The M325 is the cornerstone of our construction line. It provides full coverage for mixed service fleets serving the construction, mining, energy, and logging industries. A tough casing developed through several years of real-world testing in severe duty applications, an extra wide footprint with specially designed stone ejectors in every groove, and a cut-and-chip resistant tread compound deliver durability, retreadability and a high return on investment. M325 Wide Base tires are built to withstand heavier loads.
