The spare tire is located at the rear of the vehicle or under the car chassis. A spare tire is a backup tire prepared for the car. In case one of the tires gets punctured or encounters an issue, the spare tire allows for timely replacement, preventing the car from breaking down midway. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground contact and rolling. They are typically installed on metal rims to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during operation. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption capabilities.

I've been driving for many years and have seen various spare tire locations. The most common is hidden under the trunk floor, visible when lifting the cover, sometimes mounted on the sidewall of the trunk. Different car models vary - my old sedan had the spare tire hanging on the undercarriage frame, requiring the use of onboard tools to unscrew it. The location design saves space and maintains interior tidiness. Nowadays many vehicles use foldable or inflatable spare tires for lighter weight. Remember to regularly check spare tire pressure - measure it every six months to ensure it functions properly in emergencies. Insufficient pressure makes it useless during high-speed blowouts. When locating the spare, first consult the vehicle manual to identify its position, and avoid rough movements when retrieving it to prevent injury. This practical design conveniently handles unexpected situations.

The spare tire is usually placed under the floor in the trunk or mounted externally on a rear rack like in SUVs. The variation in placement is due to automakers optimizing weight distribution and interior space. Having studied automotive design, I can confirm this arrangement lowers the center of gravity for better stability and prevents trunk congestion. Specifically, sedans often conceal it under the floor, while off-road vehicles may have it mounted underneath with tool-released mechanisms. Spare tires come in full-size or compact folding types—the latter being lightweight but having shorter lifespans, requiring regular checks. Changing a spare is straightforward: find a safe spot, engage the parking brake, use a jack to lift the wheel, then remove it. Don’t panic if the location differs; just consult the manual. A spare tire cover protects against dust and aging—give it a glance occasionally to ensure it’s ready when needed.

The spare tire is located in the trunk of the car, usually secured under the floor cover, and in some vehicles, it's mounted on an undercarriage rack. I once had to retrieve the spare tire when driving my kids around, and it was so heavy that I had to be careful not to strain my back. This placement is designed to keep the cabin clean and make it easily accessible, with little variation across different car models. Regularly check the tire pressure to ensure it's adequate, and top it up if necessary to avoid any awkward situations during emergencies. When changing a tire, always park on a flat surface for safety. The spare tire cover is designed to prevent dirt and damage.
