Giti Tire’s response highlights a wider engineering shift, abrasion must now be managed alongside grip, efficiency, noise and service life.

Vehicle-emissions policy has traditionally concentrated on what comes out of the exhaust. Euro 7 widens that frame. For the first time in European Union vehicle regulation, tire abrasion and brake-particle emissions are brought into the same emissions discussion as pollutants from the powertrain. That matters because tire wear occurs whether a vehicle is powered by petrol, diesel, batteries or another technology.

The practical consequence is a change in what counts as environmental tire performance. Rolling resistance and durability remain important, but regulators are also moving towards a common measure of how much tread material is lost during use. The objective is not to eliminate wear (friction between the tire and road makes some material loss unavoidable), but to identify and limit products with comparatively high abrasion.

Why abrasion has moved onto the regulatory agenda.

Tire particles are produced as tread rolls and slides against the road. Much of the debris combines with road material and is deposited on or near the road, where runoff can move it into soil and water. A European Commission Joint Research Centre review describes tire wear as contributing between one-third and one-half of unintentionally released microplastics, while also stressing that measured emissions vary with the tire, vehicle, road, weather and driving behaviour.

Those variables make the subject more complicated than a single laboratory headline. A heavy vehicle driven aggressively on abrasive roads will not produce the same result as a lighter vehicle driven smoothly under different conditions. Tire pressure, wheel alignment, load and temperature can also influence wear. Regulation therefore requires a repeatable testing framework that can compare products while controlling, or at least accounting for, the conditions around them.

What Euro 7 changes?

Regulation (EU) 2024/1257 establishes the legal framework for tire-abrasion limits and phases the requirements by tire class. Current European Commission research describes the timetable as beginning with C1 passenger-car tires in 2028 and C2 light-commercial-vehicle tires in 2030; the regulation provides a later phase for C3 bus and truck tires. The detailed test procedures and limit-setting work are being developed through the United Nations vehicle-regulation process used by the EU.

For passenger-car tires, researchers have evaluated two candidate approaches: an on-road convoy method and a laboratory drum method. In the on-road procedure, candidate and reference tires are run over approximately 8,000 kilometres, with their relative material loss used to calculate an abrasion index. A 2025 JRC study applying the convoy method to summer and winter C1 tires found a wide range of abrasion rates and estimated service-life values. That spread is precisely why a standard method and defensible limits matter.

The regulatory timetable should not be confused with an immediate consumer label showing a simple abrasion grade. The European Commission states that abrasion and mileage information are intended to be added to tire labelling once suitable testing and classification methods are available. Type-approval limits and consumer-facing label information are related developments, but they are not the same instrument or necessarily introduced at the same moment.

The engineering challenge is balance, not wear alone.

A tire cannot be optimised for one target without considering the others. Compound changes that reduce wear may alter wet grip, rolling resistance, low-temperature behaviour or noise. Reducing tread depth can lower some forms of energy loss, yet it may also reduce the distance available before the tire reaches its legal wear limit. The European Commission describes these attributes as competing properties, requiring engineers to balance safety, efficiency and environmental performance rather than chase one maximum in isolation.

This is the central technical challenge created by Euro 7. A low-abrasion tire that gives away too much wet performance would not represent a credible outcome. Neither would a durable product that imposes an unnecessary energy penalty. The strongest development programmes will be those that lower material loss while preserving the complete performance envelope expected for the tire’s intended vehicle, climate and use case.

How Giti Tire is positioning for the change.

In its July 2026 statement, Giti Tire outlined its response to the Euro 7 tire-abrasion framework, pointing to work in compound development, tread-pattern optimisation, rolling resistance, longevity and manufacturing consistency. The company presents the regulation as a continuation of its existing approach to balancing tire performance rather than as an isolated compliance project.

That is a reasonable engineering direction, but the published announcement has a clear evidence boundary. It does not provide measured abrasion rates, identify tested reference tires, publish a compliance certificate or list specific Giti products that have passed a final Euro 7 limit. Its claim of readiness should therefore be reported as the company’s position and development intent, not as independent proof that every current product is compliant.

The distinction is especially important because regulatory methods and limits have continued to evolve. A manufacturer can be organisationally prepared through testing capacity, compound research and product-development processes before a final product approval is available. Readers should expect future product-level evidence to include the relevant tire class, size, category, test method, limit and approval scope.

Why the change matters beyond manufacturers

For vehicle makers, abrasion becomes another requirement to integrate into homologation and efficiency work. For fleets, better wear performance may eventually support lower replacement frequency and lifecycle cost, although those outcomes depend on operating conditions and cannot be inferred from an abrasion claim alone. For drivers, the regulation creates a stronger basis for comparing environmental performance, but it does not remove the need to select the correct specification and maintain it properly.

Inflation pressure should follow the vehicle manufacturer’s placard or owner’s manual. Alignment problems, overloading and harsh acceleration or braking can cause premature or uneven wear regardless of the tire’s laboratory classification. Euro 7 sets expectations for the product; maintenance and driving conditions still influence what happens on the road.

A new definition of cleaner mobility.

Euro 7’s significance is broader than a new test. It recognises that road-transport emissions do not disappear when the exhaust pipe does. As powertrains become cleaner and electrification expands, non-exhaust sources account for a larger share of the remaining environmental burden. Tire engineering is therefore moving from an indirect sustainability conversation focused mainly on fuel or energy efficiency to direct accountability for material loss during use.

Giti Tire’s announcement places the company inside that transition, but the meaningful proof will come at product level as final limits, test methods and approvals are applied. The standard to watch is not simply whether a tire wears slowly. It is whether abrasion can be reduced without compromising the grip, control, efficiency and durability that drivers depend on throughout the tire’s service life.
