HOW ARE TYRES ARE MADE?

FLANKS:They link the tread with the bead area. They also absorb deformations and contribute to a tyre’s strength, shape, and feedback.

BEAD LEDGE WIDTH:The tyre fits perfectly on the rim which is held by pressure and clamping of the wire rope. Helps driving and braking.

BEAD WIRE:They are metal wires that make up the inside of the tyre’s circumference. They help in the celebration with the tyre.

INNER TYRE LINER:There is no inner tube in tubeless motorcycle tyres – instead, a thin layer of butyl rubber included inside the tyre acts as a tube containing ‘air’, it is similar in the case of tube tyres.

CROWN PLY:Adds strength and protection for the tyre. Hidden underneath the tread, it is composed of up to a textile cord covered in rubberized fabrics that resist deformations caused by speed and load, and also protects other parts of the tyre from damage.

CASING PLY:Provides reinforcement around the entire tyre and is connected to the cord cables. Together with the side wall of the tyre PLY casing helps to maintain shape and absorbs warping.

Before the production begins, we work hard on research and development, from the rubber compound to the tread pattern thereby ensuring that the end product meets our client’s/clients’ expectations.

The compound which is  a mixture of black carbon, rubber and certain accelerators in the Banbury is passed through rollers to achieve a uniform appearance. As the mix passes through rollers, the rubber compound is gradually cooled to provide the desired dispersion. Meticulous compound storage, coding and cooling systems guarantee uniform as well as foreign substance free materials for the extrusion process.

The compound is then passed through the tube extruder line and inner tube slicer in  delicate, error free and controlled manner. Strict supervision of the tube curing presses (with different heating mediums) and the core fitting machine maintains good surface finish and ensures that the vulcanization process is carried out the right way.

Post the entire process; batch of tyres go under rigorous tests at ETDAC (Eastman tyre development and analysis centre) where both off road and street tyres are tested for high speed endurance, durability tested via plunger and tensile testing machines. They are also subjected to abrasion test, to measure resistance.

Another test includes, ash content test is done to measure organic material content.

In a nut shell, we ensure quality by

●Dimensional measurements of tyre overall width, tyre overall diameter, skid depth, etc
●Tyre strength test (plunger test)
●Endurance test
●High speed performance test & % dynamic growth test
●Physical properties of sidewall & rubber
●Tensile strength test
●Elongation test
After all tests, we move ahead on production of the entire lot.
