This is a great size wheel for big toys - but usually the treaded versions are chosen over this one as they suits trucks better. This one measures 63.5 x 19mm. Shown here with the AP-3000 axle peg installed in one, these are available separately and are not included in the price. The longer AP-3500 axle peg is also available separately.
The wheels are bought individually and discounts are available for bulk quantities.
