Is it safe to use tire pressure gauges that are not calibrated?

Using tire pressure gauges that are not calibrated can indeed result in inaccurate readings. Accurate tire pressure is critical for vehicle safety, fuel efficiency, and tire longevity. A properly calibrated gauge will provide reliable tire pressure measurements, ensuring that you can maintain the recommended pressure levels for your tires. If a gauge is not calibrated, its readings may either overestimate or underestimate the true tire pressure, leading to possible under-inflation or over-inflation of tires.

Under-inflated tires can increase tire wear, reduce fuel efficiency, and impair vehicle handling, while over-inflated tires can also lead to uneven wear and a harsher ride. Ensuring the accuracy of your tire pressure gauge is essential for optimal performance and safety on the road, making calibration an important aspect of regular vehicle maintenance.
