Forerunner QH500. FEATURES AND BENEFITS: All season performance; Improved controllability; Upgraded load durability; . OVERVIEW: The Forerunner QH500 is a highway terrain, all season tire manufactured for trailers. This tire is NOT MEANT TO BE MOUNTED ON LIGHT TRUCKS, as its construction will not support the weight and performing style of such vehicles. It can ONLY BE MOUNTED ON TRAILERS.The model offers excellent controllability during the performance. The ribbed tread pattern manages to maintain road contact at all times. It increases steering responsiveness and driving stability. The steering response time becomes faster and more accurate to the towing vehicle's commands, while the structure is secured against driving pressure. At the same time, the outer ribs boost cornering and maneuvering. This combination guarantees a secure driving experience.The ideal tread pattern and the all season compound enhance the tire's year-round performance. In this manner, the ribbed tread pattern follows the road surface in dry, wet, and winter conditions, while the all season compound maintains rubber flexibility in changing temperatures. The optimal grooves help the tire to eliminate water and slush from the footprint in wet situations. They prevent hydroplaning, which avoids slipping in wet conditions. These elements enable the tire's safe year-round performance.The Forerunner QH500 offers excellent load and driving durability. The reinforced internal structure and the special silica compound maintain optimal tire shape under load and driving pressure. These elements enable the tire to carry and withstand heavy loads. As a result, it increases load capacity, making this tire perfect for trailer applications.This is a bias ply or diagonal tire. Due to the tire's internal construction and size, it is possible that the tire will look deformed. Smaller diagonal tires do not have reinforced constructions that can keep the tire from deforming. The bias construction and the small tire's non-reinforced internal structure allow the tire to fold in when it is deflated or not properly inflated. This is not constructional damage or an issue; it is a normal occurrence with such tires. In such cases, the tire needs to be mounted and inflated to the proper PSI or, in some instances, an inner tube needs to be added. The proper PSI and the inner tube are able to maintain the tire's ideal shape, preventing the bias plies from looking deformed. This ensures their performing safety and durability.The photo is a representation of the tire's possible deformation, it does not represent the specific tire model, size, tread pattern and application.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.
