Two wheels or four (spinner) wheels for a rolling tote?

Two-wheel inline designs are typically lighter, more durable on rough pavement, and roll well behind you, while four-wheel spinners are easier to push upright down narrow airline aisles. Specialist travel subreddit threads we read consistently note that spinner wheels add weight and have more failure points, while two-wheel designs like the Maxlite 5 are praised for being lightweight. For grocery and utility totes, four caster wheels are generally preferred so the bag can be pushed upright when fully loaded.
