If you bought the Heliums based on a reputation for quality, and they are holding up, you should leave them alone until there's a problem.

You might check with Mavic to confirm that they're within factory spec, and if so leave them alone, relying on Mavic's judgment about what's called for. To buy a high end product then decide the maker doesn't know what he's doing, is comparable to going to a doctor, then telling him his course of treatment is wrong.
