Summary:
Tires are an inevitable expense for vehicle owners, much like death and taxes. Understanding how long tires last and how to maximize their lifespan is crucial. Tires for passenger cars, light trucks, and SUVs generally fall into three categories: summer, snow/winter, and all-weather. Light-truck (LT) rated tires are also available for pickups and SUVs. Summer and LT tires usually last longer due to harder rubber compounds, with a typical tread-wear rating between 50,000 and 140,000 kilometers. However, factors like driving habits, road conditions, and climate can significantly impact this range.
Driving habits are a major factor in tire wear. Aggressive driving, such as rapid acceleration, hard cornering, and frequent heavy braking, can significantly reduce tire lifespan. Heavy cargo and towing also contribute to faster wear. To get the most out of your tires, consider their tread-wear rating when purchasing, and aim for a higher rating if your driving style is demanding.
Road conditions, such as potholes and rough surfaces, can lead to faster tread wear and potential damage. To minimize impact damage, drive carefully, especially over rough roads.
Climate and environmental factors also play a role. Exposure to sunlight and hot air can cause tires to age and develop cracks. Small cracks might not affect performance, but deep cracks exposing the support cords indicate that the tire should be replaced.
Proper tire maintenance includes regular pressure checks, rotations every 10,000-12,000 kilometers, and ensuring proper wheel alignment. Misaligned wheels or worn suspension components can cause uneven wear. Tires should ideally be replaced in sets of four, especially for all-wheel-drive vehicles, to avoid drivetrain issues. Tire warranties often have conditions and may only cover a prorated amount, with installation and balancing typically not included.
