Proper tire inflation pressure and loading are important factors to ensure riding safetyOverloading can lead not only to tire damage but also to loss of control Under-inflation makes it difficult to turn corner smoothly and results in premature wear of tires Over-inflation reduces tire's area of road contact and thus results in skidding and loss of control Do not interchange tires between wheels on the same vehicleDo not use tires of sizes and types different from the originally installed tiresRotation of tires or use of such different tires may adversely affect handling of the vehicle and can result in loss of control Replace the wheel if it is deformed or has cracks or scratchesAlso replace the wheel if its runout exceeds the service limit Replacement wheels must be equivalent to the originally installed wheels
