Protect your self-steering axles with the RHINO Self Steer Guard — engineered for tight turns, rough roads, and long-term reliability. Available in plastic, stainless steel, and aluminium for 11R, low profile, mega single, and 19.5” tyres.
Built for Turning. Designed for Protection.
Modern trailers demand more from every component — especially self-steering axles. These systems improve manoeuvrability, reduce tyre wear, and support productivity schemes like PBS (Australia) and HPMV (New Zealand). But they also introduce new challenges in guarding.
The RHINO Self Steer Guard is a purpose-built mudguard designed with a flat-top profile, allowing steering wheels to rotate freely without striking the guard. That’s the key difference — and it means fewer failures, less downtime, and better protection for your steering system.
Tyre Compatibility
The RHINO Self Steer Guard is available for the four most common steering axle fitments:
- 11R 22.5″
- Low Profile (e.g. 275/70R22.5)
- Single (e.g. 355/65R22.5)
- 19.5″

- Available in 2mm ribbed.
- Rolled 4mm edges (35mm depth) for strength and spray suppression
- Curved corners and reinforced ends for durability and easy installation
Purpose-Built for Compliance and Productivity
Self-steering axles play a critical role in vehicle performance and compliance.
According to Driving Tests (TR Group):
- Improve turning circle — essential for NZ’s 25m limit
- Reduce tyre wear by up to 4 tyres per 100,000 km
- Improve fuel economy by up to 1%
The RHINO Self Steer Guard supports these benefits with a flat-top design that:
- Reduces likelihood of guard damage when turning
- Supports compliance with wheel guard regulations, e.g. PBS- and HPMV-aligned design for trailers requiring full steering range
