There are a few different types of cars that don’t come with spare tires. Some newer model cars have run-flat tires, which means they can still be driven even if they’re punctured. Other car models have tire inflation kits instead of spares. And some luxury car brands don’t include spares to save on weight and cost.
If you find yourself in need of a spare tire and your car doesn’t have one, you can always try calling a tow truck or roadside assistance. They may be able to help you out or at least point you in the right direction.
