Check the pressures before you book anything
Pressure moves with temperature, and here it moves a lot. A tire set correctly on a cool morning reads noticeably higher in the afternoon on hot pavement, and the swing between a winter morning and a summer afternoon is larger again.
That matters for a vibration complaint because a tire well away from its specification changes how an assembly behaves. An over-inflated tire rides harder and transmits more of whatever is there; an under-inflated one flexes and behaves differently again.
The sequence worth following is therefore to set all four cold against the specification, drive it for a few days, and see whether the vibration is still there.
A good number of vibration complaints resolve at that point, and the ones that do not are real findings worth paying somebody to look at. The check costs nothing and it tells you which you have.
What cold actually means
Before the vehicle has run, which in practice means first thing in the morning. Not after a drive to the store, and not in the afternoon.
A reading taken on a hot tire is higher than the tire's actual cold pressure, and bleeding air out to reach the specification on a hot tire leaves the tire genuinely under-inflated once it cools. That is a common and avoidable mistake here.
When it is balance
The national tire and wheel balancing page covers the occasions worth asking for it.
A vibration that sits in a speed range and fades either side of it is balance. One at every speed, or with a pull, is alignment or something worn, both handled at this store.
What is not here
Wheel refurbishing. If a vibration survives a balance and the rim is suspected, that work is at Reno, Fernley or North Las Vegas.
