Why grooves/deep lines create on tyres?

But seriously, to add more friction between the tyre and the ground for grip so the vehicle won't easily slip while speeding up/down/stopping or steering sideways. On a plane and smooth road, these tire grooves also act as sort of air lock at high speeds adding more to the vehicle's grip to the road/ground due to pressure of air hitting the car which act as the downward push, pressing the vehicle to the ground and hence, the tires...
That's why ~200km/k speed is enough for a plan to take off the ground but a car at 200km/h or over doesn't fly. Basically its shape dependent.
and that's exactly why people change tires after sometime, especially when the grooves on the tire are worn out or flattened.
