Tyre Testing in India: BIS Standards, Tests and Process Explained

• Tyre testing means checking a new tyre in a lab for size, marking, strength, endurance and speed performance.
• In India, tyres for motor vehicles come under BIS rules and need the ISI mark.
• Different standards apply for two/three-wheeler, passenger car and commercial vehicle tyres.
• Testing is done on samples, and the lab report becomes part of your BIS application.
• Small mistakes like wrong markings or wrong rim can fail a sample, so check before you send.

Introduction

Think of a pressure cooker. You trust it in your kitchen because someone tested it for pressure before it was sold. Tyres are the same, just with much higher stakes. A tyre carries the full weight of the vehicle at high speed, in heat, rain and bad roads.

That is why tyre testing matters. It is not just paperwork. It is how a tyre proves it is safe to sell.

In this blog, we will explain tyre testing in very simple words. You will see which standards apply, what tests are done, how the process works and what mistakes to avoid.

What Is Tyre Testing?

Tyre testing is a set of lab checks done on new tyres. The lab checks if the tyre meets the rules given in the Indian Standard for that tyre type.

In simple words, the lab asks a few basic questions:

• Is the tyre the right size, and is it marked properly?
• Is it strong enough to handle pressure?
• Does it last under long running at a set load and speed?
• Does it stay safe at higher speeds?

Tyres for motor vehicles are covered under a Quality Control Order. This means a maker or importer cannot just sell them freely. The product needs BIS certification and has to carry the ISI mark. The testing report from a recognised lab is a key part of getting that certification.

Which Standards Apply to Tyre Testing?

The standard depends on the type of vehicle the tyre is made for. BIS revised the main tyre standards in 2022, so always use the latest version.

Standard	Type of tyre it covers
IS 15627:2022	Pneumatic tyres for two and three-wheeled motor vehicles
IS 15633:2022	Pneumatic tyres for passenger car vehicles (diagonal and radial ply)
IS 15636:2022	Pneumatic tyres for commercial vehicles (diagonal and radial ply)
IS 13098	Inner tubes for automotive tyres

Simple example: if you make scooter tyres, IS 15627 is your base standard. If you make truck tyres, you will look at IS 15636. A car tyre brand will work with IS 15633.

There is one more thing. Automotive standards like AIS-142 also talk about tyre performance, such as rolling resistance, wet grip and noise, for different tyre classes. Whether and how they apply to your product should be checked with the latest rules before you plan your testing.

---

Why Is Tyre Testing Important?

• Road safety: A bad tyre can burst or lose grip. Testing reduces that risk.
• Legal need: Without BIS certification, you cannot legally sell notified tyres.
• Brand trust: Buyers and fleet owners trust marked and tested products.
• Fewer returns: Problems caught in the lab are cheaper than problems found on the road.
• Smooth market entry: Dealers and OEMs often ask for proof of compliance.

What Tests Are Conducted in Tyre Testing?

The exact list changes with the standard. But most tyres go through these basic groups of tests.

Test	What the lab checks	In simple words
Tyre marking	Size, load index, speed symbol, brand, tubeless or tube type, date code	Is all the information printed correctly on the sidewall?
Tyre dimensions	Section width, overall diameter	Does the tyre match the size it claims?
Tread wear indicator	Marks inside the tread grooves	Will the driver know when the tyre is worn out?
Strength test	Plunger energy, tyre is pushed with a rod until it breaks or reaches a limit	Can the tyre handle a hard hit without giving way?
Endurance test	Tyre runs on a drum at set load, speed and time	Will the tyre last under long, tough running?
Load and speed performance	Running at higher speed steps	Does it stay safe when the vehicle goes fast?
Bead unseating resistance	Pressure on the sidewall of tubeless tyres	Will the tyre stay on the rim when the vehicle turns hard?
Dynamic growth	Growth of tyre size under pressure, as per the standard	Does the tyre swell too much while running?

Note: Not every test applies to every tyre type. For example, bead unseating is for tubeless tyres, and dynamic growth is linked to specific tyre categories. Always read the exact clauses of your standard.

Two Kinds of Tyre Testing: Factory Lab vs Recognised Lab

This point confuses many people, so let us keep it simple.

• Factory lab testing: This is the in-house testing you do in your own plant. It checks routine quality again and again. Under BIS, a manufacturer needs proper in-house test facilities as per the scheme.
• Recognised lab testing: This is testing done by a BIS-recognised or accepted lab on your sample. The report goes with your application.

Both are needed, just for different reasons. Factory testing keeps daily quality in control. Recognised lab testing proves your product to BIS.

Step-by-Step Process for Tyre Testing and BIS Registration

1. Find your standard. Check if your tyre falls under IS 15627, IS 15633 or IS 15636.
2. Check your tyre details. Size, ply type, tubeless or tube type, load index and speed symbol should be final.
3. Prepare the markings. Print or mould all required marks on the sidewall.
4. Do pre-testing in your own lab. Catch obvious problems before the official test.
5. Select the recognised lab. Make sure the lab has the right scope for your standard.
6. Send samples. Send the right number of samples with the right rims and details.
7. Get the test report. The lab checks each clause and gives a report.
8. Apply for BIS certification. Submit documents and the test report on the BIS portal.
9. Factory inspection and grant. BIS may inspect your factory. After the review, the licence decision is taken.

Which BIS Route Is Needed?

The route depends on who you are.

Who you are	What you generally need
Indian manufacturer	BIS product certification licence for your factory
Foreign manufacturer	Foreign Manufacturers Certification Scheme (FMCS) licence
Importer	Goods must come from a BIS-licensed manufacturer and carry the ISI mark
Private label brand	Tyres should be made by a licensed factory and follow the marking rules

A new licence or an extension may also be needed when you add a new tyre size, change the factory location or change the product type. Check with the rules at that time.

Documents Required

Company documents

How Long Does Tyre Testing Take?

There is no fixed number of days that fits everyone. It depends on the tyre type, the number of sizes, the lab queue and how ready your documents are. Endurance and high-speed tests run for many hours, so you need to plan time for them too.

Tip: Ask your lab for a rough schedule before you send samples. Then plan your launch after that.

What Decides the Cost of Tyre Testing?

We are not giving a fixed amount here, because it changes from case to case. These factors decide the cost:

• Type of tyre (two-wheeler, car or truck)
• Number of sizes and variants to be tested
• Number of samples
• Lab charges for each test
• Re-testing if a sample fails
• Transport and handling of samples

If you want a clear breakup for your case, ask your consultant or lab for a written quote.

Common Mistakes in Tyre Testing

• Wrong or missing sidewall markings
• Using a wrong rim during the test
• Sending samples with different build from the production tyre
• Skipping pre-testing in your own lab
• Using an old version of the standard
• Not keeping calibration records of machines
• Sending incomplete documents to BIS
• Forgetting that changes in size or factory need an update with BIS

Most of these are easy to fix, if you check them before sending samples.

---

Who Needs Tyre Testing?

• Manufacturers: Anyone making tyres in India for covered vehicle types.
• Importers: Anyone bringing tyres from other countries to sell in India.
• Private label brands: Brands that get tyres made by another factory.
• Overseas makers: Foreign factories that want to supply tyres to India.
• Export-only units: Rules may differ here, so check your case before you start.
