TPMS system question

[Bobcatou]

On my Ford OEM TPMS for my trailer,. will they alert me on my main screen if the temperture gets too high or I lose pressure? What is considered too high and I should pull over if not.

Temperature is displayed on the trailer tire info IPC screen but there is no user-configurable max temp set-point or warning relating to tire temperature.

There is a user-configurable set-point for minimum trailer tire pressure; when a trailer tire drops below the minimum pressure you set, you will get a bold warning on your IPC display even when the trailer tire screen is not displayed.

Note. all of this is on the IPC (Instrument Panel Cluster) display in front of your steering wheel, not on the larger 'main' display at the center of your dashboard.

Thanks...I found this information on it. It will tell you if your temperture is too high. It doesn't say what that temperture is to trigger it.

I stand corrected, but really wonder what they consider "too high" temperature?

One might wonder if the temp warning is based on detecting a significant difference on one tire relative to the others, which might not be a bad approach vs some Ford-selected absolute value.

An anomalous value on one tire is what I'm looking for when I scan temperatures, not a particular absolute value.

Obviously, I've never seen a temperature warning, have no idea how one might test that safely.

Well I repacked my bearings a couple months back and am heading out later this week for an extended camping trip down to Utah and area. If I screwed up the repacking, I'll let you know the temp then go out.

From Google AI, take it with appropriate scrutiny. It is dependent on your specific tire temperature rating.

There is no single definitive temperature limit, but a good rule of thumb is to set the tire pressure monitoring system (TPMS) alarm for high temperatures at around 150-160°F (65-71°C) to provide an early warning for potential issues. Tire failure can occur above 195°F, so setting the alarm at a lower temperature gives you time to pull over before catastrophic damage happens due to excessive heat.
Understanding Tire Temperatures
Normal Operation: Under normal conditions, tires can get about 50°F hotter than the ambient temperature.
High-Heat Situations: During highway driving or in hot weather, tire temperatures can rise significantly.
Tire Failure: Tires can start to lose structural strength and become prone to failure at temperatures around 195-200°F (91-93°C).
Inconsistent Temperatures: A key indicator of a problem is when one tire's temperature is significantly higher than the others.
Why Set a Lower Alarm?
Early Warning: A lower alarm setting gives you time to identify a potentially problematic tire and pull over safely before the tire is severely damaged.
Tire-Sensor Difference: The sensor itself is not the tire, and it can be cooled by the wind. The actual tire temperature can be significantly higher than the sensor reading.
Factors to Consider
Tire Manufacturer Specs: Always check your tire manufacturer's recommendations for maximum operating temperatures.
Tire Load and Speed: High speeds and heavy loads increase tire temperatures.
Environmental Factors: Driving on the sunny side of the road can result in hotter tires on that side compared to the shaded side.

A temperature rating of "A" for a tire means it has excellent heat resistance and is expected to perform well at speeds over 115 mph, with a maximum safe operating temperature of up to 249°F (120.5°C), according to Versatyre, trailerwatchdog.com. A is the highest rating, indicating superior heat dissipation and durability under high-speed conditions, as rated in laboratory tests by the manufacturer.
Understanding the A Temperature Rating
Highest Heat Resistance: A "A" rating signifies the best heat resistance among the three ratings (A, B, C).
High-Speed Performance: Tires rated "A" are designed to withstand the heat generated by speeds exceeding 115 mph.
Manufacturer-Assigned: These ratings are assigned by tire manufacturers based on laboratory tests and are not set by the DOT or NHTSA.
General Tire Temperature Safety
Beyond 195°F (90.5°C): Tire temperature can impact tire life, with tread wear accelerating beyond this point.
Around 250°F (121°C): At this temperature, tires can begin to lose structural strength and are at risk of blowout.
Stop If Approaching Danger: If a tire's temperature gets close to 200°F (93°C) or higher, you should stop as soon as it is safe to do so, allowing the tires to cool down.
Factors Affecting Tire Temperature
Load Weight: Heavier loads increase stress and friction, leading to higher temperatures.
Tire Pressure: Under-inflated tires create more rolling resistance, causing them to heat up.
Speed: Higher speeds result in increased friction and heat.
Ambient Temperature: Hot weather contributes to increased tire heat.

Maybe half way between normal operating temp and the limit.
