How is it that we balance the funnycar tires on a 50 year old bubble balancer. 34 inch dia and 17 inches wide. They go 250-300 mph and are smooth as glass except when they are shaking due to power application. Just a hand full of tape weights and a few feet of duct tape to make them stay on.
Granted they only last a couple of miles but I can assure you that at 250+ if there was an out of balance condition you would know it big time.
I've even checked them when they are worn out right before we dismounted them and they were right on balance. They are light weight for the volumn but they still weigh about what a dually tire weighs.
