IRC Tires: A Century of Two-Wheel Expertise

IRC Tire, the consumer-facing brand of Japan's Inoue Rubber Co., Ltd., has been engineering rubber for two-wheeled machines since 1926. What began as a bicycle tire and tube manufacturer in Nagoya, Japan, evolved into one of the world's most respected names in motorcycle rubber. By 1952, IRC had expanded into motorcycle tire production, and by the mid-1960s the brand had established a foothold in the North American market — a presence it has maintained and grown ever since.

As a subsidiary of the INOAC Corporation, IRC operates manufacturing facilities across Japan, Vietnam, Thailand, Malaysia, Indonesia, and China, giving it the global scale to serve riders in virtually every market. Yet despite that international reach, IRC has never lost sight of what matters most at the point where rubber meets road: performance, durability, and precision engineering.

Built for Every Rider, Every Terrain

IRC's motorcycle lineup is one of the broadest in the industry. Whether you're threading through tight Trials sections, pinning the throttle in an XC/MX race, grinding out an Enduro stage, or simply commuting on a scooter, IRC has a purpose-built tire for the job. Their catalog spans off-road, enduro, trials, dual sport, street, mini moto, and scooter applications — a depth of coverage that reflects nearly a century of compound and tread pattern development.

Shoppers looking for the right rubber will find IRC's motorcycle tires cover everything from aggressive knobby off-road designs to road-focused touring profiles. IRC's commitment to quality control is built into every stage of production, with stringent testing ensuring that each tire delivers reliable grip, predictable handling, and lasting tread wear across a wide range of riding conditions.

The IX-Heavy Inner Tube Legacy

IRC's reputation extends well beyond the outer casing. The brand's motorcycle tire inner tubes — particularly the iconic IX-Heavy series — have earned near-legendary status among professional mechanics and serious enthusiasts alike. Known for their exceptional durability, these heavy-duty tubes are a go-to choice for off-road and enduro riders who can't afford a flat mid-trail. It's said that mechanics worldwide know to reach for the silver box when reliability is non-negotiable.
