That's an excellent question that many urban residents don't consider until they're struggling with a malfunctioning trash can on their way to the curb. The sturdiness of your rolling trash can wheels largely depends on the specific model and wheel type you have. Most modern urban trash cans feature either hard plastic wheels or rubberized tread wheels - with the latter typically performing better on uneven surfaces.
For rough pavement commonly found in cities, you'll want wheels that are at least 4-5 inches in diameter with some form of shock absorption. The wheel material matters significantly too; thermoplastic rubber (TPR) wheels tend to withstand cracks and bumps better than basic plastic ones. Many municipal trash cans unfortunately skimp on wheel quality, leading to broken axles and difficult maneuvering when the pavement gets rough.
Consider the weight distribution as well - a fully loaded can puts tremendous pressure on those small wheels. If you frequently navigate broken sidewalks or pothole-ridden alleys, look for reinforced wheel hubs and thicker axles. Some premium models even feature all-terrain wheels similar to those on garden carts. Regular maintenance like cleaning debris from wheel wells also extends their lifespan. Ultimately, while most standard trash can wheels can handle smooth surfaces, truly rough pavement demands more robust construction for long-term reliability.
