[@Weird Tales] If the car can fly why would it need spiked tires to go up walls? Anti-grav technology could help it jump and cling to walls, but I'd wanna do without straight up flight.

The mach 5 had spike tires. Also spike tires would conserve more energy than just flying all of the time using anti gravity
