I must admit that I found the wear on the Dunlop SP 2030s was really bad on my 2013 Mk 2. At 12,500 miles the fronts were down to just over 3 mm.
On my first Mk3 the Michelin Energy Savers on the front had 6 mm after 20,000 miles so I reckon they would have done around 40,000.
I've got 2030s on the new car but, at current mileages, it will be 4 years plus before I reach 12,000 miles!
