When balancing a tire, is it ok to stack sticky weights on top of each other?
Also, should you remove the old weights and spin the tire or is it ok to spin the tire with the old weights and just add if needed? What if it needed less than .50oz with the old weights?
don't stack them

Each rim has a moment of inertia that is slightly different from one rim to another because of a myriad list of minute defects that accumulate as the rim is manufactured. The moment of inertia in layman's terms is the effect of a 0.25 kg weight at the rim of the tire vs. the same one slightly closer to the hub. The moment of inertia is not the same, it's slightly less. Use the exact counterweight for your new tires, and leave it at just one counterweight. (Moment of inertia in an unbalanced rim starts to "hop" up and down as you drive at high speed because it's not been neutrally balanced, there's more mass on one side than the other).
