The rubber strips on both sides of the car roof are sealing rubber strips. Below is a related introduction about the strips on both sides of the car: 1. Function: Rain gutter on the car roof. The rubber strips on both sides of the car roof are sealing rubber strips. If these rubber strips are present, it indicates that the car model does not use laser welding, and the manufacturing process still adopts spot welding + sealing strips in this area. 2. Advantages: Compared to roof racks, they offer numerous conveniences, thus becoming increasingly popular among home and self-driving travel enthusiasts. Wind resistance and noise are far less than roof racks or other mounted equipment. Irregular shapes of roof racks or soft roof-mounted equipment result in greater wind resistance and noise.
The strips on both sides of the roof are actually the mounting rails for the roof rack, called longitudinal rails or crossbars, used for attaching bike racks or cargo boxes. Once, during a family road trip to the mountains with the trunk packed full of snacks and tools, we relied on them to carry two large boxes on the roof, saving a lot of space. Don’t underestimate these small components—they’re quite sturdy, mostly made of aluminum alloy, capable of bearing hundreds of kilograms, making it easy to bring along tents or sports gear. However, ensure they are securely fastened during installation to prevent items from sliding off while driving, which could compromise safety. Nowadays, many SUVs come with this design as standard, like the one in my family, which is very convenient and even saved us highway tolls during the trip by staying within height limits. Just remember not to overload—check the vehicle’s manual for the recommended load capacity to avoid damaging the car.
