How Often Should Drivers Check Tyre Pressure? Why Pros Recommend Weekly Tests
Most UK car owners don't realise their tyres are silently losing air every single day. In fact, TyreSafe has found that more than half of the UK's car tyres are below the suggested threshold. These numbers matter, experts say. This gradual pressure loss creates a dangerous gap between what drivers think their tyres need and what they actually require for safe motoring. Understanding this natural phenomenon (and taking proactive steps to address it) can save money, prevent accidents, and extend tyre life significantly. Tyres Lose 1-2 PSI Every Month Through Natural Permeation Even brand-new tyres with perfect seals lose air continuously through a process called permeation. The rubber compound, despite appearing solid, contains microscopic pores that allow air molecules to escape gradually. This natural process results in a consistent pressure drop of approximately 1-2 PSI per month, regardless of driving habits or road conditions. The permeation rate varies slightly based on t...
