tires wearing

[wagonwx]

A friend tire are wearing on the inside (looks like a front tire that is out of alignment).  Is this an alignment issue or sagging coil springs or something else?  He got an alignment at NTB when he got the tires. But I don't know if they know what they are doing.  Any advice , Recommendations

Likely its something simple, such as worn tie rod ends causing the true alignment to vary a bit since the wheel can wobble, or maybe bad wheel hubs. if a celica like these, i know my rightmost tension rod to chassis bushing is blown out, which makes it impossible to eliminate my right pulling, and causes light vibration during braking on that same side.

Celicas and most cars only have the toe set and caster/camber are not adjustable in stock form. If a car is lower than stock it alters the caster/camber.

I used to do alignments, if the customer got tires and an alignment and I found parts that were worn I would tell the sales guy and a lot of times the customer would refuse to have us repair them. Then they would expect a perfect alignment. What we would do to make the toe look perfect is get it as close as we could then we would call another mechanic over and push or pull the tires to aim the toe into the perfect green zone so the printout looked good.

One of the best ways to look for play is to have someone steer the car back and forth on asphalt while you look underneath. Wheel bearings you want to jack it up to look for play.
