I have only done 20,000 km /12500 mile so far,probably half of it on motorways, and I have two sets of wheels, one on original summer blue earths, and a set on Goodyear vector all seasons. I intended to record exact mileage done on each set but I lost count. But its about 10,000 km, 6000 miles on each set. The blue earths have some wear on the fronts, but evenly spread and not excessive,They should last at least 20,000 miles /30,000 km if left on the front or longer if I swop fronts to rears.
Less wear on the all seasons, and they will probably last even longer. It may surprise some that despite their more open tread pattern All season tyres often perform well for tread wear mileage.
Some excess wear is probably due to the extra torque. But you dont always have to use it all
I can understand Wonder's point about roundabouts. I do tend to use the extra torque ,with no need to change gear on the roundabout ,to merge with other traffic in a more ' positive and assertive' way,(ie sometimes a bit faster ,taking opportunities I may not have taken in a less responsive manual car.
) This may increase tyre wear slightly not just for accelerating, but when cornering.
Edit - added after Kremmens next comment. On a previous car my daily commute involved a tight U turn. Over time this resulted in increased tread wear on the outer edge of the nearside front tyre.
