BENDIX BW2958 manual Temperature Compensation, Alerts, Guard Against Blowouts

Information from the road is available wirelessly to your back office.

And for even more convenience, the same SmarTire TPMS data can be relayed wirelessly to fleet operators and accessible via SafetyDirect®, a user-friendly Web portal available from Bendix. With tire-related data flowing between drivers, technicians and management, your fleet tire management program can help you more accurately manage tire pressures daily, further enhancing your fleet’s operating efficiency. In fact, fleets that use the SmarTire TPMS system report a 2% increase in fuel economy per vehicle plus a significant increase in tire carcass and tread life.

Temperature Compensation

Since the SmarTire® TPMS system sensors are mounted inside the pressure vessel of the tire, they directly measure the contained pressure and the temperature of each tire. This direct temperature measurement allows the SmarTire system to adjust the first level alert to compensate for increased tire temperature as a result of driving the vehicle.

The SmarTire system displays actual tire pressure and temperature for each wheel location, along with a deviation value that shows the amount of over- or under-inflation based on each tire’s cold inflation pressure (CIP). This value represents a tire’s deviation from current target pressure, compensated for tire temperature, an important feature because tire pressure rises when a tire’s temperature increases from use or outside conditions. As a result, drivers and fleets can accurately maintain tire pressures anytime – whether a truck has been sitting idle or has been driving for hundreds of miles.

Alerts

Three SmarTire TPMS system alerts help drivers, and technicians keep tires in top operating condition.

•The Pressure Deviation Alert – unique to Bendix … is the first warning of an under-inflated tire. If a tire deviates 15% (pressure compensated) from its proper inflation pressure, the driver is alerted to the condition by a warning light and an optional audible alarm.

•The Critical Low Pressure Alert … is the second warning of an under- inflated tire. It warns the driver when a tire's pressure falls 20% below the cold inflation pressure. This visual and audible warning is intended to alert the driver to a critical tire condition and the need to take immediate action.

•The High Temperature Alert … is the third system-generated notification. It warns the driver when a tire's temperature exceeds 185°F (85°C). The SmarTire in-cab display will show both the actual temperature, and which tire is experiencing the problem, along with an orange LED and high temperature icon.

*All alerts are customizable by the fleet using the gauge.

Guard Against Blowouts

Our innovative temperature compensation feature also allows the system to provide earlier warnings of a potentially severe tire problem. Especially critical for trailers, the SmarTire TPMS high- temperature warning alerts drivers to possible thermal issues, such as an overheated wheel-end due to a bearing or brake issue.

THE NUMBERS TELL IT ALL… UNDER-INFLATED TIRES ADD REAL COSTS TO YOUR FLEET

üOnly 44% of all truck tires are within 5 psi of their target inflation

üNearly 90% of all tire failures are from under-inflation

üAlmost 50% of all emergency roadside assistance calls are a result of tire failure

Running on 20% under-inflated tires cuts:

ncarcass life by 30%;

ntread life by 25%; and

nfuel mileage by 2%, increasing your fuel spend by up to $1,000 per year for a single truck

But checking tires can also be expensive

•Time to check tires on a tractor-trailer ≈ 30 minutes

•Hours per year for each tractor-trailer ≈ 42 hours

•The average hourly rate of a technician ≈ $60

•The cost to check tires annually/tractor-trailer ≈ $2,500

With just the labor savings alone, SmarTire® TPMS by Bendix can pay for itself in just eight months!
