I can't tell you what the official word is but I plugged my Michelin MXV4 energy tires by myself at least once, no problem whatsoever, run them down to the wires with over 90k. I don't see any reason why would they blow up after repair and if they slowly leak , the sensor should tell you, you have a problem and you go back to square one. Even regular tires sometimes can't be repaired properly and there are always risks in this type of repairs, but the best place would be to ask the dealer or have him do it, on the other hand he could make more profit by selling you new tires, so I would think it's your call. BTW, if anybody tells me you can't or shouldn't do something, my first question would be why?, otherwise I wouldn't accept the answer, but it's just me.
