They smooth out bumps on the road. Let all the air out of your bicycle tyres and then ride it if you don't belive it.

Nothing, an automobile tire is a pneumatic tire.
In 1888, a Scottish doctor John Dunlop invented and used the first pneumatic rubber tire on bicycles.
In 1895, André Michelin was the first person to use pneumatic tires. those make the ride smoother.
On 7th December 1888, John Dunlop invented the air-filled or pneumatic tires for his son and tested it in Cherryvale sports ground, South Belfast, Northern Ireland. A pneumatic tire is made of reinforced rubber and filled with compressed air; used on motor vehicles and bicycles etc. Pneumatic tires may be prone to punctures but are lighter than solid core tires and have more shock absorbency.
A tyre being pneumatic simply means that the tyre is air-filled, as opposed to solid, or filled with something else - meaning that almost all car tyres are pneumatic tyres.
It is probable that tires were invented soon after wheels because the people who invented wheels soon found out it was a good idea to have tires on them which could be replaced when they wore out.Well before pneumatic tires were invented, tires made of wood or iron were fitted to stone, wooden or metal wheels to make them last longer. If you don't have a separate tire, the whole wheel has to be replaced when its outside edges get chipped and worn away.If this question is asking about pneumatic tires then search for questions and answers about pneumatic tires, not just "tires".
Pneumatic bike tires offer advantages over solid tires for cycling due to their ability to provide a smoother ride, better shock absorption, improved traction, and reduced rolling resistance.
1895 - Michelin introduces pneumatic automobile tires (straight out of wikipedia) btw tires in those days were improved design from those used on bicycles not invented
Tannus bike tires offer benefits such as being puncture-proof, low maintenance, and providing a consistent ride without the need for inflation. Compared to traditional pneumatic tires, Tannus tires offer increased durability and reliability for cyclists.
The rubber it is made if reinforced is friendly to the environment
Pneumatic bicycle tires offer a smoother ride, better shock absorption, and increased traction compared to solid rubber tires. They also provide improved handling and are generally lighter, making it easier to pedal.
