The tricked Avons will look the closest to this, the Goodyear Polyglass tires.
Personally I found that on the front, a 235-60-15 is big enough, gives nice clearances and you will see a tremendous difference with a radial tire instead of the Polyglass tire. Those are for looks and ride and handle like they are made out of concrete.
Here is the 295-50-15 on the rear with the 10 spokes. Notice the space between the tire and the fender.
