The balance bead websites state that low profile tires cant be balanced with beads. But I guess you didnt read it.
Dyna Beads® with Low Profile Tires. You will note that we do not market to cars, SUV’s or personal minivans, mostly due to low profile, low aspect ratio tires. If you have low-profile tires, that being any tire with an aspect ratio 65 or below, you may have balancing issues that precludes using Dyna Beads as the sole balancing method. Our official policy is that we do not advise using Dyna Beads in any car, truck or SUV tire with an aspect ratio 65 or below unless used in conjunction with weights.**The reason for this is that this type of tire has a higher incidence of lateral imbalance, which is basically that one side of the tire is heavier than the other side,creating a “wobbling” effect, or “shaking” of the steering wheel. This type of imbalance can only be corrected by careful placement of traditional weights on the wheel rim.
Spyders should only be balanced with traditional stick-on lead weights. No beads. And especially NO LIQUIDS!!! If you put liquid in your tires, your dealer or mechanic who puts your next set of tires on, will charge you double for making a mess of his tire machine. DON"T DO IT!
