Process of Making Tires
HOW A TIRE IS MADE
As many as two hundred different raw materials combine into a unique mix of chemistry, physics and engineering to become a tire.
For illustration
Materials used:
Rubbers: 1) Natural rubber( obtained from hevea tree)
RSS ribbed smoke sheet ( RSS 4 is used )
SIR ( standard Indonesian rubber)
SMR( standard Malaysian rubber)
2) Synthetic rubber Butyl rubber ( import from russia) 30 kg each bale. SBR 1502 (light yellow) styrene-butadiene rubber (Mostly used in bead wire compound) SBR 1712 (oil extended rubber) (Import from Korea Used in tred and ply compound)
3. PBR (orange yellow rubber) poly-butadiene rubber (made in iran) EPDM ( eyhylene propylene diene monomer) Compounds in which load (strength) is requirement SBR is used and if load and speed both is required PBR is used. 3) Reclaim rubber ( vulcanized rubber) : Butyl reclaim ( import from india) Natural reclaim (50 kg each bag) Natural and butyl rubber cannot be mixed so their setup is separate. Bale cutters and mixers are also separate. To increase the heat resistance of natural rubber it is blend with SBR Strength of 1502 is greater than 1712 Butyl rubbers are used to make tubes. Butyl colours are used to stick on compounds Hexane is used to separate rubber which stick to each other
4. Fillers ( mechanical holding strength increases): Reinforcing fillers: 1) Carbon black N-220 N-330 N-339 N550 N-660 Particle size of N330 < N660 55 bags in each palate each of 25 kg. Non- reinforcing fillers: (cost reducing) 1) CaCO3 2) China clay 3) Crumb( recycled rubber from tyre scrap) Activators: 1) ZnO 2) Stearic acid Plasticizers (increase fluidity): 1) Aromatic oil (thick oil green in colour, highly viscous) 2) Paraffin oil (white oil) 3) Napthenic oil (colourless) Retarders (anti scorching): 1) PVI/CTP ( pre vulcanization inhibitor)
5. Accelerators: 1) TMTD 2) MBTS 3) MBT 4) CBS 5) TBBS

The basic steps of tire manufacturing process:
MANUFACTURING
The production process begins with the selection of several types of rubber along with special oils, carbon black, pigments, antioxidants, silica, and other additives that will combine to provide the characteristics wanted. Separate compounds are used for different parts of the tire.
Banbury Mixer: Banbury mixer combines the various raw materials for each compound into a homogenized batch of black material with the consistency of gum. The mixing process is computer-controlled to assure uniformity. The compounded materials are then sent to machines for further processing into the sidewalls, treads or other parts of the tire.
Assembling the tire: The first component to go on the tire building machine is the innerliner, a special rubber that is resistant to air and moisture penetration and takes the place of an inner tube. Next come the body plies and belts, which are often made from polyester and steel. Plies and belts give the tire strength while also providing flexibility. The belts are cut to the precise angle and size the tire engineer specifies to provide the desired ride and handling characteristics. Bronze-coated strands of steel wire, fashioned into two hoops, are implanted into the sidewall of the tires to form the bead, which assures an airtight fit with the rim of the wheel. The tread and sidewalls are put into position over the belt and body plies, and then all the parts are pressed firmly together. The end result is called a “green” or uncured tire.
Last step - Curing of the tire. The “green” tire is placed inside a mold and inflated to press it against the mold, forming the tread and the tire identification information on the sidewall. Then it is heated at more than 300 degrees Fahrenheit for twelve to fifteen minutes, vulcanizing it to bond the components and to cure the rubber. (This twelve to fifteen minute curing process is for passenger and light truck tires. Off-road and large tires may take up at a day to cure).
Inspection: Every tire is then inspected, and sample tires are randomly taken from the line and tested. Some are x-rayed, some are cut apart to look for flaws, others are run on test wheels, or road-tested to evaluate handling, mileage and traction performance.
Every tire is carefully inspected, and random samples are pulled for additional safety tests. As part of these tests, tires are x-rayed, cut apart and examined, run on test wheels, or road-tested to evaluate handling, mileage and traction performance.
If properly cared for, tires can last a long time – usually from 40,000 to 80,000 miles, depending on the application.

The Amazing Ways Goodyear Uses Artificial Intelligence, Industry 4.0 Technologies And IoT For Digital Transformation
Goodyear uses internet of things technology in its Eagle 360 Urban tyre. The tyre is 3D printed with super-elastic polymer and embedded with sensors. These sensors send road and tyre data back to the artificial intelligence-enhanced control panel that can then change the tread design to respond to current road conditions on the fly and share info about conditions with the broader network. If the tyre tread is damaged, the tyre moves the material and begins self-repair. The tyre has the ability to monitor and track tyre pressure, vehicle data, and road conditions. This data is then analysed by Goodyear’s algorithms to gain insights about maintenance needs and ways to improve the safety and performance of the fleet.
The Oxygene model, another 3D-printed tyre has embedded sensors connected to the internet of things and also uses living moss and photosynthesis to power its electronics. The self-generated electricity powers onboard sensors, an AI-processing unit, as well as a light strip that illuminates when a driver brakes or changes lanes. The tyre is printed from rubber powder from recycled tyres.
Goodyear has focus on the advancement of mobility-focused on connected, autonomous, and electric vehicles.
At the operational level, Goodyear has also leveraged the power of technology to increase its productivity.
Goodyear is running an internet of things proof-of-concept using sensor data from the factory floor to inform maintenance needs. Investments in workplace modernization is taking place in Goodyear operations (in more than 150 countries, 48 manufacturing facilities and research and development centres in Germany, Luxembourg, China, and the United States). The company is also exploring how Microsoft HoloLens and other technologies could impact virtual tyre modelling and design.

Six-sigma application in tire-manufacturing company: a case study
Vikash Gupta, Rahul Jain, M. L. Meena & G. S. Dangayach
Journal of Industrial Engineering International volume 14, pages511–520(2018)
Wastage of material is happening due to variation in the bead splice of a tire. This wastage is financial loss to the organization. Therefore, variations in the bead splice has to be reduced to minimize the wastages. The value of process capability index C pk is calculated to be 0.94 which is less than 1.
The Ishikawa diagram was used for finding the root cause of the problem.
First cause of the problem was bead splice setting on higher side caused by slippage of bead tape from gripper. The slippage of bead tape from gripper was generated due to worn out of the griper key.
Second cause was variation in the advancer setting caused due to change in skill of worker. This man-to-man variation was caused due to lack of the standard setup guidelines available.
The third cause was related to the frequency of sensor setting. Setting of sensor is required frequently as the former diameter changes. However, due to non-availability of guideline, sensor setting could not change frequently.
The last cause was that the workers were not using the measuring tape.
For the the root causes, the corrective actions were taken. The capability index C pk value is improved to 2.66
