While there is no definite answer, the substance that produces the most friction when rubbing up against another substance is almost certainly rubber. This is why it is used in tires.
Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
two rough ones - there will be more friction xx
Rough surfaces do create more friction than smooth surfaces. How much friction is created depends on how rough the surface is.
the rough surface creates more friction as to that of soft surfaced ones
Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.

Rough surface provides lot of friction.
more rough surface more friction object have
friction is produced on rough surface... so like we use oil and Greece to reduce friction because it disconnet the contact of the object from the rough surface.......

Rough surfaces, the rougher the surface, the greater the friction.
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
