Tire bead is the term for the edge of a tire that sits on the rim. Wheels for automobiles, bicycles, etc. are made with a small slot or groove into which the tire bead sits. When the tire is properly inflated, the air pressure within the tire keeps the bead in this groove. Reducing tire air pressure is a frequent practice among off-road vehicle ...
The bead is a thicker section of rubber, and is reinforced with braided steel cables, called the bead bundle. [1] The surface of the bead creates a seal between the tire and rim on radial and bias-ply tires. Often, the bead can become stuck to the rim after rusting or corrosion occurs, requiring the use of a bead breaker in order to be removed.
Forensic tire tread evidence records and analyzes impressions of vehicle tire treads for use in legal proceedings to help prove the identities of persons at a crime scene. Every tire will show different amounts of tread wear, and different amounts of damage in the form of tiny cuts and nicks.
Tire maintenance for motor vehicles is based on several factors. The chief reason for tire replacement is friction from moving contact with road surfaces, causing the tread on the outer perimeter of tires to eventually wear away. When the tread depth becomes too shallow, like for example below 3.2 mm (4/32 in), the tire is worn out and should ...
Low tire pressure applications such as off-roading and drag racing use a beadlock that clamps or physically attaches the bead of the tire to the rim of the wheel. This reduces the chance of the tire separating from the rim, causing a sudden deflation. [9] Material Various metals can be used for the rim.
Beads are bands of high tensile-strength steel wire encased in a rubber compound. Bead wire is coated with special alloys of bronze or brass. Coatings protect the steel from corrosion. Copper in the alloy and sulfur in the rubber cross-link to produce copper sulfide, which improves bonding of the bead to the rubber. Beads are inflexible and ...
Studded mountain bike tires for icy conditions. Off-road tires used in mud or dirt feature individual knob patterns to allow the tire to bite into the surface and lever the sides of the tread to get a better grip. Given the smaller contact patch, these tires tend to wear quickly when used on asphalt (depending on type of rubber).
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...
