I've been having a problem with the contour of the road pulling my car one way or another for about a month now, had her up on the racks to check out everything in the front end, bushings, ball joints, sway bar links, ect...
Everything seems okay but it's seemingly getting worse and has me a little concerned.

I'm kinda hoping someone will bring something to my attention that I may have passed up

You need to indicate what wheels and tires you have and their condition. Also what pressures you run.

Eagle aloy polished alum. 16's
Not sure the tire size, I'd have to check

Back tires are about 80%

Fronts are mismatched with 25-30%

And I run em at about 32psi, any lower in the front and I get a wobble which I'm sure is due to the front tires being out of balance

This could very well be the issue.. Though it seems almost too drastic to be the tires

Either way, I havnt tried rotating front to back yet souly because I had a pretty knowledgable friend of mine tell me tht putting mismatch tires with uneven tread wear on a posi rear will cause damage

Is he right?

Buy new tires.

KFtransam

Yeah, but untill I have the extra money, will I tear up the rear end throwing them in the back?

When you say "tear up the rear end", are you referring to the posi unit, when the rear tires' OD is mismatched? If so, YES, it's possible.

KFtransam

They are both 235 55's ones at about 50% and the other is about 30

buy new tires.

KFtransam

Yeah thanks...

Now anyone who wants to help out?
Am I gunna damage my posi?
Same size tires, tread is worn differently

lt1slowz28

it will be fine, but mix matching different brands and makes of tires isn't really helping your issue. Pony up for some decent tires, it makes a world of difference.

I plan on buying tires next season, but for now I'm saving up some cash for a winter beater so untill then I'd like to just rotate tires, the backs are a matched set

I wouldn't put the more worn ones out back. If your saving for a winter car and don't quite have one by winter your not going to want bald tires back there. I would think your pulling is from the mismatched fronts though.

You can potentially do damage to the rear with different tires on the rear. Will it happen to you, nobody knows. It depends on how mismatched the tires are, the way you drive and the mileage you drive.
From the description of your tires they are most likely causing the steering issue. Yes it will continue to get worse, likely at an increasing rate.

The only solutions you have are to get new tires, stop driving it, or deal with it and know it's going to get worse.

Re-read post #6...... I know this from personal experience.

KFtransam

Maybe I'll just find a decent set of matched used tires to throw up front, I jacked the front end up today and gave the passenger side a spin.. Tires a little out of round, possibly a broken cord or something

Deffinately my issue though as it seems any rut on the passenger side almost causes an off road excursion

Does that checking everything also include a four wheel alignment?

KFtransam

Nope, though its not tracking either way in the rear nor is it a consistent pull to one direction..

I'm pretty sure it's this one tire and now that I think back, I'm pretty sure I can narrow it down to exactly when the problem started...
Ran over a paver brick about a month or so ago and started noticing a little wobble after that
