🧠 Explanation:
Pounds per square inch (psi) measures tire air pressure, ensuring vehicle safety and efficiency. Typically 30–35 psi for cars, correct pressure enhances handling, fuel economy, and tire durability. Incorrect levels risk blowouts or uneven wear, compromising safety. Mechanics use gauges to monitor psi, vital for traction and stability. Widely used in the U.S. automotive industry, psi reflects practical engineering needs. This measurement’s role in vehicle maintenance underscores its importance in daily life, supporting safe driving and economic benefits by prolonging tire life and optimizing performance across diverse road conditions.
