OTR Engineered Solutions has expanded its popular SolidBoss® smooth skid-loader tire lineup with the introduction of a new 31×10-20 (10-16.5) size, providing customers with another flat-free solution engineered for demanding hard-surface applications.
The new tire assembly extends the reach of the SolidBoss family, giving equipment owners and fleet managers a durable, low-maintenance tire option for skid steers operating in some of the harshest environments, including demolition sites, recycling facilities, scrap yards, waste handling operations, and other applications where tire damage and downtime can significantly impact productivity.
SolidBoss smooth tire assemblies are specifically designed for maximum durability on abrasive surfaces such as asphalt and concrete. Unlike traditional pneumatic tires, the semi-pneumatic SolidBoss design eliminates flats while incorporating cushioning apertures that help absorb shock and deliver a smoother, more comfortable ride.

“The addition of the 31×10-20 size allows us to accommodate an even wider range of skid steers,” said Steve Jensen, VP National Accounts at OTR Engineered Solutions. “Customers have consistently asked for more flat-free options in this size category, and we’re excited to bring the proven durability and ride quality of SolidBoss smooth tires to even more machines and applications.”
In addition to its flat-free construction, the SolidBoss smooth tire features proprietary rubber compounds engineered to resist chunking, tearing, and slicing damage commonly encountered in severe-duty environments. The result is longer service life, reduced maintenance costs, and increased machine uptime.
Designed for quick and easy replacement, the new 31×10-20 assembly features an 8 on 8.0 bolt pattern, the most popular in the industry. It is now available through OTR’s extensive distribution network or online at otrb2b.com.
