Overview

When a fleet operates where the roads don't cooperate — monsoon rains in Thailand, muddy job sites in Nigeria, snowy mountain passes in Chile — the RLB1 is the drive tire that gets the load through. It uses an aggressive open-shoulder tread with full-depth siping, biting into loose surfaces while channeling water and slush out of the contact patch.

Why This Tire Matters

Closed-shoulder highway tires are efficient, but they're the wrong tool when traction matters more than fuel economy. The RLB1's open shoulder design creates the mechanical grip for loose, wet, and snow-covered surfaces. More importantly, the siping runs the full depth of the 26/32" tread — meaning the traction doesn't disappear as the tire wears. Goldtop customers in Southeast Asia's rainy-season delivery fleets and South American mountain routes consistently choose this tire when conditions dictate capability over fuel savings.

Key Features

• Aggressive Open Shoulder Tread — The open shoulder lugs bite into soft surfaces — mud, gravel, snow — while the wide voids self-clean at speed. You don't get stuck because the tread can't shed what it's picked up.
• Full-Depth Siping (26/32") — Most tires lose siping depth as they wear — the fine cuts are only in the top portion of the tread. The RLB1's sipes extend the full 26/32", meaning the tire grips almost as well at 50% tread as it does at 100%.
• Heavy-Duty Retreadable Casing — The casing is built with enough structural reserve to come back for retreading — a cost advantage that multiplies across a fleet running aggressive-drive tires that tend to wear faster than highway patterns.
• Tubeless and Tube-Type Availability — Available in both configurations, covering markets where tube-type wheels are still standard (particularly in Africa and parts of Southeast Asia) as well as modern tubeless setups.

Best For

Fleets operating in regions with heavy seasonal rainfall (monsoon climates); construction and logging trucks running on unimproved roads; winter-condition fleets that don't want dedicated winter tires; mixed on/off-road applications where traction trumps fuel economy; operators in markets still running tube-type wheels.
