Crack in tire

[BigRedster]

I went out riding yesterday as normal, and on the way back, my right tire went flat. I looked like an idiot riding home on two wheels :oops: (all lopsided), but I made it home 8) ...I see the crack, it's about an inch/inch and a half long. Has this ever happened to anybody? How would I go about sealing this tire?

The nuts on the tire are extremely tight; how do I go about unscrewing?

not entirely sure what you mean by "crack" in the tire, is it tubeless?, i would get some tire plugs and puts some in the "crack", then put a bottle of SLIME tire sealent in the tire

or worse comes to worse... a tube will fix it..
