All four tires on my 2004 Cadillac SRX, Goodyear Eagles, cupped within the first 5,000 miles. They made horrible noise. I could not get anyone to listen to me until the car had 24,000 miles on it and rode and sounded like a Sherman Tank. The battery had to be replaced. I also had the tire monitor repaired three times and the door seal reaplaced.
The exterior design.
Upgrade the tires and provide much more noise insulation.
