Push effort & ride comfort
Major design factors that affect wheel selection are:
1. Push effort on smooth floors
The amount of force required to push equipment on smooth floors such as vinyl, commercial carpet and smooth concrete.
2. Push effort on rough floors
The amount of force required to push equipment on rough floors such as bitumen or over obstacles like elevator door jams and joins between tiles and carpet. 
Simple preventative maintenance for your casters will greatly extend caster and wheel life. The following steps will help assure that your casters live up to your expectations and application requirements.
In many cases, caster and wheel products wear quickly by subjection to abusive or unreasonable demands. The most important factor in making your caster and wheel products last is choosing the correct caster for your needs.
