What is the purpose of a tire chuck?

A tire chuck is a device designed specifically to securely attach to the valve stem of a tire, allowing for the inflation of the tire. Its primary function is to enable air to flow from an air compressor or inflator into the tire, which increases the tire's air pressure. This is essential for maintaining proper tire function, improving vehicle performance, and ensuring safety while driving.

Understanding the context of the other options enhances the clarity of this information. Measuring tread depth pertains to assessing tire wear, which is unrelated to the inflation process that a tire chuck facilitates. Checking alignment refers to ensuring the vehicle’s wheels are appropriately positioned relative to each other, which is a different maintenance concern. Repairing punctures involves fixing holes in tires, which may require different tools and techniques entirely. Hence, the function of a tire chuck aligns distinctly with tire inflation, affirming its role in maintaining optimal tire conditions.
