Like I said, after almost 20,000 miles on my 07 6 spd XF.....the Achilles (on the front) still have slightly deeper tread depth (about 6/32nds) left than the OEM fronts on my wife's 08 automatic XF & her car only has 10,400 miles on it.

Both cars are wearing evenly across their tires. I've had them up to 120 mph & driven thru 6-8 in snows....I'm still alive!!
