I filed a complaint ON1/16/2014 of my brand new Ford Flex having a issues with hankook tires being in the red at 17,000 I felt these tires were unsafe and unacceptable claim number [xxx]. on 1/16/2015 I went into dealer for inspection sticker and oil change and was told at 39,000 the steel was showing on my tires and it wouldn't pass inspection. This is unacceptable for a tire and unsafe. Hankook warranty on these tires outside of Ford is 60,000. Steel should not be showing at 39000 miles hence tires had to be replaced.

We have 16,980 miles on the vehicle, and bought the vehicle 1 year and 3 months ago brand new. The tires are hankook H426, 255/45/R20. Dot 5mnb pdlh 4112, 4112, 4112, and2012. The car steers straight as an arrow. The Ford dealer has verified all is well with the suspension and steering. We have found all four tires, are starting to peel apart on the inner and outer row of treads only. To date, there are 100 peel backs and as many holes. All of the un-wrappings are approximately 10mm in diameter, 1-2mm deep, shaped like a tear drop. Some of the points of the teardrops face to the front of the tire rotation and others face directly to the rear of the tire rotation. The rubber is peeled back at the point of the teardrop, and after a few days, the teardrop is torn off, leaving a tear dropped shaped hole 1-2mm deep. This is a family vehicle, with three small kids. We do not tow with the car and we keep the tire pressure @ 37 psig. We drive the speed limit everywhere. We have never been off road, occasionally parking in a gravel parking lot, at slow speeds. The Ford dealer has contacted hankook, and they will not do anything about this issue. These tires are failing, a safety hazard, and hankook should replace all 4 of these tires, now, for free.

I leased a 2013 Ford Flex, limited, AWD, with the eco-boost engine upgrade. My wife slid into the lawn making a turn on our driveway into the garage due to the lack of grip in snow and ice of the hankook optiomo H426 tires. I paid extra for the 2)' wheel and tire upgrade. The tires are listed on the window sticker as all season tires. In checking several of the rating services, including tire rack, these tires are considered unsatisfactory in winter driving conditions and marginal for hydroplaning. In essence, hankook has produced a tire that cannot do what it is supposed to do. One purchases a large AWD SUV, with all-season tires, to be able to drive in all types of weather. I believe that hankook has produced a product that will eventually cause an accident. These tires are so bad, that they should be recalled. I purchased a $50,000 vehicle that was sold to me as a year round car, without the need to change tires for snow. The rating on the hankooks in the snow is about the same as tires sold as summer tires, not all-seasons. Neither Ford or hankook will do anything, as they do not see a defect. The defect is the production by hankook and the selection by Ford. I would like to get these tires off my vehicle asap before something happens. I should not have to spend $1000 out of pocket due to a product that does not do what it says it will do.
