Overview

The RLB900+ is a wide-base all-position radial for trucks that carry heavy loads on mixed surfaces. Available in 385/65R22.5, 425/65R22.5, and 445/65R22.5, it uses a deep tread with large block elements and a heavy-duty belt package to handle high gross weights on and off pavement.

Why This Tire Matters

Wide-base tires on mixed-service trucks face a unique challenge: the large footprint that provides flotation and load distribution also creates more opportunity for penetration damage from off-road debris. The RLB900+ addresses this with large, solid tread elements that reduce the number of vulnerable groove areas and a belt package reinforced for impact resistance. For construction fleets, waste haulers, and heavy equipment transport — operations where payload weight and terrain both punish tires — this design approach makes a measurable difference in tire life.

Key Features

• Wide Base Design for High Payload Capacity — The broad footprint distributes weight — reducing ground pressure for better flotation on soft surfaces and meeting the load requirements of heavy vocational trucks.
• Deep Tread with Large Block Elements — Rather than many small tread blocks (which provide more edges but more vulnerability), the RLB900+ uses larger elements that resist chunking and tearing on rough surfaces while still providing adequate traction.
• Heavy-Duty Belt Package — The steel belt layer is reinforced to handle the impact forces and penetration threats that come with off-road and poor-road surfaces. Belt separation is a common failure mode in wide-base tires; this construction targets that weakness.
• All-Position Versatility — Rated for steer, drive, and trailer positions — simplifying tire inventory for mixed fleets that run the same tire across multiple axle positions.

Best For

Construction material haulers (dump trucks, tippers); concrete mixer trucks operating on job sites; waste collection vehicles; heavy equipment lowboy tractors; any vocational truck running high gross weights on mixed surfaces.
