225 40R 19 89Y I was traveling at 50 MPH and hit a man cover in the road and several days after I noticed that the tire was separated. I have sent an email to the manufacture and was told to take the car to one of the tire distributor, I did and have the tire inspected. I am having problem with the manufacture having warranty the tire. I had less that 6000 miles on the tire.
