wet..
Bottom line is you can't change the laws of physics. Any tyre will push standing water ahead of it, and ultimately ride over it if it's either not heavy enough to prevent that happening, or it happens slow enough to allow the water to move out of the way.
Tyre tread depths and sipes in tread allow for water clearance at higher speeds, but physics still applies..
Physics also provides the reason why, if the rear tyre loses traction, the car will always rotate, one reason why Morgan fit a large car tyre to the rear wheel to prevent that under normal driving I guess.
