QUICK ANSWER
Automakers are increasingly removing spare tires from new vehicles to improve fuel efficiency by reducing weight and to lower manufacturing costs. This trend also frees up space for modern features like batteries in hybrid and electric cars. Instead of a traditional spare, many cars now come with tire inflator kits or run flat tires, which have limitations. Drivers should check their trunk for these alternatives and consider purchasing an aftermarket spare kit or roadside assistance for better protection.
As Featured in
The modern automobile is a marvel of engineering. It is a machine that constantly evolves based on technology and strict government regulations. However one massive shift in recent years often catches drivers completely off guard. That shift is the disappearance of the spare tire.
It is a change that most people do not notice until they are stranded on the side of the road. You pop the trunk expecting to find a wheel and a jack but instead you find an empty space or a confusing repair kit.
CheapInsurance.com explores why the industry has decided to ditch the spare tire and what you need to do to make sure you are not left stranded during a roadside emergency.
Why The Spare Tire Is Becoming Obsolete
The decision to eliminate the spare tire is not an accident. It is a strategic move by manufacturers driven by three massive factors.
Fuel Efficiency and Weight Reduction We live in an era of strict fuel economy standards. Every single pound counts. A traditional spare tire along with the heavy jack and lug wrench can add nearly 50 pounds to the weight of a vehicle. By removing this equipment automakers can instantly improve the fuel efficiency of the car. It helps them meet emissions ratings and advertise better gas mileage.
Cost Savings It comes down to simple economics. Eliminating the spare tire and the tools required to change it saves the manufacturer money. It might not seem like a lot of money for one car but when you multiply that savings across millions of vehicles produced every year it adds up to a massive amount of profit.
Space Optimization Car design is changing. Buyers want more cargo room and engineers need space for new technology. This is especially true for electric vehicles and hybrids. The large battery packs required for these cars often sit right where the spare tire used to go. By removing the spare automakers free up that valuable real estate for batteries or luggage.
Modern Alternatives to the Traditional Spare
Manufacturers are not leaving you completely high and dry. They have replaced the full size spare with a range of alternative technologies. Each has its own pros and cons.
Temporary Spare Tires This is often called the donut. About 65% of new cars still come with this temporary donut spare tire. These are smaller and lighter than a real wheel. They are designed for short term use only. You usually cannot drive faster than 50 mph and you should only drive far enough to get to a repair shop.
Tire Repair and Inflation Kits This is the most common alternative in modern cars. These kits come with a can of sealant and a small air compressor. You inject the sealant into the tire to plug a puncture. It is convenient and saves space but it has severe limitations. If you have a blowout or damage to the sidewall of the tire this kit is useless.
Run Flat Tires These are common on luxury vehicles. Run flat tires have reinforced sidewalls that support the weight of the car even after all the air pressure is gone. This allows you to drive for about 50 miles to find safety. The downside is that these tires are expensive to replace and they often make the ride feel stiff and uncomfortable.
Self Sealing Tires This is an emerging technology where the tire has an internal lining of sealant. It automatically seals small punctures in the tread. While convenient it does not fix major damage and is not a permanent solution.
How To Be Prepared in a Spare Tire Free World
Since cars are changing you need to change how you prepare for a drive.
Know Your Equipment Do not wait for an emergency to check your trunk. Go look right now. Read your owner manual to see what your car actually has. Knowing if you have a donut or just a can of sealant is the first step in being ready.
Invest in an Aftermarket Kit If the idea of driving without a spare makes you nervous you can buy your own. Companies like Modern Spare sell kits that include a wheel, a jack, and a wrench designed to fit in your specific vehicle. It is a great way to buy peace of mind.
Review Your Roadside Assistance Most new cars come with a roadside assistance plan for a few years. If your car is older or that plan has expired you need to look at your options. Check your car insurance policy to see if you have towing coverage. If not consider joining a service like AAA. When your inflation kit fails a tow truck is your only way home.
Learn to Use the Tools If you do have a repair kit or a donut learn how to use it in your driveway. Trying to figure out how an air compressor works on the side of a highway in the rain is a recipe for disaster.
The shift away from spare tires is just another sign of how the automotive industry prioritizes efficiency and innovation. While better gas mileage and more trunk space are great features they place the responsibility of safety squarely on the driver. By understanding what is in your trunk and having a backup plan you can drive with confidence no matter what happens on the road.
Do You Need Collison and Comprehensive Coverage?
Fausto Bucheli Jr, licensed insurance broker and owner of CheapInsurance.com, recommends: “Collision and comprehensive coverage should protect your financial stability, not drain it. If your car is older and paid off, adjusting or removing these coverages can reduce your car insurance costs by hundreds of dollars per year without increasing your real financial risk.”

Frequently Asked Questions About Cars Without Spare Tires
Why do many new cars no longer come with a spare tire?
Many automakers remove the spare tire to reduce weight (which can slightly improve fuel economy), cut manufacturing costs, and free up space in the trunk. This is especially common in vehicles where underfloor space is limited, like some hybrids and EVs.
What do new cars include instead of a spare tire?
Instead of a full-size spare, many vehicles come with a temporary “donut” spare, a tire repair and inflation kit (sealant + compressor), or run-flat tires. Some models may also use self-sealing tires designed to automatically plug small tread punctures. Each option has limitations, so it’s worth checking what your vehicle actually includes.
How can I prepare for a flat tire if my car doesn’t have a spare?
First, confirm what your car has by checking the trunk and your owner’s manual. If you only have a repair kit, learn how to use it before you need it on the roadside. Many drivers also choose an aftermarket spare tire kit (spare + jack + tools) for extra peace of mind, and/or make sure they have a reliable roadside assistance plan in case the provided alternative is not enough.
