What is the recommended mileage for tire replacement?

The recommended mileage for tire replacement can vary depending on several factors, including the type of tire, driving conditions, and vehicle usage. Generally, a common guideline is to consider replacing tires every six years, even if the tread seems sufficient, as materials can degrade over time. For many tires, a tread wear of 2/32 of an inch is considered the minimum acceptable depth. Additionally, some tire manufacturers recommend replacing tires after about 40,000 to 70,000 miles, but this can differ significantly based on the tire model and quality. It is also important to regularly inspect tires for signs of uneven wear, bulges, or significant damage. Checking the manufacturer's specifications on the Firestone website or the product details for specific tires can provide more precise recommendations. Always prioritize safety and performance when considering tire replacement.
