You may have a tire with a flawed sidewall that will cause a loose feeling. I don't know what tires you put on it but if you don't see anything else have them examine the tires. I'm assuming you rechecked you tire pressures too.. I had mine done and they i didn't like the feel...found 35# all the way around.

good luck

ps you shouldn't run SO2's and SO3's in combination it's not recomended or so I have been told

 

i have s03's all the way around. checked the tires everything looks fine. i think i just kinda adjusted myself to driving the bald tires. the more i am driving on them the more i feel more stable. i'm having a feeling that they just need to break in a little more.

 

Yea, I felt the same way when I first bought my tires. But I bought some RE750's and they aren't as rigid as S02's. But I wanted more tread life and water stability and that was a trade off that I was willing to make. At first I felt like I was driving a Tarus, however, I am use to them. In fact, they feel better at higher speeds than S02's and S03's. I have been up to 150 MPH and felt fine. In my S02's I felt like a rock would send me flying off the road.
