[Spridgets] Tire time for my Bugeye

[Robert E. Shlafer]

They'll all "work", but assuming the stock
3.5" diam. wheels, you'll do better with the 70's. Matter of fact, you'd do better with a slimmer '78 or '80. 

More tire directly under the rim
...less "squishy" on turns and more crisp
initial turn-in, all else being equal.

And if you're using the stock 948cc motor, more "pep" with the less draggy, more slim
tire and better in the rain, too.....again, all else being equal.
