Cars usually place spare tires in the following locations: under the trunk mat, mounted on the chassis, or mounted on the rear of the vehicle. Spare tires are classified as follows: 1. Full-size spare tire: A full-size spare tire has exactly the same specifications and size as the other four tires on the vehicle and can replace any one of the tires that are temporarily or permanently unusable. 2. Non-full-size spare tire: This type of spare tire has a slightly smaller diameter and width than the other four tires and can only be used as a temporary replacement. It should only be used on non-driving wheels, and the maximum speed should not exceed 80 km/h. 3. Run-flat tire: Run-flat tires, also known as safety tires, are commonly referred to as "puncture-proof tires" and are directly translated in the industry as "tires that can run when flat." Compared to ordinary tires, run-flat tires do not leak air or leak very slowly when punctured, maintaining their driving profile. The tire bead also remains fixed on the rim, allowing the car to continue driving stably for an extended period or temporarily until reaching a repair station. Therefore, vehicles equipped with such tires no longer need to carry a spare tire, effectively hiding the spare tire in another form within the four tires.

I know quite a few spare tire locations, usually under the floor of the car trunk. Just lift the mat and you'll see it. Having driven a family sedan for years, I've had to do this every time I change a tire—super convenient and doesn't take up extra space. Nowadays, some new car designs are quite clever, hiding the spare tire securely to protect it from dust and rain. SUVs or off-road vehicles might hang the spare tire at the rear or under the chassis, secured with a chain, requiring special tools for removal. The key is to regularly check the spare tire's condition, like whether it's properly inflated or if the rubber has aged. Ignoring it means it might be useless in an emergency. I recommend lifting the trunk mat monthly to check the spare, ensuring proper tire pressure, so you can drive with peace of mind. Don't wait until something happens on the road to regret it.

The spare tire is usually stored under the trunk floor, accessible by lifting the cover, but be careful not to strain your back when removing it. I always remind myself to wear gloves when checking the spare, especially since dirt can hurt your hands. For trucks or large vehicles, the spare is often mounted under the chassis and requires tools to lower it slowly—handle it carefully to avoid dropping it on your feet. Remember, the spare is only for temporary emergency use; drive no more than 80 kilometers before switching back to the original tire, as driving faster can be dangerous. Make it a habit to check the owner's manual to locate the spare and regularly test its pressure to ensure it's usable, so you don't end up stuck with a flat tire on the road.

The spare tire location varies by vehicle type: in compact cars, it's often under the trunk floor, visible when you lift the cover; SUVs and off-road vehicles may have it externally mounted on the rear or suspended underneath; pickup trucks typically secure it beneath the frame. I know some vintage Jeeps mount the spare tire on the rear door, which looks pretty cool. Identifying your vehicle type is key to avoid panic during tire changes. Don't neglect your spare – check its pressure once or twice a year.
