Whining tires when braking with ABS

[Leif Jensen]

When I drive a car with ABS turned on I get the same whining sounds from the tires as when they lock up, but of course no smoke and feels like the wheels does'nt lock up - so why the whining sound ? It's disturbing

It's the same nomatter if I drive an Alfa Guilietta or a BMW Z4 GT3

Happy New Year

bad sound engineering.

You have maximum brake pressure applied and the ABS system is working to keep the tires in motion while applying the max amount of brake pressure for that to happen. Tires being on the edge of traction are making that sound. Also depending on the level of ABS you have applied to the GT3 car your Tires might squeal less or more. I guess ABS systems not being perfect tires might be on the edge of locking up before that's detected and they are allowed to rotate and brake power is modulated.

There is also a setting within the audio options that might have an influence. It's named "tire skid volume onset". Maybe I'm wrong, but I think it let's the sound "kick in" a bit earlier than it actually would be. It's there to give you some (early) feedback from the tires in compensation for the missing G-forces in front of your monitor.

If you set it to 100% it may meet your expectations better, but you have still to consider what Cristian said.

really helpful advice that. If you have nothing useful to say why post at all.

Just as when you are at the limit of grip your tires squeal, ABS does the same when braking. Everything normal there, it is a indicator that the ABS is working.

Setting the 'skid volume onset' slider to 200% and 'tire volume' at 3% made things much more realistic IMO. (still not perfect, but much better)

thx for this info. Will give it a go...
