Medical Definition of adhesive. 1: an adhesive substance; especially : a substance (as glue, starch, paste, or mucilage) that bonds two materials together by adhering to the surface of each.
The sensors physically measure the tire pressure in each tire and report it to the vehicle's instrument cluster or a corresponding monitor. Some units also measure and alert temperatures of the tire as well. These systems can identify under-inflation in any combination, be it one tire or all, simultaneously.
To get the most relevant tire pressure, you need to check when the tires are cool, just before you head out for the day, or hours after your vehicle has been idle. Tires that have been used recently will have a higher pressure due to the heat from use.1  Get a cheap tire pressure gauge from any local auto parts store or hardware store. 2  EVERYONE who owns a vehicle should have one. 3  Screw the cap off of your tire. 4  Apply the tire pressure gauge to get the tire pressure. If they do, go elsewhere. 2  Inflate your tires to the recommended levels. 3  I always go 2-3 PSI over because I have driven to fill the tires and they are hot from use. 4  If you go too much over, deflate the tires by tilting the valve stem until you hear the sound of air escaping the tire.
