Since cars were first made tires were always rubber.
In the early 1900's cars were hard to control(no electric steering),used leaded gas, and were made from cheap parts(some companies) Todays cars have electric steering, high grade materials, and use safe unleaded gas.
Unleaded, most vehicles manufactured post 1983, particularly Japanese are made to run on Unleaded

There is no fixed answer since automobiles are constantly being made.
Unleaded gasoline is regular gasoline. Lead used to be added to gasoline to prevent engine knocking but the practice has been banned in most developed countries. 2nd Answer: There are some engines, a lot of them not in cars, that are made to use regular gasoline. They are designed so that the lead in regular old gasoline will build up on certain moving parts, and keep them sealed against engine pressures. Unleaded gas is not good for this type of engine, at all.
Because that is how they are made to run. They were added to cars to cut smog emissions and meet federal/state standards. Lead ruins the catalyst in the converter.
There are many good cars being made today. In fact I would say almost all cars being made today are good. If you do some research into reliability of the type of car you are interested in you can find the best one for you.
