Pump up your tire to the correct pressure, replace your valve cap with a tire pressure monitor and be warned when tire pressure drops.
You get four tire pressure monitors.
When put in place you see mainly green showing all is OK.
If your tire pressure drops by 2psi or more a red warning indicator is exposed like a warning flag.
This means that you can quickly check by glancing whether tire pressure is OK, and unlike using a tire pressure gauge no pressure is lost and it is easy.
Tire pressures from 20-42 psi are monitored taking in most normal vehicles from motor cycles through cars to small vans.
