OTR (Off-The-Road) wheels, also known as construction or mining wheels, are specialized wheels designed for use in heavy-duty off-road applications. These wheels are used on large industrial vehicles and equipment that operate in rugged terrains, such as construction sites, mining sites, quarries, and forestry areas. OTR wheels are built to withstand the demanding conditions of off-road environments and provide stability and durability for the vehicles they support.  Key features of OTR wheels include:  1. **Size and Construction:** OTR wheels are much larger than typical passenger car wheels, ranging from 15 inches to over 63 inches in diameter. They are generally constructed with robust materials, such as steel or heavy-duty alloy, to handle heavy loads and challenging terrains.  2. **Bead Design:** OTR wheels have a unique bead design to provide a secure and airtight fit with the tire. The bead design prevents the tire from detaching from the wheel during extreme off-road conditions and heavy load applications.  3. **Reinforcements:** OTR wheels may include reinforcements or stiffening features to enhance their structural integrity and prevent deformation or damage under extreme loads or impacts.  4. **Bolt Patterns and Spacing:** OTR wheels have specific bolt patterns and spacing to match the hub configuration of the vehicles or equipment they are intended for. This ensures proper mounting and fitment.  5. **Load Rating:** OTR wheels are designed with high load ratings to handle the substantial weight of large construction and mining vehicles, including dump trucks, loaders, bulldozers, and excavators.  6. **Corrosion Resistance:** OTR wheels are often coated or treated with corrosion-resistant materials to protect them from rust and deterioration caused by exposure to harsh environmental conditions.  OTR wheels play a crucial role in supporting the immense weight of heavy equipment and ensuring stability and traction in challenging terrains. Their robust construction and design make them well-suited for the harsh conditions encountered in construction and mining operations.  It's essential to use the right OTR wheels with proper tire combinations to maximize the performance, safety, and longevity of the off-road equipment. Regular maintenance and inspections are also necessary to ensure the wheels remain in optimal condition for safe and efficient operation in off-road environments.
