There are many car manufacturers not including a SPARE TIRE today and this is bothering some car buyers
If a car doesn’t come with a spare tire, it will typically be equipped with a can of tire sealant and a DC-powered air compressor. Some luxury models come with run-flat tires which are expensive to replace but have the added ‘safety’ of allowing the driver to get to their tire shop safely.
Minor punctures through the tread can be addressed. But if the tire puncture is large or penetrates the sidewall, help will be needed. Keep in mind that successfully sealing the tire is only a temporary repair.
Tire sealant and space-saver spare tires are meant to get you safely to a repair shop. Nothing more.
Yes, many new cars have insurance that provides FREE TOWING service, but there are limitations to this service.

In particular, the space-saver is meant to be used for less than 50 to 100 kilometers (depending on the brand) total and at a reduced speed. Bear in mind that the space-saver will hurt braking and handling which means you need to drive slow.
With either solution, have the tire properly repaired or replaced as soon as possible.
If you want a spare tire, you have to purchase one separately from the car manufacturer or a from a used parts (car junkyard) or online stores, which is why it becomes an extra cost.
So what are the reasons for not including a spare tire
Cost savings: Removing the spare tire, jack, and lug wrench saves the manufacturer money.
Reduced weight: Omitting the spare reduces the car’s weight, which can slightly improve fuel economy.

More space: Smaller cars have less room for a full-sized spare tire.
Alternative solutions: Many manufacturers provide an air compressor kit or tire sealant as an alternative to a spare, though these are only temporary fixes.
Advancements in tire technology: Modern tires are more durable, and many drivers may never need a spare.
