The tires are so defective that not only can they not be used, but even the car will not stand on them for more than a few hours, and at the same time the store refuses to fix the matter swiftly. In summary, the car is not running, time and money have been spent, the tires are so defective that not only can they not be used, but even the car will not stand on them for more than a few hours. To be honest, I have no idea which scenario is more problematic: having issues with tires or having issues with a business; nonetheless, both scenarios include one issue that is more severe than the other.
