Overview

The RR4 is a no-compromise mixed-service all-position radial built in a single 12.00R24 size with a 20-ply tube-type construction. It uses large open grooves and aggressive shoulder lugs to handle the worst conditions a vocational truck encounters — from muddy construction sites to rock-strewn access roads.

Why This Tire Matters

The 12.00R24 size class serves a specific segment: heavy vocational trucks — often older equipment — operating in severe conditions where tire failure has real consequences. A stranded concrete mixer on a job site isn't just a tire bill; it's a pour that might set up in the drum. The RR4's large groove design clears mud aggressively, and the heavy-duty casing is built for the impact loads that come with off-road work. Goldtop supplies these to construction fleets in Africa and the Middle East where 12.00R24 remains a common specification for mixed-service vocational trucks.

Key Features

• Large Open Grooves with Aggressive Shoulders — The wide groove channels self-clean at low speed, shedding mud and debris rather than packing up and losing traction. The aggressive shoulder lugs provide lateral grip on loose surfaces.
• 20-Ply Heavy-Duty Casing — Built for the weight and impact forces of loaded vocational trucks on rough terrain. The casing is designed to survive the first life and come back for retreading.
• On/Off-Highway Capability — The tread pattern balances off-road traction with acceptable on-road wear characteristics, so the truck can move between job sites at highway speeds.

Best For

Heavy vocational trucks in construction and mining support; concrete mixer fleets; dump truck operations in severe conditions; fleets running 12.00R24 tube-type wheels.
