Purchased car new with dunlop sp sport 5000M tire size 225/55/17 95H. At 40mph and higher, start hearing a wobble/deep growling noise. Took to dealer and was told the tires are cupped / not worn evenly. The tires have been rotated with each oil change and the car has not been in a accident. Was told I needed new tires, of course there are not under any warranty.

From driving through snow (with newer tires), the wheels became hot enough to be literally on fire and glowing red. Dealer says the E.T.C. malfunctioned but Hyundai refuses responsibility.

Continental conti pro contact tire defect. Tire size: 235/45/19 95V. Bought new from dealer 2013 Genesis rspec with conti pro contact tires. A bubble on the sidewall of the tire formed and the tire deflated Oct 7, 2013. New tires and new car purchased July 22, 2013 and only had 2340 miles on the car/tires when the defective bubble occurred. There was no impacts or road hazards to cause the defective bubble on the sidewall. The sidewall bubble area was mushy versus rigid/firm as the rest of the sidewall. Took car to dealer, and they said I would have to pay for a new tire while Continental tire would assess the defect sidewall bubble. I searched the NHTSA.gov data base and found that there are 39 complaints against the conti pro contact tires for sidewall bubble defects. I checked for any complaints for sidewall bubbles on Continental extreme contact tires and there are none. Thus this appears to be a common defect only on the conti pro contact tires. I am hoping Continental will replace the tire due to this defect. According the number (39) of complaints against the conti pro contact tire there is a common defect that doesn't occur with their other line of tires (extreme contact and others continentals) that I have owned on other cars with no issues.
