If an auto dealer replaces a tire that blew out on car purchased from him 3 weeks ago is he implying warranty the rest of tires considering it still under 336 factory warranty?

Replacing a blown out tire as a one-time courtesy under the factory warranty does not imply an extended warranty for the remaining tires. The terms of the factory warranty are determined by the manufacturer and typically cover specific components or systems for a certain period or mileage, and not the entire vehicle. It's important to review the specific terms of the warranty provided by the manufacturer or the dealership to understand the coverage and limitations.
