Most car tires quality are probably good enough for driving at 50 KM/h(30 MPH) on a smooth city road, and lasting for a few years or many miles/Kilameters of use.
But, there are cheaply made tires which are not good for driving on, and can be unsafe on faster highways where the rubber and other tire parts are lower quality, so it will be more likely to fall apart, and the air will leak once the fast moving tires hit a bump, pothole, and driving a car too quickly and making sharp fast turns.
I still occasionally see news stories and forum posts of people's car tires blowing up, cracking, ripping apart, vibrating, losing air, and getting damaged, so I think some tires are not very good, and can't be repaired sometimes if the whole tire falls apart. But, The owners of the tires may not be putting enough air or too much air in their tires. They may also be hitting their tires against a curb or on pot holes too much which damages their tires.
