the answer is simple: if you run your tire pressure within the intended pressure window, higher pressure will allow you to keep more heat in the tire, due to the reduced capacity the tire has of absorbing bumps. The high temperature will be core temperature. HOWEVER if you run the tire pressure BELOW the designed pressure window, you will ALSO overheat your tire because of the rubber deformation, which is is carcass temperature, and generally doesn't matter for race tires because rubber deformation can't really warm up the tires much more than 60 or 70 degrees at the worst cases.
Both are right. Its just the reasons why are different. Its pretty much the difference of surface vs internal temps. General rule of thumb though. Higher should always mean higher temps. Lower is when its a combination of factors
I ran 5 laps at Misano on ACC and on the lowest tyre pressure it was 10 degrees hotter than my normal setup & with the highest pressure it was 11 degrees cooler. All measured at the same point on track, same track temperature The higher pressure setting also gained less pressure over the 5 laps than the low pressure tyre but it was undriveable, 6 seconds slower per lap. Obviously those are taking the pressure to the extremes. From real world experience within motorsport we didn’t really try to resolve tyre heating issues with tyre pressure we focused on dealing with setup/balance issues that were causing the overheating. I feel like sims are quite poor at replicating tire pressure and its effects over a stint.
before any meat mangler goes crazy at me, Im not saying Jarno isn't a real driver. What Im saying is F1 is the game, and I doubt F1 drivers stand 3 ft ontop of the car seat when driving, so unless they want to make the competitive scene less arcadey they should force cockpit cam. Nothing against Jarno.
