Out-of-round issues can be easily found. The vibration will not go away at any speed if it's a wheel problem. At low speeds it is less noticable but still there. Tires are a little tougher because the vibration at low speeds will be almost not there but, the sound the tire makes will give it away. Balance problems come and go at different speeds.
Alignment issues can always be a problem because the specs for any car have a variable built in to allow for component wear and road irregularities. So even if your car is within the specs it may still not be perfectly aligned. Some performance alignments even add in camber to increase cornering traction but, that does sacrifice tire life. Tire wear that is circumferential and smooth does indicate a camber problem or excessive cornering speeds. Tire wear that is circumferential and feathered or staggered like a stair step indicates a toe in or toe out condition (toe in for outside edge wear ... toe out for inside edge wear).
Hope this helps
