Why Gravel or Substrate Is Necessary for an Aquarium
Fish Habitat. Likewise, the infusoria that may be harbored in the gravel bed is a good first food for fry. In addition to reducing stress on the fish, substrates can also be used to improve the chemistry of the water. For instance, if your fish require hard water, a coral substrate will increase water hardness.

What's the best gravel tire? – 10 models in comparison ...
In general, on a perfectly smooth surface, the higher the air pressure, the less the tire deforms and thus the lower the rolling resistance. On gravel and uneven surfaces it's the other way round: the lower the air pressure, the lower the rolling resistance, up to a limit. This applies to gravel roads as well as soft forest floors and meadows.
