The company owns and operates eight factories in Asia, North America, and Europe and distributes tires and automotive components ...
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 ]
For passenger and light truck tyres, the manufacturers or importers have the choice of either putting a sticker on the tyre tread or a label accompanying each delivery of batch of tyres to the dealer and to the end consumer. The tyre label will use a classification from the best (green category "A") to the worst performance (red category "G").
Most modern cars, SUV and pickup trucks require minimum tyre speed rating of "S" (180kph), but the vast majority of mud-terrain tyres max out at a tyre speed rating of "Q" (160kph). [8] [9] [10] Mud-terrain tyres, may improve traction and have reduced braking distances on dirt roads where the rocks slightly are too big to fit into the grooves ...
The Ladysmith plant began to produce Dunlop truck and bus radial tyres in July 2018, following the second of two large investments by Sumitomo Rubber Industries to upgrade and modernise the plant. Dunlop truck and bus radial tyres produced in Ladysmith will be sold in the South African market and will also be exported to several African states ...
Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.
Tire load sensitivity. 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, increas
