Core Functions
Simplify tire assembly & removal
During fitting, the tire bead can rest inside the recessed groove first, then slide gently toward two rim flanges. This avoids overstretching beads against tall rim edges that cause assembly difficulty. It is especially critical for tubeless tires, which rely on air pressure to lock beads against flanges for airtight sealing - the groove drastically cuts fitting resistance.
Prevent bead dislodgement under low pressure
When tire pressure drops, lateral driving forces may shift tire beads. The drop-center groove temporarily locks beads in position, greatly lowering the risk of bead slipping and air leakage.
Compatible Equipment & OEM Brands

- Liebherr: Mining excavators, heavy wheel loaders
- Extra compatible brands: CASE, Bell, Belaz, Dressta, Hitachi, JCB Suitable application scenarios: open-pit mines, quarries, road construction, port logistics, large earthmoving projects, heavy trucks, passenger buses, sedans and light trucks.
Common Types and Characteristics
1. Deep Well Rim
- Structure : The groove is deep, with symmetrical rim heights on both sides and a narrow groove bottom width.
- Features : Single tyre installation is convenient, as the tyre can be slid into the groove from one side without removing the hub, and then inflated to expand the tyre bead to the rim position.
It is primarily suitable for small vehicles, sedans, and light trucks.
2. Flat Base Rim with Well
- Structure : The rim bottom is flat, with the groove located on one side, and the outer flange height is slightly higher than the inner flange.
- Features : It can accommodate both tubeless and tubed tyres. The flat-bottom design is suitable for heavy-duty vehicles such as trucks and buses. The groove assists in tyre bead positioning.
Some heavy-duty rims have shallower grooves, primarily to provide operational space during tyre installation and removal.
3. Split Rim
- Structure : The rim is divided into two halves connected by bolts, with the groove located at the joint surface.
- Features : It is a disassemblable rim, facilitating the installation of extra-wide tyres or special-specification tyres, such as those used in construction machinery.
Sealing relies on bolt tightening and sealant; improper installation may cause air leaks. It is currently primarily used in industrial vehicles.
