Tyre temperature related to tyre pressure

Before posting this topic I saw the similar issue also posted in the PC section:
http://www.assettocorsa.net/forum/index.php?threads/tyre-pressure-and-temperature-corelation.33303/

It looks like this issue is still present on PS4 (and probably also on XB1).
I did some testing with different tyre pressures and it seems to have little or no effect on tyre temperature. I tested this with a friend on our own PS4 with our own copy of the game. KTM X-bow was tested during practise at Imola. At standard (25 psi) tyre pressure, the tyre temperature is around 75-80 degrees Celsius after a few laps driving. Ambient temperature was at 26 degrees C. I wanted the temperature to become higher and adjusted the pressure to 18 psi at all tyres. I had little to no effect on the tyre temperature while you might expect a higher temperature if you lower the pressure (correct me if I'm wrong, or if are other parameters are involved).
After this I drove the Corvette C7r racecar to Imola and after lowering the standard tyrepressure to 17 psi, only the frontleft tyre was around 100 degrees C and the other tyres stuck around 75-80 degrees C. This seems weird, also because Imola is a circuit that's going counterclockwise, so you expect the right tyres to be warmer than the left ones.
My friend expirienced practically the same issues. He also performed a burnout in a BMW Z4 GT3 and thereby heating his rear tyres to around 300 degrees C, so that seems properly simulated.

Someone who has the same struggles with this issue? To me the correlation between tyre pressure and tyre temperature just does not seems to be correct.

 

There seems to be no relationship between pressure and temperature in game right now. Pressure doesn't seem to change at all from what it has been set to.

Switch tyre blankets off note that the hot pressure is lower than the cold pressure.

Hit the track do some laps, tyres heat, hot pressure does not change!?

If this is a physics thing or a problem with the information being shown in the setup screen I do not know! Either way I am a little blind as to what is going on with the dirty black things that connect the car to the road.

Camber also seems to have more of an influence on temperatures than pressure right now, but I am not sure if the inside, middle and outside temperatures are being displayed correctly either! I can feel the wheel become heavier with a camber change so it is doing something.

Have to grab some screens and or make a clip I guess...

 

Would like to at that wile performing the burnout (straight line) the rear tyre with lower pressure got lower temperature in comparison with the other rear tyre with higher pressure. That's strange. Because lower pressure results in more friction, and so, causes more temperature. And that's not the data I received.

Drove some laps with lowest pressure and some laps with maximum pressure. I did feel some difference between both sessions. With maximum pressure I feel more sliding in corners (like it should).

 

That would just be a pit menu issue possibly its just showing start pressures and temps rather then last known from last session. In PC version you can see live temps and pressures and these are critical to car setup, I dont have a console version but is there any app that shows you tyre temps or pressures on the hud for your version.

 

We only have the information from the screen in the setup menu's. No other information is available at this time. Hopefully we get something at some point I'd like to know a little information about what the tyres are doing!

The hot pressures only relate to tyre blanket temps then?

 

Some of the GT-cars(Nissan GT-R GT3 and Corvette C7R for example) have live tyre pressure onboard.

 

Am I doing something wrong or is the tyre temperature since patch 1.03 not available at all? When I enter the pits after some laps during practise, the tyre temps are 'n/a'.
I think one of the basic things to start with making a car setup is to decide the right tyre pressure to assure the tyre temps are within a good range. Now this seems to be impossible.

 

I seem to remember that tyre wear needs to be on to see temperatures.

 

You are right, my mistake! Altough tyre pressure still seems to have no influence on the tyre temps. This simply cannot be possible and seems to be bugged...

 

I noticed that the tire wear is always zero when getting into the pits, even after a 10 lap race on soft tires. I've seen graining at 17%, blistering at 6%, with tire wear 0%.

Another thing I noticed on a practice session (Lotus two eleven,):
- drive some laps on Imola, back to pits, tire temps around 57 degrees.
- 1 psi change to tire pressures, continue driving some laps, tire temps around 60 degrees.
- reduced fuel load, reduce TC, some more laps, back to pits on near empty tank, tire temps are now 37 degrees ?!?!?.

In settings tire wear set to "on", and mechanical damage to 100%, no tire blankets.

 

In correction to my previous post, there is tire wear, just a lot less than I expected. One race with 7 laps yesterday indicated 1% wear. I guess you can always increase the multiplier, but I imagined there would be more wear on the default setting.

 

Console pit status: uh.. non-status. Tire O-M-I readings are mixed up. Camber and Toe are mixed on some cars. You're better off just driving by feel alone.

 

Could it what the OP reports correlates to errors in-pit displayed values?

For the two issues I reported here I will open support tickets, unless anyone refutes my findings in the next days. In summary, the 37 degrees temps after a 20 lap practice session, and an expected 700 laps tire lifetime based on the 1% readout.

 

I would love to get that sort of Tyre life. been doing a lot of the Career and currently in the SLS GT3 Extreme series. be lucky to have the softs last 12-17 laps and keep par with AI on Very Hard without making mistakes.

I've personally taken no notice of the tyre temps but i do feel cars behave differently with different tyre pressures.
