OTR Heavy Truck Construction Machinery Wheel Two-Piece Rim OEM Color Custom Impact Resistant 24-8.50/1.7 Fits 12.00-24 Tire

Product Description

What you are buying

A two-piece steel rim in 24-8.50/1.7. Two parts, not three: the pressed base carries the load, and a separate flange ring locked in place keeps the bead seated. There is no sitting ring in this build, so do not expect the field-strip routine you would use on a three-piece wheel. If a supplier hands you this size described as three-piece, that is a different wheel.

 

 

The steel and how it becomes a rim

We start with Q235B or Q355B plate, depending on the duty you describe. Pressing forms the shell, then robot CO2/MAG welding closes the seam. The flange is where these wheels usually fail in the field, so that region is built thicker rather than relying on a paint claim to sound tough. Before any coating, the bare steel is blasted clean - a smooth painted surface over mill scale chips off the first time a stone hits it, and we would rather not sell that.

Coating is your call on colour; give us a number or send a chip. Prime is standard. If a weld matters to your application, ask and we will photograph it before shipping.

 

This rim takes 12.00-24, bias or radial, tube type, with a 5° tapered seat. We fit this size most often on wheel loaders, dozers, motor graders and quarry dump units; on highway trucks the same shell shows up in low-speed or yard duty. Tyre inflation limits are set by the tyre maker and the vehicle builder, not by us, so treat the nameplate on your machine as the authority. Send your operating pressure and load case and we will tell you honestly whether this rim is the right one.

PCD and stud holes, offset, valve hole and tyre inflation hole, spoke plate design, colour, marking and packing are all produced to your drawing or sample. Non-standard sizes can be discussed; tooling is developed in-house.

Samples and trial orders supported. Drawings and technical data sheets are provided before production; every batch is shipped with inspection records. Export packing on strong steel pallets or in cartons with VCI anti-rust film, container loading arranged for full-cargo delivery.

Bolt circle, offset, pilot, valve and inflation hole positions, spoke-plate interface, marking, pallet layout - all movable, because the tooling is ours. Non-standard widths are possible; some need new dies, and we will say so in the first reply rather than after you commit.

Q: Is the 20-8.50/1.7 a tubeless rim?
A: No. It is a tube-type (with inner tube) multi-piece rim designed for 16.00-21 bias tires. If you need a tubeless (deep-base) rim in this size, we can also develop a custom design solution for you - send us your tire specification and hub drawing.
Q: What vehicles use 20-8.50/1.7?
A: It is typically fitted to off-road mining dump trucks, heavy tippers and earthmoving machines that run 12.00-20 tires. Because the same rim size can appear on different hubs, we always confirm fitment against your drawing or a photo of your current wheel.
Q: Can you supply just the rim body, or do I need the full set?
A: Both. We can supply the complete two-piece set (rim body + bead seat band) or individual components as spares. Lock rings and seat bands are also sold separately.
Q: Do you weld the rim to a disc?
A: Yes. If you provide the disc drawing or sample, we can deliver a complete welded wheel assembly, saving you the matching work on your end.
Q: What's the MOQ?
A: Custom orders start from 1 piece. Volume orders receive tiered pricing.
