Mark Warwashana (734-449-7355) has wheels that are 3/8" wide at the hub and are 2.25" in diameter.
These are, to my understanding, clones of the old Veco "grasscutters". The hard streamlined tires we use to always use on the I-Beamers with sexy wheel pants.

Have to order some when my present supply is gone.
Tom Morris, Jim Snelson, and Randy Smith all sell the Dave Brown sponge wheels for thos of us with no in town Hobby Shop.
Hey, Randy! Take apart wheel pants are a breeze, so what difference does th e tire make?
