Tyre pressure different?

[OMG 77]

On set ups one side is different to the other?
Do you change it or is this meant to be like this?

it depends on how each tyre behaves under stress. therefore you have to put track characteristics into account and even out the pressure along all four tyres, so they even up under heavy load

? On which car/track? All? You mean the default/safe setup, or which?

Noticed it on aggressive setups all tracks and cars I think?

I will leave it different from now on.
So a track with more right turns will need lower pressure in that tyre because of the extra temps this is getting complicated.

I used to mess with tire pressure but never could get a good feeling. I just stick to the default, which I'm happy with. I never honestly noticed that they are different from one side of the car to the other. I know that front to rear they are different which makes sense.

optimal pressure for slicks should be at 28 to 31; for wet tyres its at 31 psi

however it depends a bit on the overall layout of the setup

keep in mind that you can run on lower pressures, but you'll be at risk to get a flat tyre

by design, the setups are suited to that track. On certain tracks you significantly tax one side of the car, thus the warm/real tyre pressures go higher. To counter this, you'd use asymetric cold pressures (what you see in the pits/setup screen) so the effective pressures are symetric while driving.

Makes sense, but never thought about it to this degree. Thanks

ya, you want them to be roughly equal when hot = while driving (after a few laps, there is some heat cycle going on during the first ~2).

In most situations this means your cold (= setup screen) pressures have to be asymetric (both left/right and front/rear), but usually we are talking about 1-3 psi difference only. Not dramatic, but having asymetric pressures while driving can lead to nasty imbalances and weird behaviour

E.G. Monza.

Left tyres high pressure, right lower pressure.

Why?

Many right turns -> tyres inside becomes cold, outside hot.

If the tyres stay cold they dont build pressure so the unloaded tyres need more pressure to balance them out once all hot.

At Monza no matter what you do right front will stay fairly cold so it needs higher pressure. Running uneven hot pressures is far from ideal which is why its best to make them uneven cold and balance out when hot. You can use pressures a little to try raise or cool tyre temps but having too big a variation in hot pressures has a big effect on car balance.

Id say 28 is more the max youd want to run slicks at so between 26 to 27.5 Much lower your risking a puncture. Too high your giving up some grip and sliding more. Too low its also a bit sloppy in corners but this is something you need to figure out per track.

Also with dynamic conditions if its very cold you need higher start pressures, slicks in the wet need more pressure but if it drys out your not going to be great so theres a fair bit of strategy with start pressures.

depends on the track you're on
