Dunlop Grandtrek AT20
Initial Review: 6,000 miles on tires
March 17, 2013

Got these tires new on a new 2011 Toyota 4Runner. Bought the 4Runner for the wife in September. I didn't drive it till about 5500 miles in the wet and I never got to try them in snow as I removed them. On the way to work one day when I had the 4Runner it was raining. I was at the speed limit 40mph or less in a medium rain shower and I noticed the front wheels lost steering. I slowed and they came off the hydroplane restoring steering. On the way home that night after work it was raining again and they hydroplaned all way home at the speed limits of 40 and 45. In the dry they seemed adequate but not good, but after the hydroplaning they were removed and replaced with Continental CrossContact LX20 with EcoPlus Technology. The Dunlops saw 6000 miles till I found out how bad they are and were removed. I couldn't believe they came on the new vehicle. If you live in the desert where it's dry they might be ok but if you drive in the wet you don't want these tires.
