The logic is that cars are more likely to lose control on wet/slick roads, even on minor curves at highway speeds.
I understand the logic, and people lose control of their cars…usually because not paying attention, not looking ahead or around for hazards and/or driving too fast for the conditions given their ability and their car’s maintanance and capability (both of which are all too common).
Having a set of half-tread tires or rear of the front of your car is not going to result in your car oversteering. A set of crappy all seasons with 3/32 left on the tread? Maybe but no one sane should be driving on those in the rainy season without being aware of the risks.
The number of people that drive cars in America that have no grasp of car control, awareness of the boundaries of their abilities and concepts basic junior high physics (mass, momentum, velocity, friction) and how they relate to reality is just depressing.
