The company describes its business philosophy as producing quality products at reasonable prices using international-standard technology.2

Foundation (1977)

Deestone was established in 1977 by Suvit Vongsariyavanich with the objective of developing Thailand’s domestic tyre industry. At the time, the local market was dominated by a small number of foreign manufacturers, and the company aimed to provide a Thai-manufactured alternative capable of delivering quality tyres for domestic consumers.3 Early manufacturing activities focused on truck, industrial, and motorcycle tyres, sectors where durability and practical operating characteristics were essential.

Expansion during the 1980s–1990s

The Deestone group gradually expanded both its manufacturing base and product portfolio. A significant addition was Deerubber Co., Ltd., established in 1982, which began producing motorcycle tyres, tubes, solid tyres, and industrial products.4 In 1996, Deestone International Co., Ltd. was formed to manufacture commercial vehicle, industrial, agricultural, and other specialty tyres, eventually offering more than 1,000 sizes across various categories.5 This period marked the transition of Deestone from a focused domestic manufacturer into a broader tyre production group.

Entry into passenger car radial tyres (2007)

A major technological milestone occurred in 2007 when the group established Svizz-One Corporation Co., Ltd., originally associated with Deestone’s radial tyre operations. This provided a dedicated manufacturing base for automotive radial tyres, enabling the company to compete more directly in the passenger car and light vehicle segments.6

Truck radial production (2014)

In 2014, Deestone established Siam Truck Radial Co., Ltd. to focus on truck and bus radial (TBR) tyres. This investment represented a significant shift from traditional bias-ply commercial tyres to modern radial technology for heavy vehicles.7

Creation of Deestone Corporation (2016)

Deestone Corporation Co., Ltd. was established in 2016 as a trading and distribution company serving both domestic and international markets. This development further structured the group around specialized manufacturing entities supported by a dedicated commercial organization.8

Deestone operates as a group of related companies involved in different areas of tyre production and distribution rather than as a single factory. According to corporate information, the major affiliated companies include:

Deestone Co., Ltd.

Founded in 1977, this is the original company of the group. Its manufacturing portfolio includes large truck tyres, medium and light truck tyres, and industrial tyres. The company employs approximately 1,100 staff.9

Deerubber Co., Ltd.

Established in 1982, Deerubber specializes in motorcycle tyres, motorcycle inner tubes, solid tyres, and industrial tyres. It employs approximately 800 staff.10

Deestone International Co., Ltd.

Established in 1996, this company manufactures a broad range of products including truck tyres, light and medium truck tyres, industrial tyres, agricultural tyres, and specialty tyres. It produces more than 1,000 sizes across relevant product categories.11

Siam Truck Radial Co., Ltd.

Established in 2014, Siam Truck Radial specializes in truck and bus radial tyres (TBR).12

Deestone Corporation Co., Ltd.

Established in 2016, this company focuses on the commercial side of the tyre business, including domestic and international trading.13

A defining characteristic of Deestone is the breadth of its tyre portfolio, which covers multiple transportation and industrial segments rather than focusing exclusively on passenger cars.14

Passenger car tyres

Deestone manufactures radial tyres for passenger cars, sedans, hatchbacks, SUVs, pickups, and 4×4 vehicles. The passenger and light vehicle radial range includes products designed for comfort and low noise, high-speed performance and grip, and off-road use.15

Truck and commercial tyres

The company maintains a substantial commercial vehicle business covering heavy trucks, medium and light trucks, buses, commercial vehicles, truck and bus radial tyres, and bias-ply commercial tyres. This segment has historically been one of Deestone’s core strengths.

Motorcycle and bicycle tyres

Deestone and Deerubber manufacture motorcycle tyres, scooter tyres, motorcycle inner tubes, and other two-wheel applications. The group also produces bicycle tyres and related products.

Agricultural and industrial tyres

Agricultural products include tyres designed for machinery and equipment. For industrial applications, the company manufactures various tyres including specialty and solid tyre products. The portfolio also includes tyres for forklifts and other off-road or industrial equipment.

Deestone’s manufacturing model relies heavily on vertical integration and the use of Thai natural rubber. The company uses natural rubber sourced from Thailand alongside synthetic rubber, textile and canvas materials, and steel wire.16 The manufacturing process begins with Banbury mixing, where natural and synthetic rubbers are combined with chemicals under controlled conditions before being transformed into components required for tyre construction.17

The general manufacturing chain includes rubber mixing, milling, component preparation, tyre assembly, vulcanization or curing, finishing, and quality inspection. This integrated approach allows the company to manufacture tyres for diverse applications using varying rubber compounds, constructions, and tread designs.

Deestone has pursued certification and regulatory approval in multiple international markets. Corporate information lists certifications and standards including ISO 9001, DOT requirements for the United States, E-mark requirements for European markets, Thai Industrial Standards (TIS/Mor.Or.Kor.), SIRIM in Malaysia, and other national and regional standards. Testing procedures involve measures such as plunger energy, endurance, and force variation to evaluate tyre performance and manufacturing quality.18

The company states that its products have achieved recognition in more than 120 countries and that its five affiliated production companies provide an annual capacity of up to approximately 250,000 tonnes.19

Although fundamentally a Thai company, Deestone has developed export markets across Southeast Asia, other parts of Asia, Europe, the Middle East, Africa, and North and South America. An important part of its international strategy involves supplying both proprietary brands and private-label or OE-type commercial products in certain markets. Distributor networks facilitate the supply of a broad range of tyre products to more than 100 countries.20 The company currently cites a global market reach of more than 120 countries.21

Deestone

Deestone is the group’s principal consumer-facing brand, covering applications ranging from passenger cars and pickups to motorcycles, trucks, agricultural machinery, and industrial equipment. Its market positioning is based on Thai manufacturing, a broad product range, competitive pricing, and adherence to international standards.

Thunderer

Thunderer is another tyre brand associated with the Deestone group. It is used particularly in international markets and contributes to the group’s multi-brand strategy.22

Deestone occupies a distinct position in the global tyre industry as a large independent Thai manufacturer with significant export activity. While not comparable in global scale or brand recognition to the largest multinational manufacturers, it leverages several competitive advantages including a long manufacturing history, access to Thai natural rubber, a large manufacturing base, a wide product portfolio, experience in commercial and specialty tyres, competitive manufacturing costs, international certifications, and an extensive export network. Its particularly broad coverage of truck, agricultural, motorcycle, and industrial tyres distinguishes it from companies focused solely on passenger car tyres.

Deestone states that it attempts to minimize manufacturing waste by reusing rubber left over from production rather than treating it as waste. This approach is described as part of an effort to make factories more environmentally friendly and reduce their impact on surrounding communities.

The central philosophy expressed by Deestone is the production of quality products at reasonable prices using international-standard technology. This reflects the company’s historical role in creating a Thai alternative to foreign tyre manufacturers while developing products capable of competing in export markets. The company also emphasizes cooperation among employees, local communities, and government institutions as part of its development.

This table represents a high-level market positioning comparison rather than a ranking of tyre quality. Deestone’s differentiation lies in large-scale Thai manufacturing, cost competitiveness, product diversity, and export capability rather than imitation of premium European or Japanese brands.

Deestone represents one of Thailand’s major examples of a domestically developed manufacturing company competing internationally. Beginning in 1977 with the objective of providing a domestic alternative to foreign producers, it developed manufacturing capabilities spanning passenger vehicles, commercial vehicles, motorcycles, agriculture, and industrial applications over subsequent decades. Its development aligns with Thailand’s status as a major natural rubber-producing country, connecting the nation’s agricultural raw material base with higher-value industrial manufacturing through the use of locally sourced natural rubber.

As of 2026, Deestone is a Thai-owned, internationally oriented tyre manufacturing group headquartered in Samut Sakhon with multiple manufacturing companies producing tyres for passenger vehicles, motorcycles, trucks, buses, agriculture, and industrial applications. Corporate materials state that the group has more than 50 years of development, serves users in more than 120 countries, and has an annual production capacity of approximately 250,000 tonnes across five affiliated production companies. The company’s headquarters is located at 84 Moo 7, Soi Petchkasem 122, Petchkasem Road, Om Noi, Krathum Baen, Samut Sakhon 74130, Thailand.

Deestone is recognized as one of Thailand’s major homegrown tyre manufacturers, having expanded from truck and motorcycle tyres into passenger car radial and truck radial products, and now exports a broad range of tyres to more than 120 countries.
