What size tire on a 15x4 inch rim ?

Thank you very much for the info. I went ahead and ordered a pair of Nexen brand through work. Only ones we could get. I’ll see in a few days how they look. Think they were $90 something a piece
I've got a couple Nexen 165s holding up the front of my 55, temporarily, at the moment. Came off my Opel. They won't be staying on the 55. Decent tire. I think I paid around $50ea, pre-bidumb.
