In a candid interaction with Tyre Trends, freelance tyre testing specialist Juuli Raatikainen shares her views on the intricacies of tyre testing, the role of women in the industry, simulation and the road ahead, reports Nilesh Wadhwa.

“Women have been driving cars for decades, so why not be part of the tyre and automotive testing industry? I believe the bigger question and challenge is how the industry (tyre and automotive) can think beyond gender. The tyre testing industry is huge, but there are not many direct studies to learn about it and become part of it,” remarked Juuli Raatikainen, the 28-year-old test driver and mechanic who has been offering freelance services for tyre testing for the last four years.

INITIAL JOURNEY

It is no secret that tyre testing is not a widely known field. A simple internet search for the world’s top 10 racers or motorsport celebrities will return mostly male sports personalities.

For Raatikainen, the journey into tyre testing began as a test assistant in Lapland, Finland.

“I started my career as a test assistant. My passion for testing grew, and I was eager to learn more, working hard to gain knowledge. My efforts were noticed, and I received the necessary support. The decision to start my own company and operate as a freelancer was quite easy for me. In the first two years, I focused on gaining experience, testing time and learning as much as possible. I wanted to see tyre testing from different angles, companies and drivers. Today, I am happy to say that I have experience in tyre testing operations as a tyre mechanic, test assistant, instrumentation specialist and objective test driver. I am also engaged in testing tyres and vehicles for events and magazines,” she shared.

THE EVOLVING ROLE OF TYRE TESTING

Tyre testing has evolved over the years, from physical and mechanical assessments to indoor methods, including Tyre-in-the-Loop (TiL) testing, a form of hardware-in-the-loop (HiL) simulation. However, despite technological advancements, many tests still need to be conducted in real-world conditions to determine optimal solutions.

For example, a vehicle travelling in a sandy environment at a particular tyre pressure will have different braking times even at the same speed. The steering response, traction at different corners and slippage will also vary.

“I find simulators to be a good tool for all drivers and for hardware development. However, no one knows exactly how they will impact testing in the future. Many questions remain, and some conditions and types of tests cannot yet be simulated accurately. As a test driver, my main expertise is in winter testing. From my experience, winter conditions are particularly difficult to replicate artificially. Winter is a living, breathing element of nature, making it hard to forecast, as conditions can change very quickly,” she explained.

For tyre manufacturers, real-world testing is essential for finding the right conditions and weather. For instance, summer tyres cannot be tested in winter, nor can Nordic spike tyres be tested in warm conditions. “It is a challenge for companies to run tyre tests year-round and across different locations. Agility is key,” Raatikainen added.

Tyre testing falls into two main categories: objective and subjective. Objective testing relies on instruments to assess tyre performance, while subjective testing depends on the driver’s evaluation.

“As a freelancer, I work across different processes. Transparency with clients is my priority. It’s about what I do and how I do it. Trust is one of the key values I bring to the table,” she explained.

KEY LEARNINGS & TYRE SAFETY

As a test driver, Raatikainen has firsthand experience of how tyre choices impact performance and safety in different conditions.

“Statistics show that one of the most common mistakes drivers make is using the wrong type of tyres for their environment and weather conditions. When selecting tyres, it’s crucial to consider two key questions: Where will I be driving, and in what weather conditions? These simple considerations can significantly impact safety,” she added.

Most tyres have a wear indicator on the tread to signal when they need replacement, but these warnings are often ignored.

According to data from the Ministry of Road Transport & Highways (MoRTH), India recorded 461,312 road accidents in 2022, resulting in 155,781 fatal cases. Despite tyres having a significant influence on vehicular control, they are rarely cited as a primary cause of accidents.

When replacing tyres, it is also crucial to check their manufacturing date. Raatikainen emphasises that even a ‘new’ tyre must be evaluated based on its production date, as rubber degrades over time, regardless of use.

“Regularly checking tyre condition is just as important as choosing the right type. Ensure tyres have adequate tread depth, are free from cracks or bulges and are properly inflated. These simple maintenance habits can extend tyre life and improve safety,” she added.

FUTURE TRENDS IMPACTING THE TYRE INDUSTRY

New-age vehicles and tightening regulations are pushing industry players towards sustainability and reducing their carbon footprint.

For the tyre industry, environmentally friendly sourcing, production and materials remain key focus areas. From a tester’s perspective, what does the future hold?

“I am excited about advancements in simulation technology and their impact on the tyre industry. Another major trend is the growing emphasis on indoor testing for winter tyres, which addresses unpredictable weather challenges and helps distribute testing workloads more efficiently,” she said.

A third emerging trend is smart tyre technology.

“While modern vehicles are equipped with advanced systems, tyres have yet to integrate similar innovations. The questions of when this technology will arrive, how it will develop and what features it will bring are incredibly exciting. I look forward to seeing how smart tyres will enhance safety, performance and the driving experience,” Raatikainen concluded.
