BIS Standards for Two & Three Wheeler Tyres – Certification, Testing & Approval Explained

In India’s rapidly growing automotive sector, ensuring the safety and durability of tyres is critical—especially for two and three wheelers, which dominate the roads. To maintain uniform quality and safety, tyre manufacturers must comply with standards set by the Bureau of Indian Standards (BIS).

This blog explains the BIS standards, certification process, testing requirements, and approval guidelines for two and three wheeler tyres in India.

Why BIS Certification is Important for Tyres

Tyres directly impact vehicle safety, fuel efficiency, and performance. BIS certification ensures that tyres:

• Meet safety and durability standards
• Perform reliably under Indian road conditions
• Reduce the risk of accidents due to tyre failure
• Comply with legal regulations

For manufacturers and importers, BIS certification is mandatory before selling tyres in the Indian market.

Applicable BIS Standards for Two & Three Wheeler Tyres

The primary Indian Standards applicable are:

IS 15627

• Pneumatic tyres for two-wheelers (motorcycles, scooters)

IS 15633

• Pneumatic tyres for three-wheelers (passenger & goods vehicles)

These standards define:

• Tyre dimensions and load ratings
• Construction requirements
• Performance parameters
• Testing procedures
• Marking and labelling

Key Requirements Under BIS Standards

To comply with BIS regulations, tyre manufacturers must meet the following:

1. Construction & Design

• Proper tread pattern and depth
• Reinforced sidewalls
• Uniform structure for durability

2. Performance Criteria

• Load-carrying capacity
• Speed rating
• Heat resistance
• Wear resistance

3. Safety Parameters

• Resistance to bursting
• Grip and traction performance
• Stability under different conditions

Testing Requirements for Tyre Certification

Before approval, tyres undergo rigorous testing in BIS-approved laboratories:

Endurance Test

Evaluates tyre performance under continuous load and speed.

High-Speed Test

Checks tyre stability and strength at high speeds.

Bead Unseating Test

Ensures the tyre remains properly fitted to the rim.

Strength Test

Measures resistance to external pressure and deformation.

Tread Wear Test

Assesses durability and lifespan of the tyre.

BIS Certification Process

The certification process under the ISI Mark Scheme includes:

Step 1: Online Application

Manufacturers apply through the BIS portal with product details.

Step 2: Documentation Submission

Key documents include:

• Manufacturing details
• Test reports
• Quality control procedures

Step 3: Factory Inspection

BIS officials inspect:

• Production facilities
• Testing equipment
• Quality assurance systems

Step 4: Sample Testing

Samples are tested in BIS-recognized labs.

Step 5: Grant of ISI License

Upon successful compliance, BIS grants certification and permission to use the ISI mark.

Marking & Labelling Requirements

Certified tyres must display:

• ISI mark
• Manufacturer’s name or brand
• Tyre size and type
• Load and speed rating
• Date of manufacture

This ensures traceability and consumer awareness.

Documents Required for BIS Certification

• Business registration certificate
• Manufacturing unit details
• Test reports
• Quality control documents
• List of machinery and equipment

Benefits of BIS Certification for Tyres

Getting BIS certification offers several advantages:

• ✔ Legal compliance in India
• ✔ Enhanced brand trust and credibility
• ✔ Improved product quality
• ✔ Eligibility for OEM supply and government tenders
• ✔ Competitive advantage in the market

Common Challenges in BIS Approval

Manufacturers often face:

• Complex testing requirements
• Documentation errors
• Delays in approval
• Lack of technical clarity on standards

Professional guidance can help streamline the process and reduce delays.

Conclusion

BIS certification for two and three wheeler tyres under IS 15627 and IS 15633 is essential to ensure safety, performance, and compliance in the Indian market. With strict testing and approval processes, BIS helps maintain high standards across the automotive industry.

For manufacturers and importers, obtaining BIS certification is not just a regulatory requirement—it’s a step toward delivering safe, reliable, and high-quality products to consumers.
