BKT Tires produces more than 2,400 models of OTR tires, ranging from those used on small utility vehicles to large agricultural, construction and surface/underground mining tires. With the startup of its newest plant, the company is setting its sights on establishing a larger market presence in the giant OTR tire sector.
It’s a market in which several well-known brands dominate the premium giant tire sizes used on mining-class rigid haul trucks and wheel loaders, for example. And, it’s a market in which BKT Tires is working diligently to expand its presence.
BKT, the brand name for products and services from Mumbai, India-based Balkrishna Industries, has been a major player in the radial agricultural tire market since 2004, offering more than 230 different agricultural tire sizes. In 2008, it moved into the OTR steel-cord radial market segment that serves much of the mining, quarrying and heavy construction industries’ tire needs, opening a plant in Chopanki, India, to make tires specifically for those applications.
More recently, it built a $500 million, state-of-the-art OTR tire manufacturing complex in Bhuj, Gujarat, India. In December, Coal Age toured the plant and talked with corporate executives during the company’s December business press/dealer event, titled The Game Changer, held to announce and display its intent to gain a leadership position in the market as it expands its capabilities for producing giant OTR tire models. Currently, its largest tire in this segment is the 27.00R49 EarthMax — a size typically used on 100-ton-class rigid haulers in the mining sector. However, as production at the Bhuj plant gains momentum, the company said it will begin to manufacture 51-in. tires later this year using tire fabrication equipment supplied by Tianjin Siaxiang Technology Co. Ltd., a Chinese vendor. BKT also is considering future production of 57-in. tires; D.M. Vaidya, BKT’s president and director technology, estimates it would require a two-year effort to develop a marketable product in that size — if economic conditions warrant. There are no current plans to produce tire sizes larger than 57 in., according to Vaidya.
From Trikes to Trucks
As BKT Chairman and Managing Director Arvind Poddar explained during an early December press conference in Mumbai, the company has come a long way since his father founded it in 1954, initially producing bicycle tires for the Indian domestic market, and later, tires for the heavier tricycle vehicles widely used throughout the country for public transportation. Output has risen from 10 metric tons per day (mtpd) to 600 mtpd and will grow to 800 mtpd by 2017. The company’s product portfolio includes more than 2,400 SKUs — all OTR tires, as it doesn’t make any products for on-highway applications. Its radial and bias-ply OTR lines include models for rigid and articulated haulers, wheel loaders, graders and several types of underground mining vehicles, as well as non-mining applications ranging from port equipment and cranes down to lawn and garden care utility vehicles.
BKT’s $500 million Bhuj plant will, at full capacity, produce about 150,000 metric tons per year of tire products, which equals the combined output of its three other plants.
The size and scope of the Bhuj plant gives the strongest hint of the company’s market-leadership aspirations; it encompasses more than 300 acres, of which 72 acres are taken up with roofed central plant facilities, and also includes the country’s only OTR test track along with a 25,000-sq-ft research and development facility, plus worker and visitor accommodations and a dedicated power plant. Its location in the windswept, desert environment of this region was mainly due to the need for efficient logistics arrangements, besides offering the best prospect for finding a sufficiently large land parcel. The Bhuj plant was built just 60 km away from the port of Mundra, located on the Gulf of Kutch in the Arabian Sea. It is India’s largest private port facility and can handle some of the shipping industry’s deepest-draft container vessels.
Although it is only operating at slightly less than half of its capacity right now, eventually the plant will output 325 mtpd of tire products, representing an annual output of more than 150,000 mt. (In comparison, BKT’s three other plants produce 150,000 mtpy combined.) To achieve these production levels, it needs large quantities of basic tire-making materials such as carbon black, crumb rubber, soft clay and other materials, sourced from suppliers in several countries.
In addition, Poddar said BKT has pursued supplier certification from major mobile mining equipment OEMs such as Caterpillar, and is intent on securing further certifications from others in order to vault from its current status as a replacement-tire provider to an OEM outfitter. The ability to supply large volumes of tires to meet OEM requirements is a necessity for meeting certification standards, and BKT believes the Bhuj plant’s location and logistics setup is well-suited to achieve that goal.
“The Bhuj production site is a milestone in BKT’s growth,” said Lucia Salmaso, managing director of BKT Europe. “Not only for its high levels of technical and quality standards, but also because it is the BKT plant that is situated nearest to a port, a decisive factor to speed up delivery time. Likewise, this is a great benefit for companies that have chosen BKT tires as original equipment.”
BKT said it churns out more than 300 tire molds each year, enabling it to provide very short development-to-market cycles.
Putting It All Together
Construction of the plant began in early 2011 and the first tires were produced a little more than a year later — although the plant won’t be fully completed until the end of this year.
Inside the production facility, a visitor’s first visual impression is of seemingly endless, thick ribbons of rubber emerging from the facility’s 13 high-capacity mixers — the largest mixer facility in India — as the machines blend various combinations of raw ingredients fed by an automated charging system designed to provide high levels of product consistency and quality. From that stage on, the process involves both machine-assisted and manual application of numerous internal components included in each tire model’s design. For the 27.00R49 EarthMax, 59 components — ranging from small special-purpose rubber strips to steel-reinforced fabric layers and metal bead rings — are needed to complete each tire. All raw tire assemblies eventually reach the curing stage, where they are heated under pressure in custom molds to produce a final product with the correct shape, dimensions and tread pattern. In the case of the 27.00R49, curing takes nine hours, and the plant can produce three of these tires per day.
The largest tire produced by the Bhuj plant currently is BKT’s 27.00R49 EarthMax model for large earthmovers, but it has plans to produce 51- and possibly 57-in. tires in the future.
A soon-to-be-completed R&D facility at Bujh will enable the company to study, test and validate new tire compound formulations, component designs, tread patterns and performance parameters. The R&D center will house three tire test wheels ranging in size from 1.5 m to 5 m in diameter.
To further improve quality, BKT has a continuous monitoring process that collects account feedback from distributors and on-the-job reports from end users. These monitoring activities are carried out by technical support teams assigned to global regions in cooperation with BKT’s field technicians who visit customers to check tire conditions, pressure, wear and product life-cycle status.
“Our ultimate goal is to achieve leadership in the OTR market worldwide” through continuous evolution of products and services, said Poddar.
