8 PCS Car Tire Pressure Monitor Valve Stem Caps, 2.4Bar 36PSI Tire Valve Stem Cap Cover, Car Tire Pressure Monitor Sensor Indicator with 3-Color Eye Alert, Universal for Most Cars
3-Color Pressure Monitoring:These tire pressure caps feature a 3-color indicator (green/yellow/red) for visual pressure alerts. Green means normal pressure, yellow signals 10% below standard, and red warns of 25% low pressure. Check pressure at a glance to catch issues early, avoid under-inflated tire risks, and boost driving safety.
Quality Material: These tire stem caps are made of sturdy stainless steel, resisting water, wear, and high temperatures—holding up in rain, snow, or sun. With a built-in chrome-plated copper core, they won't break or deform, maintain functionality long-term, and eliminate frequent replacements.
Enhanced Safety Monitoring: These tire pressure gauge caps continuously monitor tire pressure to help prevent premature wear, blowouts, and unsafe driving conditions. They also promote better fuel efficiency and extended tire life by maintaining proper inflation.
Wide Compatibility: Pre-set for optimal performance at 2.4 Bar/36 PSI (the standard pressure for most vehicles: cars, trucks, SUVs, RVs, motorcycles, bicycles), they align with standard valve sizes for a snug, leak-free fit—making them versatile for any vehicle owner.
Easy Installation: These tire air caps install in seconds: remove the old valve cap, clean the valve, then screw these on until snug. Each set includes eight tire valve stem caps—enough for all four wheels plus spares—to monitor pressure consistently across all tires and cover all needs.
