Just had to replace the 2 fronts on my 2010 EX. Were fitted with Dunlops, the OSF was just beginning to go below the indicators and the grooves were cracked, NSF marginally more tread.
Replaced both fronts with Dunlops, tracking and insurance £204 all in.
Fairly happy at 31,000 miles before replacement so I should be getting rid of the car before they wear out again...backs still on about 5 mm.
