Pair of new 28x12-12 atv mud tires / aggresive deep tread - sell or trade (Pevely)

Purchased for a four wheeler, but unfortunately they were too large and rubbed.
These are new with only a few minutes run time.
Still have the little nibs.
Mud Crusher Deestone 28x12x12 tires.
This is a large aggressive 6 ply tire with very deep lugs.
Install on your mud mower, atv, utv or any other project with a 12 inch wheel.
They Cost over $350 for the pair after shipping and tax, make fair cash offer.
I’ll also consider trading them for riding mower that works, atv / zero turn that needs work or ? No delivery, Pickup in Pevely, MO.
If ad is up then they are still available.
Thanks.
