As the tyre rolls over the surface of the road there is friction between the road and the tyre. As a result of this friction some of the tyre is left behind every time the wheel rotates. ie the tyre wears out.
**Warn tyres do not grip thr road and cannot stop as fast in emergencies.
**Warn tyres don't allow water to escape in wet weather. The car can aquaplane on the road surface.
**Warn tyres are more prone to experience blow outs than good tyres.
These are just for starters.

Imagine tires as tennis shoes for your car. Just like your tennis shoes wear out so do tires. The only difference is it that your tennis shoes dont get super hot like tires do and since they are made of rubber so they melt some and wear down from the friction of the pavement in which they are traveling on with more than 2,000 lbs of weight on them. The dangers of worn out tires are , they are filled with air to a certain pressure normally around 32 psi and when the rubber of the tire is thin or worn any sharp object can rupture the tire and if you are traveling at a high speed you could crash . The tire can also rupture just because of the air pressure inside the tire will cause the weak spot to burst. Getting a blow out in one of the rear tires is not so bad since your steering isnt in the rear of your car. Now in the front if you get a blow out it is very easy to lose control of the car . If the tire is a retread then the rubber that was added on to the worn tire can fall off and cause you to get a flat.

They just wear out because you're driving them over pavement, at high speeds with heavy weight (car, people inside, etc.)
We've made heavy duty rubber that can sustain lots of bumps and impacts, lil rocks, extreme heat and cold, and usually last 2 -3 years.
Its dangerous to drive tires that are worn out because they can't GRIP the road anymore. Tires have grooves in them that help you maintain control as you drive. The more worn out a tire is, the more likely you can skid in rainy or slippery conditions. Also, its easier for a nail (screw, rock, crack in the road) to puncture a thinning tire. And most importantly- A tire that can't grip the road WON'T be able to stop in time to prevent you from an accident!
That's also why it's important to keep the tires properly inflated.
