Read the wear pattern before you book anything
Uneven tire wear gets reported as an alignment problem, and some of it is not. The pattern tells you which, and it is worth knowing before you pay for anything, because the two cures are completely different.
Worn in the middle, shoulders fine. That is over-inflation. The center of the tread is carrying more than its share of the load because the tire is too round. Alignment has nothing to do with it.
Worn on both shoulders, middle fine. That is under-inflation. The tire is flexing and running on its edges. Again not alignment, and on a highway vehicle it is also a heat problem.
Worn on one shoulder only, across one tire. Now you are looking at alignment, specifically camber or toe.
Feathered across the face, smooth one way and sharp the other when you run a hand over it. That is toe, and it is the classic alignment signature.
Both-shoulders and middle-only wear are pressure, and pressure is free to fix. One-sided and feathered wear is geometry, and that needs a rack.
A fleet that checks the pattern before booking saves the alignments it did not need and finds the pressure problem it did not know about.
Pressure matters more on a highway vehicle
A tire running on a long highway leg at the wrong pressure is doing it for hours continuously, which is a different exposure from the same error in town.
Set pressures cold against the specification rather than by eye, and recheck them, since ambient temperature here moves them around more than people expect.
When it is alignment
The national alignment page covers the occasions and what each angle does. An alignment that will not hold is suspension, handled at this store, with the alignment afterwards.
About this store
The Fernley store runs sixteen services, carries all nine Purcell tire categories, and is managed by John Jangula. It also aligns heavy trucks and trailers.
See the national car and light truck alignment page for all 40 locations.
