PURPOSE:To eliminate the need for machining a wheel with a hollow wheel by communicating an auxiliary air chamber formed to a wheel body made by casting and a rim part of the wheel body as well as a main air chamber enclosed by a tire by a communicating hole formed to the rim part. CONSTITUTION:The Al alloy hollow wheel provided integrally with the rim part 2, disk part 3 and hub part 4 to the wheel body 1 is formed by casting and the communicating hole 8 is preliminarily opened to the rim part 2 in the stage of casting. The wheel body 1 formed by casting is fitted to a tubuless tire 6 and thereafter the main air chamber 7 enclosed by the tire 6 and the rim part 2 and the auxiliary air chamber 5 are communicated by the hole 8. The wheel with the hollow wheel made by casting which does not require particular machining is thus obtd. and the production of the wheel suitable for mass production is made possible. |
