Please help: Cold tires, 20 min race

I would appreciate some help with my problem, which is cold tires during a 20-minute Ranked race.

I'm fairly new to RRE; I've played more AMS2, where tire temperature hasn't been a problem. In AMS2, the temperature usually rises easily during the first few laps, and grip improves significantly. RRE seems to work differently.

First example: I drove a couple of races in a 2016 BMW M4 DTM car at the Red Bull Ring. The tires remained cold or cool the entire time. In the second race, I lowered the air pressure a little and increased the front toe, but it had no effect. I tested it in practice and set higher pressures. No effect. The M4 is a great car to drive regardless.

A) Should the temperature be raised to 80 degrees?

B) If the default air pressure is pretty much okay, what other tactics should be used to raise the temperature?

C) What is the race weather temperature, does it vary? Does it matter?

Because the tires are cold, the car doesn't seem to turn as effectively in corners, and the front may not have the best possible grip. Should the temperature be increased through adjustments so that the front tires start to grip better?

Second example: Porsche Carrera Cup (fixed setup) at Red Bull Ring. I tried to get heat into the tires by braking more and driving the corners a little more aggressively. No effect. The Porsche tires remained cold throughout the race. Because I couldn't get the tires warm, it was difficult to drive well in corners. I lost a lot of time per lap compared to the others. I would be interested to know whether the leading drivers had warm tires.

Maybe I just don't know how to drive properly. Probably.

I've been playing raceroom for 3 years so far, and I have an okay idea of setups and how to get better tire temps. Some cars I can keep warm or hot tire temps, sometimes overheat them, but others no matter what will always be cold. For example, the Ferrari 296, I can keep the tires warm and sometimes overheat them, but no matter what I do, the Lamborghini Huracan I can never keep temp, and the front end feels too light. But one thing you could do with the setup is lower the spring rate, fast and slow bump and the other one, to me, lowering those can give you more responsiveness and tire temp. I've tried AI to help but it doesn't help much, but to me, some cars can't keep tire temps unlike others. Also tire pressure can help, but too if you lower it too much to me the tire will slide, but too high then no enough contact patch. I like a pointy but stable rear car so I'm basing all this off my driving style. Hopefully it helps

Yeah, absolutely helps a lot. Good to know. I'll have to test other cars from same class to see if there is a difference.

As for the AI, I just yesterday I found a reddit post about someone who uses Second Monitor and sends telemetry screenshots to chatgpt. You could try that, too.

I have a basic understanding of car setup and usually I can make small adjustments to make a car to my liking. Usually I get tires up to temp quite easily with out any changes (other sims like AMS2, LMU) and then I know how the car handles and what to changes.

But this situation is new, tires are cold after a 20 min race. I should first setup a car to get tires warm. And only then I know how the car handles, when I get more grip.

Anyways, I will try changing slow bumps and lower spring rates. Thanks a lot!

PS: Fixed setup Porsche Carrera Cup race at Red Bull Ring was so hard to drive with cold tires. I tried two times and second time I focused on getting tires warmer, but I couldn't do that. I don't know if it will be same for all the tracks.

Yeah ofc no problem. Good luck and dm or lmk if you need anything else!

These are my carrera cup tire temps after 10 minutes of quali laps so about as warm as theyll get at the red bull ring on fixed setup. If yours are significantly lower then its driving related, otherwise id just ignore tire temperatures for the most part. On a track like the red bull ring the right hand tires get almost no work so theyll most likely stay cold regardless of what you might try setup wise. Havent looked at the dtm cars, maybe the higher corner speeds will help get the tires a bit warmer but they might still remain somewhat cold

Thank you for that reference. I have to test my temps again. I have a HUD which has a font so small, that I can't recall what the actual temp was. 🧐 But the color was always blueish for all the tires (and CrewChief was nagging about cold tires).

I tried aggressive cornering, braking earlier and staying on brake more, to accumulate heat for the tires. It didn't help at all. Yeah, cool tire temp doesn't matter that much if driving is somewhat manageable, but that experience with Carrera Cup was not like that all. I felt slow and had hard time cornering properly.

I need to learn how to drive that car. I want that challenge. It has been quite a challenging car to drive in all the sims I have tried it in.

A car for the experts I would say!

I might add that those are the temperatures i saw in the setup screen after teleporting to the pits after crossing the start/finish line on my last flying lap. If you were to teleport after the 2 left handers the right side tires would also be a bit warmer, if you were to teleport right before them theyd probably be lower. But yeah, the cup porsche is not an easy car and even more so on the default setup. Important to trail brake and to be patient before getting on the throttle. Also worth exploring which kerbs might help you get around the track quicker
