Forerunner QH611. FEATURES AND BENEFITS: Versatile terrain traction; Upgraded controllability; Improved load durability; . OVERVIEW: The Forerunner QH611 is an all season tire made for tractors.Consistent road contact boosts the tire's overall controllability. Maneuvering is upgraded with the directional tread design's optimized elements. The sipe and groove placement generate friction when stopping, which significantly shortens the overall braking distance. Additionally, the shoulder blocks generate biting edges to increase their cornering ability. Maintaining road contact helps to enhance the tire's steering responsiveness and driving stability. This helps to improve the driver's control over the vehicle throughout the drive.This model offers exceptional damage resistance. The strong ply construction protects the tire from punctures, cuts, and other external damage. As they are unable to damage the casing, they do not shorten the service life. In other words, they significantly boost the tire's overall usability. The robust structure and the rubber compound increase the tire's heavy-duty performance. Tires can deform under load pressure if their construction is not strong enough. Therefore, by reinforcing the sidewalls of this tire, it is able to securely handle larger loads. Great load capacity is ensured as the tire manages to increase its ability to carry and withstand such loads.This Forerunner QH611 promotes great different terrain applications. The ideal tread design enables the tire to improve traction on soft, loose, and uneven terrains. The optimized tread elements allow the tire to significantly upgrade forward motion on various terrain surfaces. The high void ratio keeps the footprint clean by dispersing mud and snow from the footprint, preventing them from blocking the surface contact. This also avoids stone retention from harming the casing, promoting better driving safety levels.This specific tire model features a BIASED ply construction. There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.This is a Tubed Type Tire (TT), which requires an inner tube to properly function. This purchase does not include the inner tube or flaps.The Overall Diameter or O.D. advertised represents the tire's overall diameter in inches, once the tire has been properly inflated and mounted per the manufacturer's recommendation. This advertised number is provided to Priority Tire by the tire manufacturer.Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
