Ironhead represents one of the most technically advanced tire manufacturers in the market today. They produce a wide range of tires for all tastes and needs with a focus on commercial branch. For example, one of the most highlighted models from their lineup is the IAR221. At first glance, the name model is just some characters, but in fact, it is not like that. Let's get to know what they mean.
- I =is the manufacturer, Ironhead.
- A =means all position tire.
- R =reflects the regional application of this tire.
Above all, Ironhead IAR221 is produced at one of the finest production facilities in the world. It is the result of years of research and design that rivals that of the industry’s premium tires. It uses a wear resistant rubber compound shaped into an optimized pattern. Closed shoulders work in tandem with square-shaped center blocks to improve year-round performance. A wide footprint with closed shoulders creates high resistance against lateral forces and incorrect wearing. On the other side, specialized tread improves the road noise generated at high speeds and uneven surfaces. While the advanced sidewall compound with strong casing ensures enough durability and carrying capability.
In addition, the pattern incorporates four circumferential groves with a zigzag design. These are responsible to expel efficiently water, slush, snow, and mud from under the tire's footprint. Therefore, it proves great performance in all weather conditions without compromising the mileage. Plus, the Ironhead IAR221 is built in a wide range of 12R22.5 and 315/80R22.5. For example, the first size has 16-ply construction, while the second one is available in both 18 and 20-ply versions. As a result, it can serve a wide range of regional and freight trucks, local and interstate buses, but also dump trucks.
