Alliance Tire Group presents the new diagonal Alliance 321 Plus R-4 along with new dimensions for the Alliance 585 range

Alliance Tire Group presents Alliance 321 Plus, a new series of heavy-duty tires for backhoe loaders and compact front-end loaders. Thanks to its remarkable tread depth, robust design, wide lugs and heat resistant compounds (Hrc), the new diagonal R-4 range premium product features increased traction, higher damage and wear resistance as well as improved durability. The use of special compounds allowed Alliance Tire Group developers to focus on tread design. The result was a significantly high tread pattern with an accentuated anti-slip tread pattern. The wide lugs were chosen to improve resistance to cuts, tears and impacts, while the narrow gaps prevent stones from getting stuck in the lugs during use. Alliance 321 Plus was originally developed to work in warm to hot climates typical of regions such as the Middle East, Africa or India using heat resistant compounds. Alliance 321 Plus is available in sizes 12.0/70-16, 12.5/80-18, 15.5/60-18 and 17.5/65-20 as well as 380/80-24 (14.9-24), 440/80-24 (16.9-24), 480/80-24 (18.4-24), 480/80-26 (18.4-26) and 440/80-28 (16.9-28). News also for the Alliance 585 series. The steel belt tire was designed to adapt to hard surfaces as well as gravel and loose terrain, offering maximum versatility in demanding conditions. The special tread design and robust construction make it suitable for use in construction, industry and public services, besides goods handling and agriculture, with a B (50 km/h) speed rating. Alliance 585 is now available in five new sizes.
