Pr1mo Orion Solid 24 x 1 3/8 wheelchair tires

Last updated: 5 October 2026

The Pr1mo Orion Solid has the same full profile and street tread as a pneumatic 37-540 tire, but it is moulded from solid polyurethane. There is no tube and nothing to inflate, so it cannot go flat. The trade-off, as with any solid tire, is a firmer ride and more effort to mount. It is black and sold as a pair.

Pr1mo Orion Solid 24 x 1 3/8: common questions

Does it need an inner tube?

No. It is solid polyurethane and replaces both tire and tube.

Is the ride harder than air?

Solid tires generally feel firmer than pneumatic ones. A cushion and correct wheel setup help.

Is fitting difficult?

Solid tires are tight on the rim. Many buyers have a dealer or workshop mount them.
