Still not sure if best option but came across a short term, low cost fix. During lunch was searching online. Found a strange sale at walmart for 4 ply hi run turf tires.
Seems if I ship them to the local store I get an additional discount. So I ordered two tires to be sent to local Walmart. Total cost with tax just a little over $75.
