[Closed] Is my tyre dead?

Just put a hole near the centreline of a brand new 29er Nano 2.1 which was on the back of my Longitude. I got a bit over enthusiastic (for me) going down a rough track. The split is about 8mm long. Are splits like this fixable, or is it time to chuck it? Although I put the tyre on myself originally with little difficulty, it proved impossible to remove in the field today to replace the innertube, resulting in a two mile trudge home. If the tyre isn't salveagable I might as well cut it off, it'll save me the hassle of wrecking all my tyre levers.

Looking for recommendations to replace it with - it's for bikepacking, bridleway stuff, nothing heroic. I want something that isn't a nightmare to remove and replace in the middle of nowhere (Alex MD23 rims, currently not set up tubeless but that may change).

cheers
