Tyre Fuel Efficiency Rating
EU tyre labels rate fuel efficiency from A (best) to G (worst). Select your current and potential new tyre ratings to see the difference.
Tyre Pressure
Under-inflated tyres increase rolling resistance and waste fuel. How many PSI below the recommended pressure are your tyres?
Most cars lose 1-2 PSI per month naturally. Check your pressure monthly.

The Science
How Tyres Affect Your Fuel
Rolling Resistance
Tyres account for roughly 20% of your car's total fuel consumption through rolling resistance — the energy lost as your tyre deforms against the road.
A vs G Rating
The difference between the best (A) and worst (G) EU fuel efficiency rated tyres is 7.5% in fuel consumption. That's hundreds of dollars per year.
Per PSI Lost
Every 1 PSI of under-inflation across all four tyres costs you 0.2% in fuel economy. Most cars lose 1-2 PSI per month naturally.
Why This Matters More in NZ Right Now
With 91 petrol averaging $3.20/litre and predicted to hit $4/litre, fuel is the single biggest running cost for most NZ drivers. The government is offering $50/week cash relief for some families — but the smartest long-term move is reducing how much fuel you burn in the first place. Your tyres are the easiest place to start.
