Why do teams use different camber with same tyres?

[hardingfv32]

1) You are making these camber judgments based on photos?

2) With everyone using the same front tire, can there be much difference in front camber between cars? In general is there not an optimum camber for the front tire?

Given all the cars roll differing amounts, angles and have different compensation rates. No.

Well we got two dry tyres every weekend minimum ...so from that alone there is an awful lot of compromise potentially optimising your car for use of both.

"Given all the cars roll differing amounts, angles and have different compensation rates."

Yes, but shouldn't the final camber numbers for all cars be the same at max cornering G's? Wouldn't this be where the tire produces max cornering performance? Shouldn't everything be done to give the tire exactly what it wants?

Tire compounds: how do different compounds effect the camber requirements? Isn't the construction the same?

For discussion purposes I am assuming that we are attempting to get max performance from front and rear tires. I appreciate that some reduction in performance at one end could be required for balance requirements.

AFAIK camber is to maximise contact patch when the car is in roll. Theoretically, when you make a car stiffer, it rolls less, and you should put less camber. When you have it softer, and let it roll more, then more camber is ideal.

[hardingfv32]

Why wouldn't the camber curve be designed to match the amount of roll you have?

I guess we should specify that we a talking about camber at max cornering force, not the static setting. Should the camber setting for all cars be about the same at the max cornering performance point?

Brian

[raymondu999]

It would; but then each different team's cars would have different suspension settings which would dictate different amounts of roll.

[HampusA]

All cars are different, one number might not be the same for the other teams.

[PhillipM]

Might not even be the same between cars in the same team...

[hardingfv32]

So... you are say that the tires have a variable sweet spot? That you can get equal performance from the tire with different maximum cornering load (dynamic?) camber readings?

Brian

[raymondu999]

Sounds like a question for JT; and for a new thread.

Why would it be so impossible ? Cars do have other variable sweet spots, that we know for sure, like balance,wing AoA,suspension settings...etc. It's too dependable of the driving style. We could see all year that teammates having quite different setups, could be alongside each other in qualy and race too. (IMHO)

[hardingfv32]

The driving style in the case of a spec tire needs to be configured to optimize the tires performance. Some drivers will need more setup compromises than others to optimizes tire performance, but the fewest compromises equals the highest level of optimization.

No, not really that simple.

[hardingfv32]

Hoping to learn something.... Why not?

I am assuming that we are trying to get max performance from front & rear tires. Also, we do not have to degrade the performance of either end to solve some kind handling problem or driver preference.
