You might notice that most kitchen trolleys use small wheels. While trolleys will be much easier to move around if they have had large wheels, you might wonder why trolley wheels are often small. Well, the primary reason for them to use smaller wheels is that large wheels take up more floor space. As the primary reason why people choose to use trolleys is as a means to save space, it is logical to use small wheels. Secondly, larger wheels raise the height of the trolley. This, in turn, causes the trolley to be less stable.
