Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

ON MARCH 12, 2009 I BOUGHT 8 SUMITOMO 255/70R22.5 MODEL #ST727 TIRES FOR MY COMMERCIAL TRUCK. APROX. 50K MILES OF USE ONE OF THE TIRES ARE CRACKING FROM THE TOP OF THE TIRE GOING DOWN THE SIDE WALL. I WAS TOLD BY THE RETAILER THAT THE TIRE DID NOT SHOW ANY SIGNS OF IMPACT AND THAT IT IS ONLY A STRESS CRACK AND NOT A DEFECT. *TR
