Replaced Dunlop OEM tires at 50651 miles in Nov. 2007. Bought the Geolanders because reviews said that the ride, traction, handling, and tire wear were excellent. I have not had that experience. My Tacoma spins the tires most of the time I get heavy footed on a start and every time I accelerate quickly on wet pavement and snow. The ride and noise level have not been any better than the Dunlops. The most discouraging finding has been wear. The tread on all four of my tires is between 2/32 and 4/32 and I have only put 28200 miles on these tires. I will see how they perform this winter. I may have to replace them before I get to 35K.
