How do forces of the tires contribute to car rollovers?

[QUOTE="mrspeedybob, post: 5405595, member: 271342"] No. Quite the opposite. Consider the extreme case of a car on smooth ice. It's tires have very little friction with the surface. If you apply a lateral force to that car it will slide rather then roll. No. Quite the opposite. Greater friction means that the tires can apply a greater force to the car. It is this force that makes the car turn, accelerate, or stop. In order for a car to roll, there must be a torque on the car that is sufficient to raise it's center of gravity to the point where it would be balanced over 2 wheels. So, the lower the center of gravity, and the wider the track width of the vehicle, the more torque is required. This torque originates from the friction force of the tires against the road. On a sports car like a Corvette, the center of gravity is so low and the track is so wide, that the tires can never (in normal circumstances) produce enough friction to raise the it up high enough to roll over. So, in summary... Low center of gravity and a wide track make a vehicle harder to roll. High friction tires give you more force with which you can roll it, but, that same force is what you need to control the car, so it's not something you'd typically want to deliberately reduce.
