Most of the mileage change comes from different speeds used winter/summertime. I have absolutely the same mileage when I switch to studded tyres but still drive summertime limits (100km/h). When the wintertime speed limits (80km/h) come and I drive them, I get better mileage. Summetime range is ~900km/80l and wintertime is 1000km/80l on my volvo s80 (this is what computer says and I'm never actually close to emptying the tank, it usually only takes 55l at 700-800km mark)
