Why not just get it done properly?
What's the definition of "properly"? If by properly you are referring to the lead weights, These pellets are pretty neat, and if they do what they claim they do, they're cutting edge technology. But I've never tried them.
Taken from their website:
Strictly for the Technical types, here's some info on why beads are more effective than rim-mounted weights.
There's no place to mount standard wheel weights other than on the edge of the rim. Problem is, that is not where the weight is most effective, for two reasons.
The weight is not centered across the sectional width of the tire. That's why some Tire Mechanics will split the weight into two smaller weights and put one on the inside, one on the outside. The most effective position is directly in the center of the tire, and this is where the beads always are located.
The other problem is centrifugal* force. Lets say, as an example, your 16" tire requires 3 oz's of weight, according to the Spin Balancer. The spin balancer is calibrated to calculate the amount of weight based on the placement of the weight at, in this case, an 8" radius. Once again, this is not the most efficient location for a counterbalance weight.
Continuing on with this example, the inside carcass surface ( next to the tread ) is about 4" farther away from the edge of the rim, to give us a radius of 12". This inside carcass surface is where the beads work, and the farther away from the center they are, the more centrifugal force they develop. So we can use this formula:
F1*R1 = F2*R2 to calculate the actual weight of beads needed.
(3)*(8) = (x)*(12)
24 = 12x
x = 24/12 or 2 oz.
So as we've shown, the beads are much more effective per oz than wheel weights, another reason to purchase Dyna Beads™! Stick-on weights are even worse, due to the fact that they have to be placed on the inside flat surface of the wheel, which is even farther away from the tread than the rim itself.
