New indycar tyre stuff

[Risto Kappet]

With all default settings, the cars tyres are screetching audiable just going in a straight line, the rear inside seem to be scrubbing that hard.

If you put rear cambers to minimum, the car starts slaloming by itself in a straight line

Is it normal?

Also, there are two clicks of "0%" differential settings

Oval setups often use reverse camber for the inside tires, this allows smoother turns. Instead of / \ you'll see \ \ camber settings. If you watch the race, the cars will complete a turn and snake down the two long straights, they allow the car to pull itself towards the inner wall to keep rolling resistance to a minimum. Then, they pull slowly back to the outside to begin setting up for the next turn at the end of either straight.
