chirping the tires

Is it easier to chirp the tires when they are new?

New as in 0 miles? New tires sometimes tend to be a bit slippery depending on how much mold release goo is left on them. This shoudl wear away by no more than 500 miles. After that some tires have a uniform tread compound and some have a sticky outter layer and a harder more wear resistant inner layer.

I seemed to be able to chirp the tired more easily when the car was new. I'm still on the factory conti shits though they now have 10 k on them

It would seem that chirping the tires isn't necessarily a matter of tire age but more so a matter of traction - the higher the frictional force between the tire treads and the road surface, the more likely you'd be able to chirp the tires during a rapid shift. Think back to the days where you had rubber bottom gym shoes on a shiny gym floor surface and just about every step you'd take would cause a chirping noise. Now imagine those same shoes with dust on the bottom across a dusty floor surface - not nearly as likely to chirp so I'd say the same idea applies to tires.

Of course VitaminT makes a good point - when the tires are brand spankin' new, they've got an ejection mold compound on the surface that takes time to wear off - that's the tire goo of reference. It's a bit oily to the touch.

They use cosmoline for mold release?
