Knobby Tire - Street Use

Street Use

Depending on the model of tire, a knobby tire may or may not be approved by the DOT. A knobby tire approved for street use is referred to as a "DOT knobby" or a "D.O.T. knobby." The markings on the sidewall of a DOT knobby include a DOT code (U.S.) with the last four digits representing the week and year the tire was built, which identifies the tire as street legal. If the knobby tire has markings like "Motocross Use Only" or "Not for Highway Use", then the tire is not street legal. Even if street legal, knobby tires are generally not suitable for long distances on roads or paved surfaces, because the pavement wears down the knobs and ruins the tires for off-road use.

Famous quotes containing the word street:

    The invention of photography provided a radically new picture-making process—a process based not on synthesis but on selection. The difference was a basic one. Paintings were made—constructed from a storehouse of traditional schemes and skills and attitudes—but photographs, as the man on the street put, were taken.
    Jean Szarkowski (b. 1925)

    Think of admitting the details of a single case of the criminal court into our thoughts, to stalk profanely through their very sanctum sanctorum for an hour, ay, for many hours! to make a very barroom of the mind’s inmost apartment, as if for so long the dust of the street had occupied us,—the very street itself, with all its travel, its bustle, and filth, had passed through our thoughts’ shrine! Would it not be an intellectual and moral suicide?
    Henry David Thoreau (1817–1862)
