bad steering

I have an 86 iroc and have bad steering. I got the front end realigned and it still sux. What it does is it all ways wants to go right. Tires still have pretty good tread and I dont know what else. Its like driving on rails. please help so its smooth.
thx

Tire pressures are good?

Could be thrust angle from the rear end out of whack.

What does the wheel feel like? Nice and tight and the car just drifts to the right? Since you say the tread wear is good I'm inclined to think it's a rear prob as stated.

yup pressure in tires is good. the wheel feels like you have to keep turning to the left all the time because it drifts. im almost thinking that since i have the wider tires on the front also in back that may have something to do with it. So i may try narrower fronts.

No, the IROC's all came with 245's front and back.
Try to find a nice flat, newly paved section of road and see if it still does it. The wide tires on these cars tend to "follow" any ruts or wear grooves in the road beds.
