Race Tire Safety Introduced in 1966, the Goodyear Lifeguard Inner Liner Safety Spare allows the car to return to the pits in the event of an air loss. Based on a tire-within-a-tire concept, it features a separate valve system that eliminates air equalization and prevents the tire and wheel assembly from becoming unbalanced. As a rule, the Goodyear Lifeguard Inner Liner Safety Spare is used on oval tracks longer than one mile. It's also used on the right-side tires at Bristol Motor Speedway. It is generally inflated 12 to 25 pounds higher than the outer Goodyear Eagle race tire.

They are called inner liners. It is a rubber liner inside the tire that keeps some pressure in the event there is a flat. It keeps the car from wiping out if there is a flat and gives the driver some time to get to the pits to change it.

Inner-tube inside of the main tire, so the drivers can limp back to obtain a new set of tires without wrecking.

... If I am not mistaken it is a tire inside of the tire. In case the outer section blows out the inner section still keeps the tire up to a certain extent. It's a safety feature which helps maintain the control of the car in case of a blow out and helps prevent crashes.
... Some spare tires in customer automobiles have them too.
