issues with brigdestone 960as...

i switched the factory tires out for the 960 as and now on acceleration car pulls hard to the left.. chevy blames tires....bridgestone blames car. this car is no longer fun to drive. its accually scary it pulls so hard. and when u let off it darts back to the right. i know there is torque steer but this is way beyond that. does anybody else have this prob since switching tires out.

OK, this is going to sound stupid but since this is a directional tire, did you make ABSOLUTELY sure that the tires were mounted and installed with all four going the proper direction?

Try swapping fronts to rear to rule out a tire or wheel.

I am considering these tires also, keep us posted.

Good point...I had them mounted at Firestone Complete Auto Care and they had one on backwards...made them redo it...

I don't know if this is the cause, but who knows...I can't believe that a place that is called Firestone and does tires for a business can be dumb enough to put 3 on the right way and then do one backwards...idiots...

Unless the tire is disgustingly low on air...it might just be your imagination. These cars do torque steer.

They do torque steer, but to the right, not the left.

With directional tires it can absolutely make a noticeable difference. And a lot of people are the same way - they figure you're paying people who know what they're doing to install tires. My best friend used to manage a Firestone and had a similar complaint from a customer. She took one look at the car, called the installer over to ask him what was wrong with his install job, he didn't know. She asked him why one of the directional tires was on backwards and he in all seriousness told her that "It don't matter cause tires don't go in certain directions, that all depends on what gear the transmission is in."

they are deffinatly all on in the right direction just triple checked thats was my first thought. it also changes when you put the stock tires back on (dealer swapped with stock unit to make sure it was the tires) when they put my wheels and tires back on it pulls again and its beyond torque steer. it really wants to go left. badly.

Google search for any recalls or known defects, check TireRack reviews and see if anyone else is having the same problem.

Malibu - Does your car have the limited slip differential?

How about you, TrevMo?

when you had your dealer check the tires by replacing with your old ones, and this steering problem went away, who put the new bridgestone's back on? the dealer or bridgestone? edit: also i know it sounds stupid, but check to make sure all 4 tires are exactly the same size.

swap the front tires and if it pulls to the right after the swap its the tires causing a radial pull if the car still pulls to the left it is the car. work at a tire shop deal with this problem everyday

my car does it sometimes too.. I think it may have something to due with the power steering. It does pull to the left especially under brake power stock tires .

Care to explain it and educate me? (road surface out of the equation)

This right here sounds like one side to me... unless you can magically swap axle shafts on the fly.

"TORQUE STEER

The steering veers or pulls to one side during hard acceleration. This is a common condition in front-wheel drive cars with unequal length driveshafts, and is caused by unequal toe changes as the suspension is loaded. Compliance allows the wheel with the longer driveshaft to experience less toe-in change than the wheel with the shorter driveshaft. This causes the vehicle to veer towards the side with the longer driveshaft. FWD cars with equal length driveshafts usually do not experience this condition."

Well then it's the road surface or proven physics is just wrong.

They use an intermediate shaft I believe. Which isn't a 100% absolute cure but helps a lot.
IF... one shaft IS longer then the other... It's definitely, absolutely... the right. (Tranny is on the left which has been the case with any FWD I've seen)

Here is an in depth explanation. They also mention pulling to the RIGHT if you read it all and give many causes that could worsen it.
http://www.aa1car.com/library/torque_steer.htm

Now if I'm WRONG... I just want you to explain it to me then so I'm in the know.
There are other forces that can cause a left jerk. The only thing I could even conceive as changing that principle would be the LSD.

The OP is convinced it's not torque steer at work anyway. So this is all really trivial to the topic anyway.

I guess that rules out any difference there then, you both have it.

I'm leary buying a set of these for mine. I have the LSD as well but am also considering the BFG g force SS A/S tires.
