You could use some modern R compound tires from Toyo or Hoosier. Some Toyos shaved to 4/32 will work in the rain just fine, or if rain isn't a concern then get the Hoosiers. Easy size selection, 275s in the rear, put some 225s in the front. You'll be faster than the Goodyears and Avons, and your wallet will be happier too I think!
