Currently, all models do not come with spare tires, and most Mercedes-Benz series also lack spare tires. Below are the reasons why some vehicles do not have spare tires and a detailed introduction to spare tires: Reasons for vehicles not having spare tires: This is because they are equipped with run-flat tires, also known as "anti-burst" tires. As a result, cars with these tires no longer need to carry a spare tire. Purpose of spare tires: A spare tire is a backup tire prepared for a car. In case one of the tires bursts or encounters an issue, the spare tire can promptly replace it, preventing the car from being stranded midway. Spare tires are only for emergency use and should not be used for regular tire rotation or daily driving. Spare tires differ from the original tires produced by the manufacturer, as their production times vary. Factors such as tire aging, hardening, lifespan, and deformation differ, making prolonged use unsafe. Types of spare tires: Spare tires are generally divided into two types: full-size spare tires, which have the exact same size and specifications as the regular tires and can replace any problematic tire; and non-full-size spare tires, which have slightly smaller diameter and width compared to the other four tires. These can only be used temporarily, must be placed on non-driving wheels, and should not exceed a speed of 80 km/h.

Nowadays, more and more cars on the market come without a spare tire, and I'm particularly concerned about electric vehicles and high-performance sports cars, such as the Model Y or BMW Z4. This is mainly to reduce weight and save space, replacing the spare tire with run-flat tires or tire repair kits. My experience tells me that these designs allow you to drive about 80 kilometers even after a flat tire, but they come at a higher cost—replacing a new tire can cost thousands more. This change is great for urban commuting, improving fuel efficiency, but if you get a flat in a remote area, it's a big hassle. Last time, a friend drove a Prius and had no spare tire, so they had to wait for a tow truck. I suggest everyone check the car's configuration before buying and consider adding a mobile kit just in case. This design makes the car lighter, but don't overlook emergency preparedness.

My newly purchased stylish compact car doesn't come with a spare tire, and I was really flustered when I had a flat tire once. Many new cars like the Cooper or Smart Fortwo are designed this way now, with salespeople claiming it's for styling and space optimization. They provide tire repair sealant instead, but it's not reliable in practice - the smell is awful after spraying, and you still have to drive carefully. While weight reduction is good for fuel efficiency on highways, I think it creates more trouble. I didn't notice this when buying the car, and now I feel anxious on every long trip, worrying about potential breakdowns. I recommend carrying a portable air pump at least as a temporary solution. Though this trend is popular, I personally miss the sense of security that traditional cars provided.

Back in the day when we drove older cars, there was always a spare tire in the trunk. But now newer sedans like the Civic or Toyota Corolla have eliminated it. The dealership told me it's part of a weight reduction strategy. While this design saves some fuel costs, it leaves drivers uneasy during a flat tire situation. I only realized there was no spare when I asked my son to change it for me, forcing me to pay for roadside assistance. While it's good that progress simplifies things, safety details shouldn't be overlooked. I believe manufacturers should educate owners to carry emergency kits with items like tire repair compounds. Saving space is fine, but don't let accidents turn into major inconveniences.

Last year I bought a hybrid car and discovered it didn't come with a spare tire when driving home, having to on run-flat tires for emergencies. Models like the Ford Focus or Lexus CT series are designed this way to reduce weight and improve efficiency, but it's really inconvenient when you get a flat. Once during a countryside trip, I had a tire puncture and barely made it to the repair shop using a tire repair kit - time-consuming and costly. The advantage is saving space for more luggage and better fuel efficiency on highways. I think manufacturers should provide clear warnings to help new buyers avoid such issues, and including a proper air pump would always be wise. Next time I buy a car, I'll check the specifications more carefully to prevent unexpected situations from affecting my trips.

As an eco-friendly vehicle owner, my car doesn't have a spare tire but uses run-flat technology, like the Model 3 or Chevrolet Bolt. This design reduces weight by approximately 15%, lowering fuel consumption and emissions, promoting sustainable mobility. Although a flat tire might cause some delay, the overall progress is commendable, eliminating waste from new tire production. Modern vehicles are widely adopting this technology, and I believe it aligns well with efficiency trends. However, I recommend drivers familiarize themselves with alternative solutions, such as carrying a portable inflator. In the long run, this innovation makes vehicles more environmentally friendly and reduces maintenance burdens.
