This post is very interesting as are the others related to tire balancing and the use of dynabeads.
I just finished installing a set of Metzeler 888's with my new No Mar tire changer. My old front tire had 3.5 oz of weight and the rear had 1.25 oz. Never had any problems, but TN commented to me at Ribfest that I might have a problem with my wheels since that much weight was required. So when I removed the old tires I decided to check the static balance of the wheel itself. Interesting to find that the true heavy point on both wheels was not anywhere near the valve stem. Common practice to align dot on tire (light point) with valve stem (heavy point) on wheel when mounting tire, then balance the assembly. Attached pic shows this point was about 90 degrees off on front wheel.
I marked the true heavy point, mounted tire and aligned dot on tire with the true heavy point on wheel. I needed less than 1/2 oz weight on front and less than 1/4 oz on rear. Actually debated with myself for 10 minutes on putting any weight on rear as it was that close to perfectly balanced without any weights.
Takeaway here is that you should balance the wheels first and then the wheel with tire to minimize or even eliminate the use of weights regardless of method preferred. This may be why factory bikes have no wheel weights installed? For those with new bikes and no weights, see if the dot on the tire is aligned with the valve stem.
I'm also considering using dynabeads in the future. Since this was the first time I've installed and balanced my own wheels and tires, I went conservative. There are many other factors to consider with dynabeads; have to mount tire without tire lube grease (beads will stick), inside of tire must be dry and smooth and then how much do you use? For my tires, it's 2 oz per tire, but do you put in the whole 2 whether you need it or not? For example, why should I put in 2 oz when I only need 1/2 oz to balance?
Btw, I'm really happy with the No Mar product and glad my buddy TN convinced me to buy one. There are a few tricks of the trade to learn, but once you get it, changing your own tires is a breeze. Best of all, it's done right!
