Tires are crucial for safety and performance when buying a vehicle, especially used cars.Proper tires ensure traction, braking efficiency, and fuel economy.Tire safety checks are essential before finalizing a car purchase to avoid risks and unforeseen expenses.Key checks include assessing tread depth, tire pressure, alignment, balance, age, and visible damage.Monitor tread depth using the 'penny test' to ensure safe levels for grip and braking.Maintain proper tire inflation to prevent handling issues, wear, and fuel inefficiency.Uneven tread wear and vibrations while driving can indicate alignment and balance problems.Inspect the sidewalls for cracks, cuts, bulges, and other damage that can compromise tire integrity.Be cautious of wear patterns that may reveal underlying vehicle issues affecting safety and performance.Professional inspections before purchase can reveal hidden tire issues and help with negotiation.
