Not every pull is an alignment problem
Before a vehicle goes on a rack, it is worth ruling out the two things that imitate a misalignment, because both are free to check.
Road crown. Roads are built with a slope so water runs off, and a vehicle driving on the right side of a crowned road is sitting on a surface tilting gently to the right. Most vehicles drift slightly that way as a result, and it is normal. The test is a flat, level surface, or the same stretch of road in both directions. A pull that reverses when you turn around is the road. A pull that stays in the same direction is the vehicle.
Tire pressure. A tire noticeably lower than the one opposite it pulls toward the low side. Check all four cold before concluding anything, since this is the single most common cause of a pull that turns out to be nothing.
If both of those are clear and it still pulls, the vehicle has something to say.
What the angles do
Toe does most of the tire damage, because a wheel pointing slightly off is dragged sideways for every mile. Camber wears one edge and leaves the rest of the tread healthy. Caster affects how the vehicle feels rather than how the tires wear.
A vehicle can feel entirely normal and still be destroying tires, which is why uneven wear is worth acting on even without a complaint.
When to book it
After an impact. When tires wear unevenly. When the steering pulls on level ground, wanders or sits off-center. When new tires are going on. After suspension or steering work.
A vibration rather than a pull is balance. An alignment that will not hold is suspension, done at this store, with the alignment afterwards.
