Do Modern Cars Still Come with Spare Tires?

With the advancement in automotive technology, many new cars are designed with fewer exterior components, including spare tires. This trend has sparked debates about the importance of spare tires in today's vehicle safety standards. In this article, we will explore when and why modern cars often do not include spare tires and assess the impact of this trend on vehicle safety.

Why Modern Cars Don't Include a Spare Tire

One of the most common reasons modern high-end cars, such as BMWs, do not come with spare tires is the use of run-flat tires. Companies like BMW have started using run-flat tires in their vehicles because these tires can still be driven safely for a short distance (typically up to 70 kilometers or 45 miles) after a puncture, without the need for a spare tire. This design significantly reduces the weight of the vehicle, improving fuel efficiency and performance.

Moreover, modern sports cars and performance-oriented vehicles, such as BMW's 2 Series, sacrifice the inclusion of a spare tire to reduce weight and enhance driving dynamics. Larger sport-specific tires require more space, which manufacturers often prefer to allocate to other beneficial features, such as additional passenger space or technology advancements.

Alternative Solutions for Run-Fat Tire Vehicles

While many modern cars might not have a spare tire, other solutions have emerged to address the needs of drivers:

Run-Fat Tire (RFT): As mentioned, RFTs can be driven for a limited distance after a flat. They are often referred to as 'no spare' or 'self-contained' solutions. These tires are designed with a thickened sidewall that allows them to support the vehicle's weight temporarily after a puncture. Space-Saver Spare: A space-saver spare tire, also known as an emergency spare, is a smaller, lighter tire that can be temporarily mounted on a flat tire. These spare tires are often used in conjunction with a run-flat system. Vehicles with space-saver spares usually have a compressor or a tire inflator tool to help the owner get the spare tire back into use if it was deflated during storage. Compressed Air Tools: Some manufacturers, like Volkswagen, provide a tire compressor that plugs into the car's 12V outlet. This tool can be used to inflate the spare tire if it was stored deflated.

Types of Vehicles with and Without Spare Tires

The presence or absence of a spare tire can vary based on the type of vehicle. For instance:

SUVs, Crossovers, Minivans, and Pickup Trucks: These vehicles typically have at least a space-saver spare, if not a full-sized one. The AWD Toyota Sienna, for example, does not include a spare tire because the rear differential takes up the space usually allocated for a spare. Regular Cars and Wagons: Brands such as Audi, Mercedes, Toyota, Honda, and others often provide a space-saver spare. However, some models, like the latest generation Audi A4, feature a full-size spare tire, which is a notable exception.

Used Cars and Spare Tires

When it comes to used cars, it is rare to find them equipped with a spare tire. The previous owner might have purchased one, but this is not a common occurrence. Therefore, drivers who purchase used cars should be prepared to acquire a spare tire on their own.

A thorough understanding of the car's tire system, run-flat technology, and alternative solutions is essential for ensuring vehicle safety. Regular maintenance and knowledge of the car's specific needs can help drivers make informed decisions and enhance their overall driving experience.

Remember, the absence of a spare tire does not necessarily mean a vehicle is unsafe. Run-flat tires and alternative solutions provide effective protection. However, knowing how to handle a flat tire is important, regardless of whether you have a spare tire or not.
