I just noticed this recently when I started to get serious with the 1969X mod and the setups: I can't seem to get a proper amount of heat in the tyres with this mod.

In pribluda my front tyres always stay dark blue below 70 C. On some tracks I can get the rear tyres a little above 100 C (light blue in pribluda) but only when I keep driving really aggressive. Not ideal for hotlaps because halfway during a fast lap my rear tyres are cold again.

I tried increasing and decreasing the tyre pressure, but it doesn't make much difference. I don't have this problem with the Thundercars, instead there it's more of the opposite where the temps can get too high very quickly when driving aggresive.

Is this a known characteristic of the 1969X mod or am I doing something wrong?

Well, you won't get them up to temperature unless you want to go full lock with the front -which is considerably unrecommendable- and/or make donuts for the rear.

Otherwise, I get them into the light blue at best.
That said, I typically do not bother the tyres that much in 69 cars.

My rear tires are normally well over 100c after 10 laps.
It depends on the track how hard you lean on them. At Montjuic I have seen over 120c rears.

Fronts are easier to manage.

Could be running to much wing. Trade off between tire and aero grip.

My temperatures are higher when I use more downforce, on twisty tracks I can often get some heat in the rear tyres but on high speed track with low downforce they stay cold all the time. Getting the rear tyres somewhere around 120 C at Monthjuïc makes sense in that regard.
