Wheels also are available in a variety of hardnesses usually measured on the durometer 'A' scale. Wheels range from the very soft (about 75a) to the very hard (about 99a). As the scale stops at 100a, any wheels labelled 101a or higher are harder, but do not use the appropriate durometer scale. Some wheel manufacturers now use the 'B' or 'D' scale, which has a larger and more accurate range of hardnesses.

Even larger wheels are used in longboarding and downhill skateboarding. Sizes range from 65mm right up to 100mm. These extreme sizes of wheels almost always have cores of hard plastic that can be made thinner and lighter than a solid urethane wheel. They are often used by Skateboard filmers or videographers, as the large soft wheels allow for smooth and easy movement over any terrain.
