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.

BIS Certification for Passenger Car Pneumatic Tyres – Radial & Diagonal Ply Compliance Guide

Passenger car tyres play a vital role in ensuring vehicle safety, performance, and driving comfort. In India, these tyres must comply with strict quality and safety standards defined by the Bureau of Indian Standards (BIS).

This guide explains everything you need to know about BIS certification for passenger car pneumatic tyres, including radial and diagonal ply tyres, applicable standards, testing, and approval process.

What are Passenger Car Pneumatic Tyres?

Passenger car pneumatic tyres are air-filled tyres designed for cars to provide:

  • Shock absorption
  • Better road grip
  • Load-bearing capacity
  • Smooth driving experience

These tyres are broadly classified into:

1. Radial Tyres

  • Layers run radially (90° to direction of travel)
  • Better fuel efficiency
  • Longer lifespan
  • Improved road grip

2. Diagonal (Bias Ply) Tyres

  • Layers arranged diagonally
  • Strong sidewalls
  • Suitable for rough road conditions
  • Lower manufacturing cost

Both types must meet BIS standards before being sold in India.

Applicable BIS Standard for Passenger Car Tyres

The primary Indian Standard is:

IS 15636: Pneumatic Tyres for Passenger Cars

This standard covers both radial and diagonal ply tyres and specifies:

  • Tyre dimensions and load capacity
  • Speed ratings
  • Construction requirements
  • Performance and endurance criteria
  • Testing procedures
  • Marking and labelling norms

Compliance with IS 15636 is mandatory under the ISI Certification Scheme.

Why BIS Certification is Mandatory

BIS certification ensures that tyres:

  • Meet safety and durability requirements
  • Perform reliably under Indian road conditions
  • Reduce the risk of tyre-related accidents
  • Comply with legal regulations
