Front tires squealing under acceleration and turning... Anyone else experience this?

[dkyleb]

After installing my OME 885s, rotating tires(BFG Ko2s) and getting an alignment, my front tires are squealing on certain pavement while turning and accelerating. It doesn't happen every time, but still often.


I'm tracking tire wear, and so far so good... Just seems odd that I am getting squealing like this. It's definitely tires, and it's definitely audible.

(Center differential is not engaged, in case you're wondering.)

How smooth is the pavement and how new are the tires?

When I slap on new tires at work, the shop floor will make them squeal like banshees when turning.

Tires are about 80%, pavement is just typical road.... Not a squeaky shop floor or a parking garage.

You're feeling the effects of higher caster at low speeds. Think about the front wheel on a big stretched chopper (high caster), sits straight up and down when going straight but when turned the top edge of the wheel flops over to the side. Now think about a wheel with the steering axis straight down through the wheel (think 0 degrees caster), when turned left to right there is no change in camber. Measuring camber at a specific steering angle you can back calculate caster. *adding caster adds camber when turned*

I would guess there's some effect on tire wear but as suggested around here you're still in OEM specs so nothing out of the ordinary. Enjoy the better turning radius and straight line tracking!

Thanks for the reply!

But, what about when the squealing happens under straight line acceleration?

Hm I read that as during "turning while accelerating" not as two separate conditions. For tires squealing during straight line acceleration must mean you're really giving it the power or somethings locked up that shouldn't be giving more power to the front.

I am having a similar issue as well.
Get in the 2007 SR5 110k/mi and there is rpm dependent squeaking more times than not. Drive for a while at speed 45+ mph and will go away after a bit.
Stop to get gas, coffee, or cigs (just a couple of minutes) and it will come back...then go away after driving at speed for several miles.
If the squeak is not there first thing in the morning and I drive 2 miles to the general store to get coffee....it will be there once I start driving again.
Stock suspension to the best of my knowledge. Have only had her for 2 weeks.

Okay everyone, here's a video:

This is the road coming out of my work, where it does it the worst. It's under heavy acceleration.

You underestimate the power of the mighty 2uz-fe? You've got me stumped. Maybe try a ZPC? Might just be that road.

Both front wheels or just one side? Perhaps take it back to the alignment shop. I wonder if a stuck brake caliper could do that?

It did it before the alignment, too. And yes, both front wheels. Stuck caliper did cross my mind... But I'm not sure that would cause the squealing. It's definitely tire sound!
