The tyres are the ones the car is fitted with as built and recorded as such.
The reason it makes a differece is because the additional rolling and wind resistance uses more fuel so creates more Co2.

^^^ What DM said ^^^

That's why cars like the Polo Bluemotion have dead skinny tyres - too reduce drag, which reduces load on the engine, and therefore improves fuel economy and emissions.

Even losing air-con helped to take the bob-basic Bluemotion beneath the 100g/km threshold.

I've been looking into a SMART just lately and it surprised me that there's no difference in emissions between the 61bhp Pure without aircon and fitted with dinky tyres, and the posher 71bhp with aircon and relatively wider sporty-tyres. All 116 g/km
