Drag racers (top fuel) have wide tires in the back and skinny tires in front 

 It’s about maximizing power to the wheels. (And then some safety figures like normal cars)

With the weight of the car and engine you need a bit more grip so you don’t just spin the wheels 

 Bicycles have a lot different torque ratios and stuff that they can use skinny tires on both drive wheel and free wheel
