For SUV models, a tyre pressure of 38 PSI (approximately 2.62 bar) is on the high side, but a comprehensive assessment should be made based on the specific model and tyre type. The recommended pressure for standard SUV tyres typically ranges from 2.2 to 2.5 bar (32-36 PSI), while reinforced tyres can withstand 2.8 to 2.9 bar (40-42 PSI). However, the maximum safety limit should not exceed 3.5 bar (51 PSI). Excessive pressure may cause abnormal wear in the central tread pattern, reduced traction, and potential steering wheel vibration or pulling. If 38 PSI exceeds the manufacturer's recommendation by more than 10%, adjust it to the standard range by releasing air. Check tyre pressure monthly during routine maintenance, with special attention before long trips. In summer, allow 0.1 to 0.2 bar for thermal expansion; in winter, consider increasing pressure by 0.2 bar to compensate for rubber stiffening. Proper tyre pressure enhances driving safety, improves fuel efficiency, and extends tyre service life.
