Eco Info
What your tyre choice really means for the environment.
Rolling resistance accounts for approximately 20% of a vehicle's fuel consumption. Moving from a Class C to a Class A on the European label represents up to 0.3 l/100 km saved, or several hundred kg of CO₂ avoided over the lifespan of the set of tyres.
Durability is the second lever: a tyre that lasts 20% longer reduces raw materials consumed and waste generated by the same amount. Correct pressure (monthly check), a timely swapped set, and healthy alignment extend tyre life much more effectively than any rubber choice.
Wear particles and rolling noise complete the picture: tyres with the best noise rating (dB) and the most abrasion-resistant compounds limit non-exhaust emissions, which are becoming the main source of pollution from electric vehicles.
Optimal energy efficiency: optimize your fuel consumption and reduce the cost per kilometre of your vehicles.

Your situation
You drive a Porsche Cayenne, model year 2019 onward. The specified tyre size is 285/40 R21 109Y. West Yorkshire has 122 days below 7°C, 52 frost days, moderate ice risk, 18 days of snowfall and 150 days of rain. The terrain is moderately pronounced (▲▲), with seven days above 30°C.
Summer, winter or all-season
Your preference is one set of all-season tyres. However, the local comparison strongly favours separate summer and winter sets: ★★★ versus ★ for rain, handling, light snow and mountain snow. The page therefore recommends two sets, changed in November and March.
There is no Mountain Law requirement and no UK legal obligation stated here. Still, 122 cold days, frost and snowfall make 3PMSF certification important. If convenience is your priority, a 3PMSF all-season tyre remains consistent with your preference. For the strongest weather-specific performance, choose separate summer and winter sets.
Mileage and running costs
At 10,000–20,000 km per year, durability and fuel efficiency are meaningful considerations. The displayed consumption assessment favours winter tyres (€), followed by all-season (€€), then summer tyres (€€€). With one all-season set, monitor wear carefully because the same tyres cover the full annual mileage. Regular rotation can help even out wear.
Recommended tyres
•Continental AllSeasonContact 2 — 285/40 R21 109Y: matches the specified indices, is 3PMSF-certified, and has EU labels B for fuel and B for wet grip. Scores: global 74, ecology 75, economy 60.
