Forerunner QH645. FEATURES AND BENEFITS: Upgraded controllability; Various terrain traction; Enhanced load durability; Better damage resistance; . OVERVIEW: The Forerunner QH645 is an all season tire made for tractors.The aggressive tread design and the durable rubber compound boost the tire's performance on versatile terrains. The optimized tread elements and a high void ratio improve the tire's soft and loose field and on-road traction. The ideal footprint enhances the performance, guaranteeing the tire's forward motion at all times. The tread manages to keep the footprint clean, by eliminating mud, snow, and rocks stuck between the tread elements. This greatly increases the model's driving safety levels on versatile terrains.The maintained surface contact greatly improves controllability. These tread elements allow the tire to optimize its contact with the field, boosting steering responsiveness and driving stability. Thanks to this the tire is able to enhance its steering response time and accuracy, while the structure is secured against driving pressure. This enables the tire to significantly increase its handling and maneuvering throughout the performance.By combining the tread design and the stronger casing the tire avoids damage. This is ensured with the durable compound and the ideal structure. Their combination helps to increase the tire's overall usability. They prevent punctures, impact damage, and cuts to the structure, while various tread damage is effectively prevented. As a result, it increases the tire's overall service life.The Forerunner QH645 offers great load and driving durability. Load durability is an important feature that the tire structure offers. The strengthened internal structure is able to withstand and carry larger loads with ease. As the tire keeps its optimal shape, it can safely handle larger loads. This increases the tire's better load capacity.This specific tire model features a BIASED ply construction.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.
