I was told that on my 08 Ford Focus that each tire has a bald spot. The tire man thinks sudden stops at high speed caused it, I rarely drive over 40mph in small town and I do not recall any sudden stops, any other possibility?
For an older car with well over 20,000 miles on it, I*d say you may need a tire rotation. However, your car is new, so your tire dealer is most likely correct.
With front wheel drive cars, the front brakes do almost all the work, For there to be bald spots on your rear tires, that means your brakes (front and rear) have locked up and caused tire wear. It may not have been multiple stops at high speeds...it could have been one hard braking at normal speeds. It may not stand out in your memory, or perhaps was when someone else was driving your car, but that could be what occurred.
It sounds like your tire dealer knows their stuff in this case, so I*d follow up with them for a course of action.

Sudden stops at high speeds do cause bald spots of tread on tires. Has someone else driven your car?
Ask the technician to point out these spots to you. A second opinion never hurts. Also, make sure your tire pressures are up to spec and your alignment is good. You can find the proper tire pressures usually in the driver's side door.
