I usually agree with function over form, except in this instance.
Nothing irks me more than seeing globs of lead plopped on the lips on nice wheels. I've always used static balances (versus dynamic) on all my vehicles and have always been pleased with the results. I get far more than the expected lifespan from my tires.
If a tire simply can't be balanced with a static balance and MUST be balanced dynamically, you may have larger issues (just my personal experience) with the tire and/or rim.
Technically speaking I know that a dynamic balance is superior to static; however, if I get far more mileage out of my tires than expected from the manufacturer, never have balancing issues, and don't have to see those ugly *** weights...whats the loss?
