Question about Tyre temp

After about 10laps my tyre temp looks like this --

Should i change each tyre pressure to make all about the same temp ??Also whats the best temp for a working tyre ??
Thanks for the concern.

i belive the optimum tire temps are around 90 dergees,but i dont know how this works in different time of day/air/track temperature or tire compound (soft,medium,hard)
If thats the case my tyre temp are far from optimal ... so i should decrease the pressure .. right ?? By the way is there any AC manual to confirm this optimal temp thing ??

Road legal tyres
Street and semislicks are road legal compounds, used on the road. They wear out slightly. Their main problem is overheating, but after you have overheat them you can wait and start again, they can give similar grip even after lots of km's. In the end they will wear and lose grip totally.
Street tyres optimum temp: 75°C - 85°C but "easy" under and over those temps. Very easy to overheat after some laps on a circuit, especially on fast corners.
Semislicks: 75°C - 100°C but a bit less grip under that and overheat quite faster over that. They have more grip of course and can resist more fast laps, but do not like much abuse and drifting. They wear gradually and lose grip km after km.

GT2 slicks: The main difference of the GT2 cars is that manufacturers are actively developing tyres during the season and bring different compounds on the various tracks. We can't of course simulate specific compounds for specific tracks, but we offer 5 different compounds
SuperSoft: 90-105°C Don't like to be driven under or over that range. They wear out very fast
Soft : 90-105°C as Supersofts. they wear out fast
Medium: 85°C-105°C as supersofts over their range. They wear out in a linear gradual way
Hard: 80-100°C a tiny bit easier than supersoft outside their range but nothing too radical. They wear just a tiny bit after the initial laps and then stay quite stable for a long time until they start to lose lot's of grip
SuperHard: 80-100°C as Hards. They wear a tiny bit and stay stable for lot's of laps until they let go.

GT3 slicks. The biggest difference between GT2 and GT3 cars are their tyres. GT3 tyres are fixed for the whole season and the organization decides what tyres the car have to use. We provide 3 compounds that are not equivalent to their GT2 counterparts (worse).
Softs: 80-110°C . Wear VERY fast. We've been told that they were actually used only for a couple of times in qualifying.
Mediums: 75-105°C Wear linearly and predictably. all around tyre
Hard: 70-100°C Wear a tiny bit after a couple of laps and stay stable for a long sting. Not great grip but they are predictable and can be used in a wide variety of tracks and temperatures. Often "forced" by regulations on cars.

The hypercars slicks (Zonda R and 599XX) are a bit worse parents of the GT3 tyres. Let's say a generation behind. Rest of their characteristics is very similar to the GT3 tyres.

Vintage F1 67 Tyres
We provide just one compound for such tyres, although we learned there were actually different compounds. As a matter of fact, there is documentation reporting that Jim Clark choose the tyre that permit him to slide more for the race at Monza. Unfortunately there is not enough documentation for the compounds so for now we stick with just one compound. If anybody has more info regarding the matter, I'd be happy to discuss with it.
optimum range 50-90°C The tyres are good at low temps, and can withstand overheating pretty well. The tyre wear is gradual, you can expect to do a full race without problems, except if you overdrive and overheat them too much.

The tyre ranges are not perfect ranges but a min max range that you might not be able to understand a difference in tyre grip. Temperatures are also vary quite widely from straight to inside a turn, so optimally you need a tyre that stays at the lower end of the optimum temperature just before the braking zone and at the higher end of the optimum temperature at the exit of the turn. Not so easy to obtain.
In AC going outside the optimum range, doesn't mean the car will become undriveable. This characteristic is a double sword. You might think the car is good, but you're not driving on the optimum grip, so you'll lose time without understanding it. There's depth to be found and explored within the AC tyre model.

Another hint for tyre temperatures, as in real life, use more camber to heat faster a part of the tyre tread and then this dissipate to the rest of the tyre. More camber, more heat, less camber, less heat.

Hope you find it interesting.

The inner and outer parts will rise in temperature when you lower the pressure. If you pump up the tires there is more contact with the center of the tire with the road surface which should see a significant increase in temperature on the center part.
 
So if i want higher temp i should increase tyre pressure ?? Thats quite confusing to me cause the game tell me the opposite, or i misunderstand something ??

So actually i should make the value higher or lower than 35 for higher type temp ?? :whistling:
Thanks again.
 
You should drop the pressues to 30 for that car and for more heat just increase camber. When you are cornering, the temperature difference is much bigger than when youre on a straight, so you should go back to pits a few seconds after youve done a corner to see what difference there is. Usually for GT slicks ideal would be around 90 cels and around 8-10 cels difference when in a corner. The middle temp should be inbetween inside and outside edge.

The inner and outer temperatures must differ between 6 and 10 degrees, with the inner being the hotter of the two. This is the rule of thumb I use anyway. Maybe the rears a bit less difference - say about 5 to 8 degrees. This is mostly affected by adjusting the camber. If the difference is too little, add more negative camber, if it's too much, decrease negative camber.

Tire pressure is what affects the middle part - the crown. If you have the above more or less correct, the middle temperature must be as close to in the middle of the outer 2 as possible. This means that you have as much of the entire contact patch on the road as possible, as much of the lap as possible.

For example, say the optimal temperature for a tire is 90, as above. That means the front must be at about:

- Front: 86 OUTER 90 MIDDLE 94 INNER
- Rear: 87 OUTER 90 MIDDLE 93 INNER

Now, obviously this changes a lot over a single lap, but the aim is to get it as close as possible to these values in places where you require the most lateral grip, i.e. fast, long corners - Pouhon, Istanbul Turn 8, etc.

Obviously everything is a compromise, as some values might decrease grip under acceleration out of slow corners, but as close as possible to these as you can get, is optimum.

Correct me if I'm wrong, please, as I'm still learning a lot about setups, but this is how I understand it.

Thank you very much for the tips. Looks like my tyre not operate at optimal performance consider all 4 tyre's outer/mid/inner temp actually quite the same :poop:
Thanks again :)
