Real-Time Tire Warnings and Alerts

At the push of a button, SmartWave will provide the driver with real-time tire status information for each wheel on their vehicle. For every moment in between, SmartWave has 3 automated tire alerts to instantly warn the driver of an under-inflated tire before it becomes dangerous.

Pressure Deviation Alert

Critical Low Pressure Alert

The Pressure Deviation Alert is the first warning of an under-inflated tire. If a tire deviates 10% from its "proper" inflation pressure, the driver is alerted to the condition by a warning light and an audible alarm (optional). SmartWave calculates a tire's "proper" inflation pressure by first mathematically calculating the amount of pressure that is supposed to be in the tire based on its operating temperature and its cold inflation pressure setting, and then comparing this calculated value to the actual, measured pressure value of the tire. The pressure deviation value that is displayed is the difference between the actual pressure and the calculated "correct" pressure. This temperature compensation calculation enables SmartWave TPMS to provide pressure deviation values and alerts even when a tire is hot.

The default setting triggers the pressure deviation alert when a tire is 10% under or over inflated. This setting can be customized by the user. The alert can also be customized to be a fixed pressure alert rather than a temperature compensated alert. The units of measure can also be customized to PSI, bar, or kPa.

Critical Low Pressure Alert

Critical Low Pressure Alert

The Critical Low Pressure Alert is the second warning of an under-inflated tire. It warns the driver when a tire's pressure falls 15% below the programmed cold inflation pressure (CIP) value. This visual and audible (optional) warning is intended to alert the driver to a critical tire condition in order for them to take immediate precautions.

Unlike the Pressure Deviation Alert, the default setting for the Critical Low Pressure Alert does not include the temperature compensation calculation. As such, if a tire's pressure falls below the default setting, the tire is critically under-inflated and should be addressed immediately.

Like the Pressure Deviation Alert, the default settings for the Critical Low Pressure Alert can be customized by the user. The alert can also be set to be temperature compensated.

High Temperature Alert

Critical Low Pressure Alert

The High Temperature Alert warns the driver when a tire's temperature exceeds 195°F (90°C). High tire temperatures are typically caused by under-inflation and the SmartWave system will usually provide a Pressure Deviation Alert and a Critical Low Pressure Alert well in advance of a High Temperature Alert. If triggered on its own, the High Temperature Alert can be an indication of an alternative problem such as a dragging brake or a bearing failure. Like the other two alerts, the default High Temperature Alert setting can be customized by the user.
