Chumbley’s is proud to say we are one of very few shops in the Central Iowa Des Moines Metro area that operates a Hunter Road Force Tire Balancer. Why a road force? This is the only machine that dynamic balances the tire. It measures the spring rate of the sidewall of each tire, and then tells the operator where to place when installing on the vehicle. It will pick up faulty or failing tires. Call us today to have your tires Road Force Balanced.
