One or more inner walls are usually solid or complete (that is, not perforating) and are therefore airtight；And therefore will Compartment is divided into each sub- compartment of sealing.In other embodiments, at least one of circumferential wall may include perforation, to allow in machinery Load passes through gas between sub- compartment during (such as during riding) being applied on tire.

Tire is made of elastomeric material, such as vulcanized rubber.Sealed compartments can be filled with the gas optionally to pressurize (such as air) or vibration-absorptive material or the elastomeric material softer than tire material.

When cyclist rides over vehicle (such as bicycle) on rugged surface, because compartment deformation is (due to it Filled with gas or softer material), circumferential sealing compartment can be used as damper.When filled with uncompressed air or another bullet When elastomer material, tire is used as the tire of non-pneumatic tubeless (and/or without air), thus avoids the need for keeping closing in tire Suitable air pressure and/or the risk having a flat tire.

Circumferential inner wall provided for circumference ground bearing part support and be subjected to it is to load relevant, generally radially orient Compression.This compression reduces the impact being applied on tire in use, so that it is more smooth to make to ride.

Inner wall usually has the thickness between the 10% and 75% of the wall thickness of circumference ground bearing part.In some realities It applies in example, the thickness is between the 20% and 50% of the thickness of circumference above ground portion.

In other embodiments, the thickness of the first wall between circumference ground bearing part wall thickness 10% and 75% it Between.In some embodiments, the thickness is between the 20% and 50% of the thickness of circumference ground bearing part.This at least one Second circumferential wall can have thickness similar with the thickness of the first radial circumference wall, although in order to realize its function, Also it can have the thickness smaller than the thickness of the first radial circumference wall.

Tire may include two shoulder portions integral with tire body, and described two shoulder portions are substantially put down each other Row.These shoulder portions (it can be that disclosed in WO 2017/085709) surround the peripheral portion of the wheel of fit a tyre Point.These shoulder portions can be used for example as brake area.

The disclosure additionally provides a kind of wheel of tire including following types.
