Overview

The RR150 is a 5-rib steer and all-position radial with a 19/32" tread depth, wide groove channels, and channel siping for wet-road confidence. It's built for fleets that run in varied conditions and need a steer tire that handles rain as well as it handles dry pavement.

Why This Tire Matters

Steer tire hydroplaning isn't just a wear issue — it's a safety issue. The RR150's five-rib design with wide circumferential grooves channels water out of the contact patch efficiently, maintaining road contact in heavy rain. The channel siping — fine cuts within the ribs themselves — provides additional biting edges for wet braking and cornering. For fleets in Southeast Asia's monsoon regions or equatorial Africa's year-round rainfall zones, wet-weather performance isn't optional. Goldtop customers in these markets report the RR150 earning its keep during rainy season when lesser steer tires lose grip.

Key Features

• Five-Rib Wide Groove Design — Five continuous ribs with four wide channels between them. The number of channels and their width determine how much water a tire can evacuate per second at speed — and the RR150 is designed for heavy rain.
• Channel Siping for Wet and Dry Traction — The fine transverse cuts within each rib create thousands of small edges that grip wet pavement. They also help the tread run cooler by increasing surface area for heat dissipation.
• Deep 19/32" Tread for Extended Life — Steer tires typically wear faster on the shoulders due to cornering forces. A deeper starting tread provides more rubber to work with before the tire reaches the wear indicators.
• Multi-Use Versatility — While optimized for steer position, the RR150 also performs on drive and trailer axles for fleets that prefer to standardize across positions.

Best For

Regional and highway fleets in high-rainfall regions; mixed fleets seeking a single all-position tire specification; operators prioritizing wet-weather safety without sacrificing tire life.
