6000 miles a set was the average in my sierra... I've slowed down a bit since then (mostly in order to keep my licence) but the fronts on the Volvo never lasted longer than 12k, and the E class rears have been killed in 10 before now - been doing a lot of motorway and got 20k out of the current ones though.
I get 18.6 mpg on average over the last 14,000 miles. The best I can do on a run is 23.0 mpg, whereas my tyres have been good for over 14,000 miles and still have 4mm of tread on the rears.
15 average in town, no more than 23 at 80mph. I have seen it as low as 12 after short power runs, IMO, you would have to abuse it to get single digits.
