Hi, For those looking for 13" tires I would suggest https://www.onlinetires.com<https://www.onlinetires.com/> . They have an extensive listing of 13" tires. I purchased the Federal brand Formosa 205x60x13, H speed rated, for $52.51@! Been quite happy with them. Agreed 13" are a lot harder to find and only going to get worse. Cheers, Curt Bowland
