Abstract
A wheeled tire includes a tire, and a wheel disposed on the tire. A space between the tire and the wheel is filled with a filler gas. The filler gas includes nitrogen gas having a concentration equal to or greater than a concentration of nitrogen gas in air, and hydrogen gas having a concentration of 0.5% or more. A concentration of oxygen gas in the filler gas is less than a concentration of oxygen gas in air.
Claims6
A method for producing a wheeled tire, comprising:
- filling a space between a tire and a wheel with nitrogen gas only or both nitrogen gas and oxygen gas, the tire being disposed on the wheel;
- injecting hydrogen gas, which serves as a reaction gas, into the space whose pressure has become suitable for traveling of a vehicle;
- and
- performing an inspection for a leak of the injected reaction gas from the tire disposed on the wheel,
- wherein a concentration of the injected reaction gas in the space is 0.5% or more.

A method for producing a wheeled tire, comprising:
- filling a space between a tire and a wheel with nitrogen gas only or both nitrogen gas and oxygen gas such that a pressure in the space becomes a pressure that is suitable for traveling of a vehicle in a case where the tire and the wheel are installed on the vehicle, the tire being disposed on the wheel;
- injecting hydrogen gas, which serves as a reaction gas, into the space after the space has the pressure that is suitable for the traveling of the vehicle in the case where the tire and the wheel are installed on the vehicle;
- and
- performing an inspection for a leak of the injected reaction gas from the tire disposed on the wheel,
- wherein a concentration of the injected reaction gas in the space is 0.5% or more.
