Dunlop Grandtrek AT20
Initial Review: 24,000 miles on tires
July 15, 2012

The day I took my truck home (used with 58K miles on it, but brand new Dunlops on the wheels) I had a feeling I there was something not quite right with the shoes. For the most part, driving in the dry is pretty decent, the tires are fairly quiet, and likely get decent gas mileage due to their size. But thats where my praise stops and the complaining begins. When accelerating from rest easily while making a sharp right hand turn, they aren't sticky enough to prevent slight wheel spin, therefore making you look like a jackass who can't quite drive. Loose gravel makes the truck feel uncontrollable. At first I thought I was having a problem with the Diff, but such was not the case. Additionally, these tires are the WORST in all levels of snow: light and deep. Light snow was the most unnerving as they provided NO grip whatsoever and occassionally will give you the surprise ride for your life if you let them. Granted, I have no traction control but this is my second Tacoma and my '96 didn't display any of the behavior that this truck has. The wear on these tires is absolutely diplorable. I have about 1/3 of the tread left and I've only driven 24K miles on them. Terrible. Absolutely terrible. Finally, the nail in the coffin came when I drove down to a farm where it was mainly grass and gravel to drive on, and somehow managed to puncture the corner between the sidewall and the tread pattern with what appeared to be a large rock. This farm was nowhere NEAR extreme with regards to terrain and having cars consistently driven on the property and not had a failure just makes it more embarrassing for these dunlops. I'm sorry, I will never buy these again and best of luck to anyone who is unfortunate enough to inherit a truck with them preinstalled.
