Is It Normal for the Steel Rim Inside New Car Tires to Rust?
2 Answers
It is normal for the steel rim inside new car tires to rust. Reasons: The rust at this stage is only surface rust, as the steel rim is made of cast iron, which generally does not affect the normal use of the rim. Many car models use aluminum alloy for wheel hubs. The advantage of aluminum alloy is that it is sturdy and durable, but the downside is that it is sensitive to acid. During daily use, simply keep it away from acidic environments. Additional Notes: Many car manufacturers have improved their processes to reduce the harm of acidic substances to aluminum alloy wheel hubs. Currently, the vast majority of car wheel hubs are basically resistant to acid. However, there are still a few car models whose wheel hubs are prone to corrosion.
Last time when I took my car to the 4S店 for maintenance, the technician mentioned this issue to me. Rust on new car's steel wheels is actually quite common, especially in the brake disc area of steel rims. When rainwater or car wash water seeps in, the surface of the iron components will oxidize and turn yellow. As long as it's not deep corrosion where the entire wheel hub is rotting, it basically doesn't affect driving safety. However, it doesn't look good after all, so you can regularly wipe the inner side with a soft cloth to keep it dry. If you're in a coastal city with high air humidity, or frequently drive on saline-alkali land, you need to be even more careful. After all, the wheel hub is an important component that supports the entire car, so it's always good to pay more attention to it in daily life.
