The Nissan Qashqai now comes equipped with a cost-saving new tyre for 18in-wheeled models.
Nissan claims the low-resistance tyre brings the running costs of those cars down to that of cars with smaller 17in wheels. Larger alloys traditionally cause the car to have higher CO2 emissions.
The new tyres reduce the CO2 output of Qashqais in Acenta Premium Pack, N-Connecta and N-Vision specs by 4g/km, but reduces the emissions of the dCi 130 2WD Xtronic by 6g/km. All of the spec levels which have been subject to the tweak have also had their benefit-in-kind (BIK) tax bands reduced by 1%.
In addition to this, the vehicle excise duty (VED) of DIG-T 115 2WD manual, DIG-T 115 2WD Xtronic and dCi 130 4WD manual have also been downgraded, meaning a £130 saving per year for each.
A Nissan spokesman was unavailable to comment whether the tyres are more expensive than those they replace, or if models with other sizes of alloy may benefit from a similar tyre down the line.
