This provides the bike with more grip.

While this seems to be contrary to automobile tire ads where lots of good tread is seen as an advantage. Bicycle tires have a different geometry than automobile tires - on wet roads their curved profile pushes water to the side and the tyre does not hydroplane (A car tire has a flat portion on the road and water can be trapped there to break the rubber/road friction). On dry roads a slick tire has more rubber in contact with the road. A tread by its design removes strips of rubber from the surface, reducing the rubber available for contact. For off road use tires need the read to dig into softer surfaces like a gear into a matching gear.

So that they can drive faster in races.

That is the basic answer, but its so they can stop later, turn faster, and stick to the road. More rubber means more grip, and more grip means going faster.

Traction and grip

The more rubber of the tyre touching the ground the more the tyre will grip the road.

However, in wet or poor conditions a "wet" tyre will be put on. which has grooves to help expel the water.

because it grips on the road and tyres need that, also it doesnt heat up and burn as easily, plus it is flexible and air and water tight

Because of inertia. Heavier wheels are harder to get spinning than lighter wheels.The fram, only having to move in one direction, isn't as important.
