What should you use to adjust tire pressure?

Adjusting tire pressure requires inflating or deflating a tire to reach the manufacturer's recommended pressure. The best tools for achieving this are an air compressor or a hand pump. An air compressor, typically found at service stations or owned for personal use, can rapidly inflate tires by delivering compressed air directly into the valve stem, making the process quick and efficient. A hand pump is also an option for manual inflation, although it may take more time and effort compared to an air compressor.

Utilizing a tire gauge is crucial before and after making adjustments to ensure the correct pressure is achieved, but it does not perform the actual inflation or deflation. Similarly, while a nitrogen tank could theoretically be used to fill tires with nitrogen instead of air, it's less common and not a practical choice for everyday tire adjustments. A foot pump can be employed as well, but it generally requires more labor than an air compressor, making it less convenient.
