Yes, cooler tires give you more mechanical grip in the middle sector. "Cool" just means closer optimum, not cold (so no issue in high speed for Mclaren). Red Bull tires run higher than optimum temperature. The RB21 is by no means a perfect car and they have balance "issues" and some understeer but the biggest performance differentiator right now is the overheating of the tires. They run big rear wing in vain (cost straightline speed) and just makes car even more compromised. If they can cool the tires, it will unlock a lot of the potential that is there from the aero package. Even in the qualifying lap, Mclaren gains some tenths because the tires have a stable temperature across the lap. Max struggled in qualifying in Miami to have tires at optimum temps for all of the sectors.
It was hotter during the race in Jeddah than in Miami both in terms of air and surface temperature. Same C3-C4 compounds. No overheating whatsoever in Jeddah, but suddenly a lot of overhearing on C3 hard immediately out of the pits? Makes very little sense if any at all. I see a lot of copium here in this thread. Mclaren is just faster race car, much faster race car on some tracks, just like red bull was much faster race car than Ferrari since Spa 2022, or Mercedes was much faster race car than the RB16/B for the large part of 2021 season where Max could be faster by as much as 3 tenths in Q3 on soft, but would be significantly slower on medium and especially hard on Sunday. Slower and with more deg.
Miami - day race, sun beating on bodywork, tires, and tarmac.
Jeddah - night race, no sun.
Jeddah - high average speed, 2nd highest of the calendar (251 km/h)
Miami - bottom 10 average speed (224 km/h),
Higher average speeds leads to more cooling of the tire surfaces by direct contact with the airflow and more airflow into, in and around the brake ducts/tins.
Jeddah - front limited, less sensitive to rear tire overheating
Miami - rear limited, more sensitive to rear tire overheating
There are many reasons for the different outcomes at each race. Cooling the tires more will not be "Easy". If it were, everyone would already be doing it. However I think if Red Bull could implement something that is more effective, they will unlock a lot of performance from the current package. They would be able to run less rear wing, more consistent braking performance, more energy to harvest, more grip in low speed, less tire degradation, less thermal degradation, more pressure on the Mclaren drivers. Smalls details can have a big impact.
It doesn't turn.
