A friend in our Model A club has had Coker American A tires for 2 or so years and really likes them. I have driven for years with coker 16” American Classic tires on my Tudor and have had good control in wind and rain.

I would check to see if your springs are sagging and if your shackles are at 45*.
Shackles too vertical can cause sway.
