At 100 kilometres per hour, an average-sized tyre rotates 850 times per minute. Due to this, even slight variations in wheel balance, sidewall stiffness or roundness of the tyre can cause the wheel to physically slam into the road surface 14 times per second.
Modern high-performance vehicles and SUVs with large tyres are extremely sensitive to wheel, tyre and surface feedback, manifesting in poor ride quality and annoying vehicle vibration. Excessive wheel vibration can also result in accelerated tyre wear, and damage to suspension and steering components.
