Underinflating tires increases rolling resistance. This forces the engine to work harder and consume more gas. A study by Oak Ridge National Laboratory found that a 25% drop from recommended pressure can reduce your car’s efficiency by up to 3%, while a 50% reduction could cut it by as much as 10%. In winter, colder temperatures cause tires to lose one or two pounds per square inch (PSI) for every ten-degree Fahrenheit decrease.

Checking tire pressure regularly is essential. Manufacturers recommend specific pressures found on the driver’s side door jamb and in owner manuals. Never inflate them to max PSI marked on the tire itself, as this isn’t the suggested level but rather a safety limit.

Overinflating tires slightly above recommended levels might seem like an easy way to boost fuel economy. However, tests show that increasing pressure by 40% results in only about a 0.12% improvement—hardly worth risking tire failure and handling instability for such small gains.

Maintaining optimal tire pressure isn’t just about saving money on gas; it’s also crucial for ensuring safe driving conditions and minimizing wear and tear on your vehicle.

The EPA’s proposal follows a series of actions by Sean Duffy since he took office. For instance, his reinterpretation of CAFE standards claims the department lacks authority over fuel economy regulation—a stance critics argue is false and could undermine efforts to reduce pollution and save money on gas.

Automakers stand to benefit from these changes as they won’t face fines for past non-compliance with stricter fuel efficiency rules. This shift means car companies like Stellantis will avoid penalties but consumers may see higher fuel prices, which is particularly tough during an ongoing affordability crisis fueled by inflation and tariffs on imported goods.

Consumer advocates worry that rolling back these standards could lead to increased air pollution and higher energy costs for families already struggling financially. The proposed changes aim to make it harder to enforce stricter future regulations, potentially setting a precedent for laxer oversight of vehicle emissions in the long term.

This proposal highlights a clash between regulatory goals for efficiency and industry preferences for flexibility. As families face tough choices on how to manage their budgets amid rising costs, such decisions have real-world implications that touch everyone’s pocketbooks.

The proposed rollback would lower fuel economy requirements over the next decade. The move aims to soften penalties on automakers, allowing them to produce less efficient vehicles without facing fines from 2022 onwards.

Automakers like Stellantis have benefited from these changes with savings in millions of dollars. However, analysts warn that this could lead to higher fuel costs for consumers and increased pollution levels.

The Biden administration’s original rule aimed at reducing demand for fossil fuels by requiring automakers to produce more efficient vehicles. Critics argue the rollback undermines efforts to combat climate change while proponents say it will boost car manufacturing jobs in the U.S.

The proposed changes reflect ongoing debates about balancing economic interests against environmental goals. Critics argue the rollback will hurt consumers financially while supporters claim it benefits domestic car manufacturers by reducing regulatory burdens.
