We were heading out on vacation from akron, Ohio when the dashboard low air pressure tire light came on during our trip. We exited off at the next exit for gas and to add air to the rear tire. We heard air leaking from the tire tread area and had to go to a local repair shop in sissonville, wv for the repair. The repair shop reported that we had tread separation and that the steel belt made a hole in the tire. He changed our tire with a used one to get us to our destination in North Carolina. In boone N.C. we had our tires looked at and they showed us the we had another tire with a 4 inch slit in the tread area and was cupped ( a broken belt); this also was the rear tire. They remaining two tires showed signs of tire separation. All four (4) tires were replaced with new ones. Our vehicle is a all wheel drive 2011 Hyundai tuscon.

2 of my 4 kumho tires went flat at the same time with tread coming off of one. They had 25,433 miles on them. This appears suspicious and dangerous. I would like to be re-imbursed for the 4 replacement tires I had to buy as my vehicle is an all wheel drive vehicle.

I had both rear tires go flat within 10 minutes and one of the treads came off. My concern is the safety of the kumho tires and not getting any answers from their company. Both tires went flat.
