Who decided to put wheels on suitcases?

For those not familiar with the terminology, a spinner suitcase is an upright bag with four wheels (as opposed to roller luggage, which has only two wheels). While it's absolutely not always the case, spinner suitcases are often hard-sided, while roller bags are more often soft-sided.

Spinner luggage is more susceptible to breakage because the wheels move in different directions. This is especially true when you're rolling over uneven surfaces like cobblestone. The wheels on upright luggage, on the other hand, tend to be more durable because they don't move around as much.

In a two-wheel design, the wheels tend to be larger than the wheels on 4-wheel models, so they roll forward in a straight line better than 4-wheeled bags, thanks to the sheer physics of their size. If speed is your highest priority, choose a 2-wheeled bag.

Number of Wheels - 2, 4, or 8 Some spinner luggage even comes in eight-wheeled options. Doubling up the spinner wheels on each corner of the rolling bag gives the luggage added durability and stability. Plus, eight wheels sharing the work lowers the chances for ever needing wheel repairs or replacements.

Re: Carry On Bags - Do the Wheels Count? The box itself does consider the wheels to be a part of the dimensions of the bag. The same goes for the overhead bins as well. Personally, I would make sure that the entire suitcase, including wheels, matches those dimensions for it to be a carry-on.
