New tires, loose rear end
 

So I had 2 new tires put on the back of my 01 tiburon. Alignment was done as well. As soon as I left, I noticed the rear end felt "loose". I had gone about 80 for a short stretch just to test what the tires do at a higher speed and the car felt as if it was going to start drifting. At normal speed (60mph) if I make a slightly abrupt movement (Equivalent to pass a car), the rear end fish tails a little bit. If I actually do pass a car, it feels like theres a full second after straightening the wheel before the rear end corrects as well.



Could the car being lifted at the shop break the seals in the struts? I bounced the back end by pressing down with the rear hatch open and it bounces once, then the struts catch the momentum....just like I would expect. But I can also rock the rear end back and forth and up and down pretty easily. IMO



BTW, yes it is stock struts. So I might be beating a dead horse, but I don't drive this car much so I am trying not to dump too much money into it.

I had the same thing happen when I got new tires in the rear. It goes away after a week or two.

There is a break in period for tires. After they've heat cycled a few times and worn off the outside layer they're usually better. Some tires also track differently if they don't match the fronts.

Ive never had that happen. I would take it back and make sure they didnt F something up.

Was the alignment out in the rear that they had to adjust it? They should have given you a printout.



Also over inflated tires can cause what your describing. See what they set the pressures at.

The alignment was fine in the rear. I had them recheck because I have the alignment under warranty for 6 months and I wanted to make sure everything was solid for my new tires. I have not checked the pressure but I will be doing that today!

Double check all the various nuts and bolts in the rear end and sway bar endlinks. Its possible something came loose back there.
