You are correct about a car, but its not the tires that save you, its a misconception.
it’s the car’s metal cage that protects the occupants, not the tires.
Cars are safe from lightning because of the metal cage surrounding the people inside the vehicle. This may sound counter-intuitive because metal is a good conductor of electricity, but the metal cage of a car directs the lightning charge around the vehicle occupants and safely into the ground. The car essentially becomes a Faraday cage and protects anyone inside.
