Company Overview
Backed by 16 years of tire industry expertise across both manufacturing and global distribution, GREAMARK CO., LIMITED is an independent OTR tire brand and provider of all-steel radial off-the-road tires for mining, construction, port handling, and heavy industrial equipment.
Our tires serve off-road dump trucks, rigid and articulated haulers, wheel loaders, dozers, graders, all-terrain cranes, port machinery, underground mining equipment, and other severe-duty applications.
GREAMARK engineers solutions around the realities of the job site: extreme loads, abrasive terrain, sharp rock, thermal buildup, extended operating hours, and non-stop duty cycles. We match every recommendation to equipment type, load profile, haul-road conditions, and operating intensity — so you get the right tire, not just any tire.
We partner with global distributors, fleet operators, contractors, and end users through durable products, flexible OEM/ODM programs, responsive field support, and dependable long-term service.
Brand Story
The GREAMARK story began with a clear understanding of the OTR tire market: customers need more than strong tires — they need reliable tire solutions that can perform under heavy loads, harsh terrain, long working hours, and unpredictable jobsite conditions.
The name GREAMARK comes from “Great Mark.” It represents our commitment to making a strong and reliable mark in the global OTR tire industry. Every GREAMARK tire is developed around real working conditions, from mining roads and quarry sites to construction projects, port handling areas, and heavy-duty industrial operations.
Driven by the spirit of “RUN OVER THE TOUGH,” GREAMARK stands for strength, reliability, and long-term cooperation. We focus on all-steel radial OTR tires built to support stable traction, cut resistance, heat resistance, wear performance, and dependable operation in demanding environments.
For GREAMARK, a tire is not only a product. It is part of the customer’s equipment uptime, operating efficiency, and daily productivity. That is why we continue to provide durable tire products, flexible OEM/ODM solutions, and responsive technical support for global distributors, fleet operators, contractors, and equipment users.
