OTR adds new size to SolidBoss smooth SSL tire lineup
Semi-pneumatic SolidBoss tires deliver reliable operation in harsh environments, including demolition sites and scrapyards

OTR Engineered Solutions has expanded its SolidBoss smooth skid-loader tire lineup with the introduction of a new 31x10-20 (10-16.5) size, providing customers with another flat-free solution engineered for demanding hard-surface applications.
The new tire assembly gives equipment owners and fleet managers a durable, low-maintenance tire option for skid steers operating in harsh environments, including demolition sites, recycling facilities, scrap yards, waste handling operations, and other applications where tire damage and downtime can significantly impact productivity.
Features of the new SolidBoss smooth tire for skid-steer loaders
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 cushioning apertures help absorb shock and deliver a smoother, more comfortable ride.
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 31x10-20 assembly features an 8 on 8.0 bolt pattern, which is popular in the industry.
"The addition of the 31x10-20 size allows us to accommodate an even wider range of skid steers," said Steve Jensen, vice president of 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."
