^ Are tire temperature indicator boxes around tire.
If they are working now or not is the question.
I don’t think those are actually tire temperature indicators, I believe those simply indicate excessive, or unusually rapid wear, not exclusively linked to tire temps.
Increased temperature is definitely a factor that promotes increased wear, which is why it’s not uncommon to associate those indicators with tire temps, but those don’t appear specific to temperature, but wear rate in general. If they were specific to tire temps, and worked even remotely close to something that’s accurate or realistic, then they’d light up red on the IM and Wet tires being driven on bone dry pavement real quick, which isn’t the case, nor has it been in GT7 that I ever remember.
To that end, I don’t think PD has ever clarified exactly what that indicator truly represents. If it does represent tire temperature and only tire temperature, it’s incredibly inaccurate and useless in that regard based on how it actually works in race. If you spin out at high speed the leading tires in your slide across pavement with the most pressure on them light up red after a second and then immediately go dark once stopped. If you do a burnout where tire wear is a factor they will light up after a bit but then immediately go dark once you get traction. If these indicators were specific to temperature alone they would/should stay lit up for awhile afterwards until the tires cool down, instead they immediately go back to normal once the rapid wear is done.
 
I'm surprised that no one has noticed that the Ferrari VGT actually has a tire temperature display on the steering wheel. The temps are displayed as colors ranging from green to brown. You start with green tire indicators and after a while they start turning yellowish as the tires warm up. Once you stop it takes several minutes for the indicators to turn back to green.

Here's how it looks like at the start:

After one normal lap:

After another lap intentionally warming up the tires by weaving from side to side:

After stopping had to wait about 3 minutes for the tires to cool down / turn back to green. Wheel spin and high speed cornering also causes the tires to warm up and indicators to change color but only for a short period of time.

The display also shows tire wear and pressure.

It’s in the online manual that no one ever reads

“ As the tyres get hotter, the outside frame for the four tyres will get redder”

Thanks! Seriously, I’d never seen that there in the manual before. Admittedly, the last time I looked at it was release day of the game.

Now we know it’s actually documented by PD that they attempted to include tire temp monitoring in GT7 and described how it should work, it just doesn’t actually work that way, or how one would expect in regards to temperature of tires, or anywhere remotely close to being realistic or useful in regards to indicating tire temperature during a race.
In fact, the only time I can ever get that indicator to turn red is when I slide at high speeds or do a burnout. The way it actually works is completely useless in regards to knowing tire temps and only really lets you know your tires are currently undergoing excessive/rapid wear due to increased friction.

I’ve driven lap after lap with completely bald/worn tires on dry surface before (albeit many, many updates ago at this point) and those never turned red for even a second when in real life they’d be as red as red can get.
 
I do apologize for having played Gran Turismo from the demo disk days til now. 😉

Would sure be great if the UI actually did this in the game itself...
Proves it's at least part of the telemetry even if you can't see it.
Fresh out the pits there's definitely a reduction in grip for the first lap or 2 before the tyres warm up. It would be nice to see when they're at operating temps though rather than just feeling for it
 
Tyre temperature does display in the HUD. Generally the way it works is that when the tyres are very hot or very cold, the indicator (outline of the tyres) will display as a shade of red or blue. Otherwise it'll just be grey.

The easiest way to test how it works is to look at the tyre indicator when you can hear your tyres screeching. The tyre/s you are putting load into will be displaying as red, then it will be back to grey in a few seconds.

Time for some donuts me thinks
 
Indianapolis 500: The Simulation had tire temperature simulation in 1989 (probably more advanced than GT7's, honestly). It's really not that hard to do. The vast majority of the power increase in consoles and PCs since then has gone to graphics.

You just don't get it, while a 1990 PC could handle it, the PS5 is still using console-specific vacuum tube transistor processing units that use the majority of its processing power to keep the clock more or less accurate.

Would it be a stretch to suggest kaz does not AT ALL care about how much of a "racing simulation" GT7 is? Clearly if anyone wants a simulation, they'll play it right now, realise it's not cutting edge in that department, then play iracing or literally any other simualtion on the market which is far better value than GT7.

Probably not, since he calls the game "The Real Driving Simulator," not "The Real Racing Simulator."
 
Yeah. But even then it doesn't really qualify as good enough to be a "driving sim" on par with the rest of the simulations. Just interchange the word driving for "racing" and you have an even bigger crowd that thinks it stinks.
Not to mention there's not much of a "driving sim" crowd. the crowd is all about "racing/hotlapping sims" these days. Driving? that's boring!

When are you seeing this indicator turn blue? Is this exclusive to a certain tire type or race or something?
I’ve never seen it blue, only grey or red, so I hopped on at lunch and did a race at Sardegna in the Audi RS5 with RM tires and it wasn’t blue during the pre-race countdown, at the very beginning of the race, anywhere during the first lap or even immediately after leaving the pit where I put on fresh tires.
I started a race at LeMans in a GT-R GT500 on IM to see if it was blue there during the countdown, at the beginning or after a pit stop where I got fresh tires and it was always grey for me.

The only time I've seen tyres going blue is on the straights at SS Route X.
 
If tire temps have a bigger affect on handling now, then PD should adjust the display to not only show the extreme values.

For cold tyres you usually have to wait several minutes to see anything on the indicator, even then you'll probably notice the lack of grip before seeing anything on the indicator, as it's pretty faint.

The easiest way to test is to go to World Circuits > Any track > Time Trial, stop and wait for 15 minutes, but you'll see it happen at SSRX as well. These screenshots appeared brighter on my monitor but hopefully it's clear enough to see the difference:

The only time they turn blue is after you’ve been at a complete stop for around 15 minutes straight? It truly is mind boggling sometimes the things PD puts effort and resources into.

No, that is just the easiest way to visualise it, because you can park the car and do something else for 15 minutes.

As mentioned elsewhere in this thread, you can also do a lap or two of Special Stage Route X in a road car and you'll notice the same thing happen.

But it can happen in any track/car/tyre combination where (for whatever reason) there is not enough energy going through the tyre/s to keep them in their ideal operating temperature.
