What kind of wheels are better for suitcases?

One-way wheel is one-way push, which has the advantage of being suitable for all kinds of road conditions, and the wheel is bigger and stronger. The disadvantage of one-way wheels is that they can only go in one direction and have to move when turning.

The universal wheel rotates and moves 360 degrees, which makes it easier and more convenient to pull up on a flat road, and can also be pushed sideways when passing through a narrow place at an airport or station. But now there are also directional universal wheels.

Aircraft wheels are made of rubber. Because they have eight sides, they are very stable and make little noise when pushed. Aircraft wheels have the disadvantages of large contact area with the ground and high friction, so the efficiency of aircraft wheels is not as good as that of four wheels. ?

If the ground of the tourist destination is not rugged, airplane wheels and universal wheels can be used. If it is rugged roads such as towns, railway stations and bus stations, it is best to use a suitcase with one-way wheels to ensure that a box of bricks is pulled and the broken wheels of the suitcase are not bad.
