To prevent a suitcase from tipping over, you must master the art of strategic weight distribution. The most effective "high-value" peer tip is to place your heaviest items—such as shoes, boots, toiletries, and denim—at the very bottom of the bag, as close to the wheels as possible. This lowers the center of gravity, creating a stable anchor that resists forward or side-leaning tilts. Furthermore, ensure that the weight is balanced horizontally; avoid concentrated heavy items on just one side. When attaching a "personal item" to the handle of a rolling bag, use a luggage strap to secure it tightly against the main handle so it doesn't swing and shift the balance. If you are using a four-wheel "spinner" bag, try pushing it beside you rather than pulling it at an angle, which keeps all four wheels grounded. Finally, ensure your suitcase is fully packed; empty space allows contents to shift during transit, which can suddenly throw off the balance and cause the bag to topple when you let go of the handle.
