Michelin E-Wild vs E-Wild Gum X

[Beatn1K]

Im wondering what the difference is here, if any..?
There doesnt appear to be any kind of description forth coming from Michelin via Google , or the wider net...

I think ( I could be wrong) the gum is a softer compound, a bit more sticky

Don't the E-Wild only come in one compound option (although the front and rears are different compounds)?
