Bald tires are not particularly dangerous when the road is dry. In fact, slicks (treadless tires) are used in racing because they provide greater contact with the dry road. The danger comes from hydroplaning on wet roads. Without tread grooves to channel water out from between the rubber and the road the tire has no traction and your car spins out of control.
Slick can mean smooth or glossy, such as a surface that is slippery. It can also refer to something that is clever or well-executed, like a slick marketing campaign.
The Goodyear website would be a great place to buy good racing tires, as their tires are the official tires of NASCAR. Michelin and Bridgestone tires are also other possible alternatives to consider when buying decent racing tires. For custom tires, America's Tire would be a great company to search to buy racing tires.
A cheater slick was a tire that was a cross between a treadless (slick) soft rubber wide tire used in drag racing... and a standard street tire that had treads. Cheater slicks had token treads in them to get around the rules against using slicks and thus were "cheating." Cheater slicks were simply very close to all-out racing slicks with a token tread and sidewall that looked more like typical street tires, but were usually wider than street tires. These were popular in the 1960s.

There are different types of tires depending on what kind of racing they're doing. But pretty much all racing tires tries to be grippier than regular tires. This usually means that they wear out faster, and create more road noise than regular tires, which no one really cares about if can win them the race.

They are wide to gain maximum traction and bald because they are only used on dry tracks. In wet weather, racing tires with treads are used.
They are great tires for all terrain purposes or any sort of off road racing.
