Key Features
- OEM-Specified Construction — A genuine Genie tire built to the exact 315/55D20 diameter and 12-ply load rating called out in the original equipment specification, delivering the structural integrity these heavy-duty articulating booms demand.
- Direct Wheel Fit — Sized and beaded to mount directly onto the factory wheel rim of Z-45/25 series booms, seating correctly without rim adaptation or spacer work.
- Broad Z-45/25 Series Coverage — Fits the Z-45/25, Z-45/25J IC Power, and Z-45/25 IC articulating boom variants, making this the right tire across the core Z-45/25 family.
- Traction and Stability Under Load — The 12-ply rating supports the substantial gross vehicle weight of a loaded articulating boom, maintaining grip and lateral stability on rough or uneven terrain where these machines operate.
- Safe Travel and Positioning — Proper tire condition is critical on a self-propelled boom lift. A correctly inflated, structurally sound tire maintains the machine's stability envelope during travel and platform positioning, supporting safe operation within the manufacturer's rated parameters.
A tire on an articulating boom lift does more than support weight — it is a primary element of the machine's stability system. The 315/55D20-12 Ply sizing is engineered to carry the combined weight of the machine, operator, and materials while providing the contact patch and sidewall rigidity needed on rough or uneven ground. When a tire wears unevenly, develops sidewall damage, or loses structural integrity, it can compromise the machine's leveling behavior and overall stability during travel and elevated operation. Replacing a worn tire with the correct OEM part restores the original load-handling characteristics and keeps the machine performing as designed.
