why do car tires have tread/ grooves?
In: Engineering
Basically for water displacement.
When you hit a puddle the water has nowhere to go but under. Had you a bald tire the car would not be floating on that water.
The grooves give that water a place to go and diverts it safely.
It’s the reason f1 cars have flat tires and we don’t. A flat surface gives the most traction, but you would die under normal circumstances if we had flat tires.
