Car models with spare tires mounted on the rear door include: Chery Tiggo, Pajero, RAV4, FJ Cruiser, Wrangler, Mercedes-Benz G500, Mercedes-Benz G55 AMG, Landwind X6, and many more. In the early days, cars did not have spare tires. However, with the use of pneumatic tires in automobiles, issues such as flat tires and loss of air pressure became obstacles to normal vehicle operation. As a result, car inventors quickly recognized this problem, leading to the creation of the spare tire in the automotive world. Below are the functions of car tires: 1. Supporting the entire weight of the vehicle: Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions. 2. Transmitting traction and braking torque: Transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the vehicle's power, braking, and off-road capabilities; working together with the car's suspension to mitigate impacts during driving and dampen resulting vibrations. 3. Preventing damage to car components: Preventing car components from suffering severe vibrations and premature damage, adapting to the vehicle's high-speed performance and reducing driving noise, ensuring driving safety, handling stability, comfort, and fuel efficiency.

As a car owner who enjoys taking weekend trips to the mountains with my family, I've driven several vehicles with spare tires mounted on the rear door. The most common one is the Prado, whose design positions the spare tire high up, making tire changes effortless without bending over; the Jeep Wrangler is also very popular, especially the modified off-road versions, where the spare tire placement is convenient for emergency fixes in the wild; and the Suzuki Jimny, though compact, has a practical rear-mounted spare tire. During daily driving, I've found this layout saves trunk space, making it much easier to load luggage. The downside is the added weight to the rear door, which over time may cause the door hinges to loosen, and occasional noise on bumpy roads. I recommend regularly checking the spare tire lock to ensure it's secure and preventing rust issues, especially if you frequently drive on muddy roads. Overall, it's quite suitable for travel enthusiasts.

As a car enthusiast, I'm very familiar with rear-mounted spare tire models. The Land Cruiser Prado has always been a classic choice, with its rear-door spare tire design being super practical; Jeep Wrangler models across generations have popularized this configuration, which perfectly matches its off-road style; Land Rover Defender offers rear-mounted spare tire versions in both new and old models; even some older Ford Broncos came this way. This design originates from driving needs, as the elevated spare tire position makes it less likely to hit obstacles off-road. The advantages include quick tire changes, while the downside is reduced rear visibility and the risk of scraping against poles when parking in the city. I love that rugged look, but modern cars are using it less frequently because it increases fuel consumption. During maintenance, I recommend paying attention to spare tire rack corrosion and applying anti-rust treatment to prolong its lifespan.

From a daily driving perspective, I haven't seen many models with spare tires mounted on the rear door. The Prado is one example, where the spare tire's hanging position makes it easy to access; the Jeep Wrangler is also common, suitable for off-road terrain. This design primarily aims to save interior space, but weight issues can make the rear door prone to damage. When driving, ensure the spare tire is secure to avoid loud noises over bumps. In cities, parking can be inconvenient, with limited visibility and potential theft risks. Maintenance is simpler—just regularly check the fasteners.

I'm a bit older and drove vehicles with rear-mounted spare tires like the Prado and Jeep Wrangler in earlier years. Back then, having the spare tire mounted on the rear door was quite popular, making tire changes during off-roading more convenient and safer. However, opening and closing the rear door requires more effort, which might be awkward for elderly people to operate, and the exposed spare tire is prone to dust accumulation and rust. It's recommended to perform regular cleaning to reduce the risk of corrosion.

As a driver who often commutes in the city, I occasionally see vehicles with spare tires mounted on the rear door, such as the Prado or Jeep Wrangler with this configuration. The exposed position adds style, but it causes parking difficulties in urban areas, poor visibility, takes up a lot of space, makes trunk access inconvenient, and the spare tire may be stolen or corroded. It also requires more effort to maintain, with regular checks needed on the mounting hardware to ensure safety.
