Product Testing Institute (PTI)
Environmental Ratings
Supporting a more sustainable tyre industry through responsible testing, compliance and informed decision-making.
What Are Environmental Ratings?
Environmental ratings help assess the environmental impact of products throughout their lifecycle, from raw materials to disposal.
In the tyre industry, these ratings focus on:
- Energy efficiency
- Rolling resistance
- Material use and waste
- Durability and product lifespan
- End-of-life recovery and recycling potential
Environmental ratings enable policymakers, manufacturers and consumers to make informed decisions based on sustainability goals, cost of ownership and environmental performance.
Independent Testing for Quality and Sustainability
PTI was established to champion independent product evaluation as a catalyst for quality and sustainability.
By providing trusted environmental and product ratings, PTI empowers society to demand better, more responsible products.
Working as an independent laboratory alongside manufacturers, government, and academic institutions, PTI not only tests products but actively contributes to the development of innovative solutions that enhance quality while minimising environmental impact.
Frequently Asked Questions
Do environmental ratings impact tyre approvals?
Not currently mandatory in South Africa, but environmental metrics like rolling resistance may influence global and future regulatory frameworks.

PTI provides accredited technical testing relevant to environmental performance, such as rolling resistance and durability, but does not issue environmental labels.
How do I know if my tyre meets circular economy principles?
By assessing energy performance, durability, retreadability, and end-of-life recyclability.
Can PTI guide manufacturers on sustainability?
PTI provides technical data that supports sustainability planning, but does not serve as a policy advisory body.
