A shake that fades after a few miles is not balance
An out-of-balance tire shakes the same way every time you reach the speed where it shows up, whether you have been driving for two minutes or two hours. Some vibrations behave differently, and the difference tells you where to look.
Worst first thing in the morning, then gone. A vehicle that has sat overnight, especially in cold weather or after carrying a heavy load, can develop a temporary flat spot where each tire rested on the ground. The first few miles thump or shake; as the tires warm and round out, it fades. That is the tire's construction, not a balance problem, and it usually needs nothing. If it never fully fades, or gets worse over weeks, have it checked.
Only when braking. A shake or pulsing through the pedal or steering wheel that appears when you slow down, and not when you are cruising, usually comes from the brakes rather than the tires.
Gets steadily worse over days. A vibration that grows is worth booking promptly. A tire separating internally can start this way.
Constant at one speed, smooth above and below it. That is the classic pattern of imbalance, and balancing is the right first step.
Before you book
Note which pattern you have. Check pressures cold against the specification on the door label, since a tire well off its pressure behaves differently. Note the speed and whether you feel it in the steering wheel or the seat.
When it is something else
A brake-only shake goes to brake repair, and a pull or uneven wear points to alignment, both here. The national tire and wheel balancing page covers the occasions worth asking for balancing.
