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 ...
This heat compromises the internal structure of the tire which can lead to a blowout. When a tire is over-inflated, it wears the tread down faster, and becomes more prone to catching nails or screws in the tire. The best way to check tire maintenance is to check the air pressure, because that will lead you to whatever problem your tire might have.
Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in 1978, a branch of the United States Department of Transportation (DOT). [ 1 ]
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
Tire load sensitivity describes the behaviour of tires under load. Conventional pneumatic tires do not behave as classical friction theory would suggest. The load sensitivity of most real tires in their typical operating range is such that the coefficient of friction decreases as the vertical load, Fz, increases.

This also means significant reductions in greenhouse gas emissions. A car tire has 40% natural rubber and 60% oil based rubber, a retreading of tires will reduce the need for natural rubber significantly. In addition to reducing the amount of raw materials extracted, retread tires also minimize the amount of waste that ends up in landfills.
Besides puncturing of the tire a flat can be caused by: failure of or damage to the valve stem; a nail in the tire; rubbing of the tire against the road; ripping of the tire; separation of tire and rim by collision with another object; excessive wear of the tire tread allowing explosive tire failure or road debris tearing through the tire. Some ...
