Default Alignment expert help. Uneven tire wear on one tire

Help me you guys. I have had Falken Azenis sports for the past 10K miles. I've rotated them 3 times already (front to back). My suspension is stock except for sway bars, which shouldn't affect alignment anyway. Just now I noticed that the drivers side rear tire is wearing unevenly (inside edge of tire is getting worn faster than rest of tire). All other tires are wearing evenly. I also noticed since my last tire rotation that my steering wheel shakes when at 60mph or above. Is this an alignment problem? If so, what type do you think it is (i.e. camber, toe...) I'm gonna get new tires soon so I would like to know if alignment is necessary. I know that camber isn't adjustable in the rear. If camber is the problem, can camber bolts solve this? Thanks.

You probably have a toe problem. Since you have uneven tire wear I would definately get an alignment with the new tires.

I agree with StiDreams. Get an alignment done when you get the new tires and make sure to get them balanced well.

inside edge usually means excess toe out. If it were excess camber it wouldn't be concentrated on the edge and it would be more like the inner half or third of the tire. Steering wheel shaking could be a lugnut issue, if they're not all torqued down you will definately get vibration but usually at lower speeds too not just highway. What kind of wheels are you using? Maybe wheel weight issue also

Tires don't magically wear unevenly, so you definitely have an alignment problem (almost certainly toe out, as previously discussed). When was the last time the car was aligned?

The vibration is probably a missing wheel weight, as tdxflex mentioned.

thanks for the replies. I'll check on the lugnut tightness issue. All of the wheel weights are still there. I'm using stock rims. Car has never been aligned. I know i probably should have had it done since I'm already at 48K miles. Tire wear has always been perfectly even unitil now. The uneveness has occured for at most the past 2500 miles.

Should I buy camber bolts and have them for when the alignment is done?

So, tire wear was fine for ~45k miles, then all of a sudden your right rear starts wearing unevenly, and you develop a vibration at speed. What did you hit 2500 miles ago? Obviously something knocked that corner out of whack, and you may even have a bent rim (hence the vibration). The second part is just a hypothesis, the rim may be fine, but something has to have happened to that right rear to cause a distinct change in wear patterns.

As previously mentioned, this isn't a camber problem, it's a toe problem. Toe is adjustable on the rear suspension, so there's no issue there. As for whether other parts may be needed because something in your rear suspension is bent, I dunno...

Thank you for the advice Pat, even though you were a little harsh

Don't remember hitting anything that made me think that it could knock me out of alignment...ohh well, I'll be making an appointment at West End. Hopefully its just the toe problem as mentioned.
