Independent tyre comparison for transport fleets — evaluated on safety, annual cost per trailer, and rubber deposited into the environment. Because tyre selection is not just a purchasing decision.
Three parameters. One decision.
What we measure for your fleet
Every tyre comparison from TPT covers three parameters — because a tyre that is cheap to buy but wears twice as fast, or deposits twice the rubber into the environment, is not the right choice regardless of purchase price.
S
Safety
Grip performance measured across the full tyre lifespan. We report best case, worst case, and average — because predictability matters as much as peak grip. A tyre with unpredictable degradation is a safety risk even when its average looks acceptable.
Measured: µ at all wear states · braking distance spread
€
Cost
Expected tyre life in km and purchase price combined into a cost-per-trailer-per-year figure. The cheapest tyre to buy is rarely the cheapest tyre to run — a tyre that wears faster needs replacing more often, and the extra replacement cost easily exceeds any purchase price advantage.
Measured: km per tyre life · replacements per year · total annual cost per trailer
E
Environment
Rubber particles deposited into the environment per kilometre — measured by volume and mass. In one comparison the wrong tyre deposited more than twice the rubber per km. Now a regulated metric under Euro 7.
Measured: rubber volume and mass loss per km
Euro 7
Rubber deposit is now a regulated parameter
EU Regulation 2024/1257 — adopted April 2024 — includes tyre rubber particle deposition as a formally measured environmental parameter for the first time in European legislation. Testing methodology follows UNECE UN R117. Mandatory compliance for truck and trailer tyres (C2/C3 class) begins from April 2030 for new type approvals. Fleet operators who can already demonstrate measured rubber deposit data per tyre type are ahead of the curve — and TPT001 produces exactly this data today, tested on real road surfaces.
Safety — real test data
What µ means for braking distance
Friction coefficient (µ) directly determines how quickly a truck can stop. The difference between a well-matched tyre and a mismatched one is not just a number on a chart — it is metres of stopping distance, at every point in the tyre's lifespan.
TPT001 safety data — short distance routes
Braking Distance vs. Tyre Life
Stopping distance from 80 km/h across the full tyre lifespan. Top of chart = shorter stop = safer. Lower end = longer stop = risk. Short-distance routes, real TPT001 data.
Type Green remains stable across its lifespan — braking distance stays within a 1.3m window. Type Orange deteriorates significantly: a worn Type Orange takes over 7 metres longer to stop than a worn Type Green from the same speed.
TPT001 safety data — predictability comparison
Braking Distance Spread Across Lifespan
Best vs. worst case stopping distance across the full tyre lifespan. A wide spread means unpredictable braking — the driver never knows which tyre they have. Real TPT001 data.
A larger spread means the driver never knows which tyre they have under braking. Type Orange swings 15.2 metres between its best and worst case — Type Green only 5.5 metres. That unpredictability is a safety risk independent of the average performance figure.
TPT001 environmental data — short distance routes
Rubber Deposit into the Environment
Normalised rubber volume loss per km across tyre lifespan. Type Green new tyre = 100% baseline. Lower = less rubber deposited = better for environment. Real data from TPT001 2025.
The 316% spike at 67% wear for Type Orange is not an error — it shows what happens when a long-distance tyre is used in high-slip urban conditions as it wears. Type Orange deposits on average twice the rubber into the environment per kilometre compared to the correctly matched Type Green. That is tonnes of microplastic rubber per year across a fleet of 150 trailers.

Expected Tyre Life (km)
Average expected kilometres per tyre across the diagonal wear path in short-distance conditions. Real data from TPT001 2025.
Longer tyre life means fewer replacements per year. Combined with the lower purchase price of a correctly specified tyre, switching to Type Green for short-distance routes saves €318 per trailer per year across this fleet — without any reduction in safety.

Annual Tyre Cost — Fleet Total
Based on 950 tyres/year, 80% split, 3% puncture rate = 783 tyres/year. Type Orange €415/tyre · Type Green €360/tyre.
Type Green costs more per tyre but fewer are needed per year because they last longer on short-distance routes. The net result is €47,738 saved annually across the fleet — €318 per trailer.

Matching tyre to route
Short distance vs. long distance
The most common and costly mistake in fleet tyre selection is using a long-distance tyre on short-distance routes. TPT001 tests both profiles separately.
Short distance
Regional & Urban Distribution
High-slip conditions dominate — cornering, stopping, acceleration. A long-distance tyre in short-distance conditions wears twice as fast and deposits twice the rubber per km — while being less predictable in emergency braking.
Long distance
Motorway & Long-Haul
Sustained speed with low slip but higher thermal load. Fuel efficiency label has measurable cost impact at scale. Rubber deposit per km is lower but still a regulated parameter under Euro 7 — and Type Green outperforms here too.
