Tire temp uneven.

This has come up before and seems to be common. My 2012 does exactly this.

 

I recall being surprised that the fronts run warmer even without getting into the brakes. After all the rear is where the power train is so it should run warmer right? Evidently the radiator heat is spread very efficiently to the front wheel area.

 

Manually take each tire pressure and adjust each tire to its desired level. Then RESET the TPMS.

Tires with temps over 100F perform well. Cold tires beware.

I find the trunk space of the Speciale in the front warmer than the F430 as well as other mid engine supercars too.
Anyone experienced the same?

 

A thing to notice is that public roads curve, to allow for drainage. This means that the left and right side tyres are loaded differently. I've seen this trend on my cars, and when I've been to a track with a flat surface, the issue has been much less profound, if there at all. Also, you sit in that side, so you add weight to that tyre. Don't know how big you are?
I don't trust TPM systems 100%. I check my tyres with a good calibrated manometer, you should do the same. If you're unsure about the alignment, just have it checked.

All this being said, I've never had a car with a monitoring system where the tyres warmend up exactly the same. There are a lot of variables. I know people who corner weigh their cars, and use that information to adjust pressure. That could be an option too.

Enjoy in good health.

Best.

 

Does anyone have a good answer for how it's measuring the temps? I've looked through service manual and I can't find a mention anywhere of temp sensors. I spoke with my local service tech and he feels very strongly that there are no sensors and it's a calculated value based on g-loads and steering inputs and not an actual measurement.

I've looked and have not found any sensors (IR or laser) to read tire temps. Only other possibility is it's built in to the pressure sensors, but then it would only be reading the inner air temp of the tire.

Google search has come up with nothing.

 

What about brake temperature? Are there sensors?

 

my Italia has the same temperature gradient across the front. Seems to be normal. Is it possible the temperature sensor is combined in the TPMS sensor?

 

All TPMS sensors are capable of measuring pressure, temp and usually rotational acceleration status. Depending which system F bought in determines its functionality, but most all provide actual temp measurements, albeit delayed by the sensor's measuring frequency.

 

TPMS measures the temp. When parked in the sun for a while, the tires on the sunny side show a higher temperature than the shady side. Sometimes 10-15F difference.

In the morning before drivng the TPMS shows a temp within a degree or two of the temp reading in the garage. After driving the temperatures climb. the fronts get warmer faster and remain warmer.

top temps after a few miles (5-10) show front temps of ~110F front and ~95F for rears. This is for normal ambient temps of at least 60F.

The reason the drivers side front heats up faster is the cooling fan pushes the hot radiator air in the wheel well and causes the tire to heat up faster. Let your car idle until the fan comes on and you will feel it

 

My Speciale was also warmer in the front driver side tire. The official explanation was that the driver side front was loaded more than the passenger front when in a single driver scenario. The rear tires do stay a bit cooler than the front.

also of note though, in my 12C, the front 2 wheels stayed exactly the same temperature no matter if I have a passenger or not, but they do get a bit warmer than the rear.

 

This is the explanation for a difference of about 5 to 7 degrees F. The sun and uneven loads can make a difference of another 1 or 2 degrees.
