GMC Terrain tires consistently losing air despite being brand new on GMC Terrain

Some GMC Terrain owners report experiencing consistent air loss in their brand new tires due to various issues. Common problems include valve stem issues that may arise during installation or servicing, as well as faulty valve stems that contribute to air loss. Additionally, some owners find that damaged rims, such as those with cracks, can lead to tire pressure loss. Improper sealing of the new tires can also result in leaks, while gas leaks may occasionally be a factor. Furthermore, temperature changes can cause normal pressure fluctuations, with tires losing approximately 1 PSI for every 10°F drop. Lastly, natural permeation can lead to gradual air escape through the tire walls over time. To address these concerns, it is advisable for owners to have valve stems checked, ensure proper sealing, and inspect for any rim damage.
