I hope it's for camping or recovery gear. It is far too nice to use as a trash bag. It would make a great quick access recovery gear bag for a strap, shackles and small winching gear made of mud friendly material. Maybe keep the bag size limited to tire diameter (rounded bottom ??) and offer them in a few common sizes (31/265, 33/285, 35/315). I think you could have something there.
For a trash bag I prefer something cheap and durable like burlap or the man made alternatives. Something like the mung bean sack tied to my spare.
I'm sure there's a market for this, if it's not already being sold. You could research it online and see if it'd be worth it to start up your own website and sell it. You'd have to nail the keywords though. I think it'd double fine for trash, just make it easy to line it with a plastic bag that you can remove once it's full.
