It certainly should be strong enough, and 50’ seems like a good length. I might get that myself.
Edited to add: Make sure you have some way to connect it to your vehicle.
That synthetic winch rope in the Amazon link from Russ is not the one you want. That rope has a thimble (buckle) on one end and probably has a flat connector on the other end to attach to the winch.
What you want is a synthetic rope extension that has a thimble on each end like this one.

https://www.amazon.com/Keeper-Original-Version-04228-Premium/dp/B00I5HRTU4To tie everything together, use a shackle - but you first need to know the max diameter of the above rope thimble. Hard to tell in the images, but looks like it may accept at least a 5/8 inch shackle pin such as this one.

Axle strap on vehicle>>>Shackle or Clevis hook>>>synthetic rope.
I run a very similar setup, but use recovery straps as the synthetic rope is meant only for winching / straight pulls and not to be used as a stretchable / jerking recovery strap.
Above all, practice, practice before using in an emergency.
