GLC260 does not have a spare tire. This is because the GLC260 is equipped with run-flat tires, which allow the vehicle to continue driving even if a tire is punctured, enabling the driver to reach a repair shop for replacement. Definition of a spare tire: A spare tire refers to an extra tire for a passenger car, typically matching the specifications of the original tires. However, some vehicles use specially designed spare tires to remind owners to inspect and replace faulty tires promptly, such as those with distinctive wheel rim colors, compact spares, folding spares, or run-flat tires. Types of spare tires: There are three types of spare tires: full-size spares, non-full-size spares, and run-flat tires. A full-size spare matches the specifications of the other four tires on the vehicle exactly and can replace any temporarily or permanently unusable tire. A non-full-size spare has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary use and exclusively for non-driven wheels. Run-flat tires, also known as safety tires or colloquially as "anti-burst tires," are officially termed "tires that can run while flat" in the industry.

















In the luxury SUV segment like the GLC260, it's indeed common for many models not to come with a traditional spare tire. In my two-year-old GLC260, I only found a tire repair kit and an air pump in the trunk. Mercedes-Benz's official design primarily aims to reduce vehicle weight for better fuel efficiency and to free up trunk space for storage. However, they equip the car with run-flat tires, which are specially reinforced on the sides. Even if punctured by a nail and leaking air, these tires can still allow you to drive about 70-80 kilometers to reach a repair shop. It's advisable to regularly check the tire pressure monitoring system before driving and inspect the tire condition before long trips. In case of a sudden flat tire, the run-flat tires can reliably get you to the nearest service area. Many people aren't aware that they can opt to purchase a non-full-size spare tire for around 2,000 RMB to keep in the trunk as a backup, though this does come at the cost of some storage space.

As a responsible car owner, I can confirm that my GLC260 didn't come with a spare tire when I took delivery. The salesperson explained that now focuses on run-flat tire technology, which allows driving about 80 kilometers even with a flat tire. In practical use, these run-flat tires perform well on paved roads, though you'll feel more noticeable bumps when going over speed bumps. Remember to check the expiration date of the tire repair fluid in the onboard toolkit - it typically needs replacement every two years. Daily maintenance should pay special attention to wheel rim care, as the thick sidewalls of run-flat tires make the rims more prone to deformation if impacted. Once when I had a sidewall puncture, I slowly drove on the run-flat tire to the 4S shop and spent 3,000 yuan on a replacement. If you're really concerned about long trips, you can find portable spare tire racks online, though installation can be somewhat troublesome.

It depends on the specific model year. Post-2021 GLC260 models generally eliminated the spare tire, replacing it with a tire repair kit and run-flat tire combination. However, some early off-road package versions might include a compact spare tire in the trunk compartment. Run-flat tires work well for city driving - I once drove to a repair shop after puncturing my tire on rebar. They cost about one-third more than regular tires though, with replacements exceeding 2,000 RMB. Remember to periodically test the air compressor in your repair kit to ensure it works when needed. While eliminating the spare saves space, I recommend keeping some puncture-resistant gloves in your glovebox for tire inspections.

Driving a luxury SUV like a requires getting used to the no-spare-tire setup. My GLC260 is a typical example: under the trunk divider, there's only a space the size of a first-aid kit, containing a Mercedes-branded tire sealant can and a cigarette-lighter-powered air pump. The advantage of run-flat tires is greater safety during high-speed blowouts, maintaining vehicle stability. However, note that these tires are stiffer - you must slow down for potholes or risk wheel rim deformation. During routine maintenance, have technicians thoroughly check the tire pressure sensors; last time, a faulty sensor caused a false alarm. For long trips, I recommend keeping a portable tire pressure monitor in the car - it responds faster and gives more intuitive readings than the factory system.
