Looks pretty cool. How long is the probe going through the tire? Are going to hit the rim tape?

The plug goes inside the end of the probe, it is inserted just past the end and the domed head pops out of the probe when using the Allen wrench to push the plug out of the probes end, when you pull the probe out, the domed head/shank catches on the inside of of the tire casing, pulling out the glued dome and the head pull up tight against the inside of the tire casing, seals and plugs the hole.
Inside air pressure helps, refill the tire with the required pressure needed and on down the road you go.
I don't know if a fat tire bike casing would be strong enough to keep it's shape while inserting the probe? I would believe that with any amount of tire pressure, that would be the deciding factor, I have never had a flat fat bike tire in my hands to play with yet......
With a bike tire, I think, I'll pump the tire up with as much air as possible with the probe in the leaking hole, when pull the plug out, should help............?
They have several different lengths of plugs, and plug head diameters,
I always used largest diameter and the long stemmed plugs,
then pulled the head up tight inside the tire casing, to make sure I got a good seal, then cut off the shank end flush with the outside of the tire.
The shank end is pretty stiff and the domed head is very soft/ flexible and seals very well when pulled right up to the inside the the tire casing. When you clean the hole and insert the probe, I always applied some extra glue into the hole/around the probe, and I spun the probe when removing, to make sure the head flared out, and sealed, was easy to insert/spin etc.
