Squeal in Curves at Speed

[Threehz]

So I've taken the thirty up the mountain multiple times, but the last two times I noticed a strange noise. One of those times it was just my girlfriend and I in the car, the last time it was us and a bunch of camping gear.

When taking on relatively tight curves at speed (40-50mph+) there is a slight squealing sound. It sounds like tire squeal, but the car is planted and I feel no loss of traction or control.

I was thinking maybe it is tire squeal, or maybe the tires are rubbing against the struts/springs... Anything else that would cause this?

Look at the inside wall of your tires for rub marks. If there is none then you had tire squeals. It does not take much for the rubber to protest.

Its your girlfriend

Most likely tire squeal. Try taking turns more slowly?

It's the car telling you to go faster

What kind of tires do you have? I remember with the previous all-season tires I had before, the tires used to squeal sometimes at speed around curvy corners and the car never lost traction or felt like it was skidding. I think the squealing tires were about at the limit that those tires could handle.

I now have some Potenza RE760 sport's which are ultra high-performance summer tires that don't squeal around corners at speed like the old tires.

How is your alignment? If the front is too toe'd out/in, the tires won't be following the optimum path around the corner and you'll hear a squeal.

There's 1 tire pressure for a driver and passenger and another with 2 people (or an equivalent amount of camping gear) in the rear seat. Adjustments range from 1-3lbs up front to 6-7lbs in the rear...depending on which car.

so...check your tire pressure :-)

My alignment is slightly awry, it's straight a lot of the time, but if I make a really sharp turn it will sometimes pull in that direction for a while (someone said this is probably upper strut bearings). The front tires are new, decent all-weather Falkens, and the rears I don't even know, they came with some wheels for free. Probably a combination of lame rear tires and off alignment.

Could be that combo of poor alignment and all seasons at high cornering speed workin together to inform you that your approaching your limit. I usually push untill I hear the tires protest because how else are you supposed to know if you could do it faster the tires know what's up
