The tires I got in Avon Bias Tires and had them Groved Sizes were -

8.5/23.5-15 Fronts
14.0/27.0-15 Rears

Fran can comment on the fitment on them. BillD's tires ara just a tic bigger in the front and rear, but I figured I would go with bit taller tire (27 vs 26) due to the low final gear ratio that I have. Use one of the gear calculators and you can see how the diameter affects your RPM through each gear.

Here is the link to a good simple program GearCalc
