I have Yokahama Parada Spec X on My 2011 D also, Love them, Had them also on my Chev. Truck, Nice ride and Handling!!

Original kuhmo tires wore out at 25000. Replaced with Goodyear eagle rsa's. They are worn out at about 15,000. These are on a 2012 rt. 265/50/20. Purchased some hankooks and having them put on tomorrow. Hopefully better tread life as the rsa's had no wear warranty.

I'll be putting on my third set of tires soon as i'm at 103,000 miles on my '11 Express DD, i plan to use the Michelins as they have been so smooth and fuel economy for a AWD #5,000 vehicle (21 mpg) seems pretty good and I drive too many miles to live with something inferior to that. We had 150 inches of snow last year and temps in the teens most of the winter and i never got stuck or did i feel i did not have good control with the Lattitudes.
