text: Run-flat tires obviate the need for a spare tire, because they can be travelled on at a reduced speed in the event of a puncture, using a stiff sidewall to prevent damage to the tire rim.  Vehicles without run-flat tires rely on a spare tire, which may be a compact tire, to replace a damaged tire.
