Tyre Performance Technology — Passenger Cars

Road tyres
under scrutiny.

Independent compound testing for all-season, summer, and winter passenger car tyres. What a tyre does when new tells only part of the story — TPT measures the full lifespan.

What TPT001 reveals

The gap between
new and worn

Most passenger car tyres are tested and marketed based on new-tyre performance. The TPT001 method measures what actually happens across the full wear lifespan — and the differences between brands are often most significant precisely where the tyre has been on the car for 18 months or more.

01
Initial grip is not the whole story
In our 4-season compound test, the tyre with the highest initial friction coefficient dropped to the worst performance when fully worn. The tyre that started with less grip maintained the most stable performance across its entire lifespan.
02
Thermal aging changes the ranking
When heat exposure is added to the wear model, rankings between brands change significantly. A tyre that performs well when new and cool may behave very differently after two years of use — which is when most drivers are still relying on it.
03
Top brands are not always equals
Three top-market all-season tyres from leading suppliers — marketed as equivalent products — showed substantially different compound behaviour across their lifespan. The TPT001 method makes those differences measurable and visible.
04
The right choice depends on use
A tyre used mainly in warm conditions and replaced frequently has a different optimal compound profile than one used year-round for two years in a northern climate. The compound wear model identifies which tyre suits your specific use pattern.

Friction Coefficient vs. Rubber Wear
Three top-market all-season tyres under identical conditions. Pre-heated to 70°C. Each point = average of 6 repeated tests.
New 50% worn Fully worn 0.90 1.05 1.20 1.35 Rubber thickness reduction over tyre life
Type Green — most stable across full lifespan, best when worn
Type Orange — highest grip when new (above µ 1.35), steepest decline when worn
Type Grey — consistent mid-range decline throughout lifespan
Key findings — fully worn, no thermal input
Type Green
µ 1.12 — highest grip at full wear. Gained performance between new and 50% worn before a gradual decline.
Type Grey
µ 0.98 — mid-range at end of life. Steady, predictable decline from new throughout lifespan.
Type Orange
Above µ 1.35 when new — the highest initial grip of the three. Dropped to µ 0.92 at full wear — the lowest of the three, despite its strong start.
What we test

All-season, summer
and winter tyres

The TPT001 method applies to all passenger car tyre categories. Brand names and tyre designations are kept confidential in all reports — results are referred to by type designation only.

All-season
All-Season Compound Testing
The most complex compound category — optimised for four seasons means compromises across all of them. TPT001 reveals exactly where those compromises sit across the wear lifespan, and which brands manage the trade-offs most effectively.

A tyre that passes all label requirements when new may fall below the performance of a competitor well before the end of its legal service life.
Summer
Summer Tyre Comparison
Summer compounds are designed for peak performance in warm conditions. TPT001 tests across the temperature and abrasion window specific to summer use — identifying which tyres maintain their performance advantage as they wear, and which lose it quickly.

For OEM evaluation and independent research where new-tyre performance alone is not a sufficient basis for selection.
Winter
Winter Tyre Testing
Winter compounds use softer formulations that behave differently under abrasion and low-temperature thermal exposure. TPT001 tests within the relevant temperature window to show how cold-weather compound performance evolves through the full tyre life.

Including environmental rubber deposit measurement — relevant to both urban winter driving and new Euro 7 requirements.
Who uses this service

For researchers,
OEMs and fleets

OEMs & Tyre Manufacturers
Compound wear models for development evaluation — delivered in matrix format or as equations ready to integrate into your simulation environment. Independent testing adds an external reference point to internal R&D findings, and supports claims that need to hold up under scrutiny.
Research Institutions
Academic and independent research requiring measured compound wear data across a defined parameter window. TPT001 provides repeatable, documented test results with full methodology transparency. Results are suitable for publication and regulatory reference.
Fleet & Lease Companies
Passenger car fleets replacing hundreds of tyres per year benefit from independent data on which tyre performs best through its full lifespan. Evaluated on safety, cost-per-kilometre, and rubber deposit into the environment — relevant under Euro 7.
