Why are my tires flat in winter?

You may notice that your tires appear to be flat during winter. There is a perfectly good explanation for this. During cold weather, gases will condense. This will cause the pressure inside the tire to drop. In most cases, the pressure level will drop about 1 to 3 psi.

If the needle is below the normal range, it means that the tire is low on air. Another way is to look at the sidewall and see if it is bulging.

Why do tyres lose air pressure?

Tyres lose air pressure as the temperature changes, especially when it suddenly drops. Check your air levels at any time your car is exposed to sudden changes in temperature. While the pressure lost might be minimal, pressure changes can accumulate over time and will compromise handling on roads and corners.
