Tire Pressure Monitor Caps

Description

These Tire Pressure Monitor Caps make it easy to check your tire pressure at a glance. The clear sight glass changes color depending on inflation: green means your pressure is correct, a mix of green and red shows the tire is about 10% low, and full red signals it’s under-inflated by 25% or more. Please note, this device only monitors under-inflation and does not detect over-inflated tires.

                 
• Full green indicates the pressure is correct
• Partial green/red indicates that the tire is under-inflated by as little as 10%
• Full red indicates that the tire is under-inflated by 25%
Important: This device ONLY check your tire UNDER pressure, it does not check your tire OVER inflated.
