Overview

The RT500 is a 5-rib all-position radial in a low-profile configuration, built in sizes from 8.25R15TR to 285/70R19.5 — the broadest size range in DoubleCoin's all-position lineup. Special tread compounds handle high-scrub applications, and the steel belt package provides casing durability across steer, drive, and trailer positions.

Why This Tire Matters

The RT500's size coverage — from small 15" trailer sizes to 19.5" medium-duty truck sizes — makes it the tire that can follow a single specification across an entire mixed fleet. This is particularly valuable in developing-market operations where a fleet might include everything from 3-ton delivery vehicles to class 6 straight trucks. The 5-rib design provides stable handling in the steer position while the compound handles the scrubbing forces of drive and trailer use. For Goldtop customers managing diverse vehicle fleets across Southeast Asian and African markets, the ability to stock one tire model for multiple vehicle types reduces inventory costs and simplifies tire management.

Key Features

• 5-Rib All-Position Design — The rib pattern provides the handling stability needed for steer axles while maintaining adequate traction for drive and trailer use. True all-position versatility across the fleet.
• Special Tread Compounds for High-Scrub Applications — The rubber formulation resists the accelerated wear that comes from constant turning, braking, and acceleration in delivery and regional applications.
• Steel Belt Package for Casing Strength — Steel belts provide the structural foundation for durable, retreadable casings — extending the value of the tire investment across multiple lives.
• Extensive Size Range (15" to 19.5") — Coverage from small trailer sizes through medium truck sizes, enabling fleet-wide specification with a single model.

Best For

Mixed fleets with diverse vehicle types seeking tire specification consolidation; developing-market operations where procurement simplicity matters; P&D and regional delivery fleets running medium-duty trucks.
