Kluhsman Racing Components will introduce its Tire Stagger Dyno. The dyno measures the diameter of a tire before it has been mounted. For circle track racing it can be used to maintain a tire at different pressure/circumference ratios to get different car stagger or for drag racing the dyno can be used to maintain the same stagger. The machine weighs 34 lbs. and measures the width from 8" to 12".8".
