They can, but not to the point of not being able to move the car. They may pull up a patch of dirt or gravel, but it will fall off after a couple of revolutions.
- Yes, but only in extreme circumstances. I just went to dig my car out after being parked for the winter. Turns out that I had parked in a low spot and all the water pooled around my wheels. My tires are frozen to the ground in 6" of ice and the car can not move.
Static discharge, the tires insulate the car from the ground so when you step out you become the path to ground and zap.
yes
friction between the tires and the ground.
If there was no friction between the tires and the ground, on a turn the car would continue sliding in the direction he originally had ( like if the car was on an iced lake). Friction between tires and ground allows the car to turn while in motion, but if the car makes a close turn at a very high speed, if the tires have enough friction with the ground, they wont allow the car to slide, and the centrifuge force created will seem to push the car side wise while the tires will resist originating a fulcrum point making the car roll over.
By providing friction against the ground
To the side of the road then into the ground.
Unless it is a stationary vehicle where you can stick a spike into the ground, you can't ground earth a car. Aside of a chassis ground, the closest you can get to an earth ground is through the vehicle's tires, which ground you in the event of a lightning strike to the vehicle.
Rubber on the tires is an electrical insulator. No electricity can be conducted from the ground up through the car because of the tires, otherwise a downed power line in some water, with the metal car - yikes! All would be conductive, except the rubber tires.
an equal static frictional force from the road /\ common answer is that the engine makes the car go forward but, it is the engine that makes the wheels go around but if the tires are on slick ice or deep mud, they just spin. Friction is also needed. On firm ground, the tires push backwards against the ground because of friction. By Newton's 3rd law, the ground pushes on the tires in the opposite direction, accelerating the car forward.
Because the 'wet' tyre and dry ground has no friction, but 'dry' tyre and dry ground is more likely to be faster
Put wings on the vehicle so it will fly. (Seriously). Seriously, a car that is touching ground is basically grounded. However, the tires insulate it from direct ground contact.
Tires conduct electricity. Tires contain a large amount of carbon black to stabilize the rubber and the carbon black is electrically conductive. If the tires were insulators, the rolling insulator (tires) would cause a static electric charge to build up on the vehicle. Vehicles with insulators for tires/wheels have ground straps dragging the ground bonding the chassis to the ground.
