This kit contains 4-ounces of Dyna Beads, pre-loaded in BestRest's exclusive Dyna Hose. There's enough beads in the hose to balance 2 "typical" tires. The hose is marked at 1-ounce intervals so it's easy to tell how much you've put in the tire.
We're often asked if it's a problem to have "too many" beads in a tire. Yes, too much of a good thing can result in vibration. Follow the chart for best results, but from our experience a SMALL amount of extra beads won't hurt anything.
-Smaller bikes generally require 1 ounce in both the front and rear tires
-Medium-to-large bikes generally require 1 ounce in the front and 2 ounces in the rear
-Large bikes (full touring bikes) generally require 2 ounces in front and rear
-Try to follow the recommendations listed below. Not having enough Dyna Beads in the tire can result in an unbalanced tire because there won't be enough beads to offset the inherent wheel imbalance.
Tire Width - Recommended oz. per tire
80-130mm wide (typical front) - 1
140-230mm wide (typical rear) - 2
Gold Wing (or heavy bike) - 2
10" diameter scooter or ATV - 1
12" diameter scooter or ATV - 2
As with most things in life, use common sense and don't dump a bunch o'beads in the tire without first consulting the recommendation chart. It's more likely that you might not have ENOUGH beads in the tire. Too few and the tire won't self-balance because there's not enough beads to counteract the tire imbalance. Too many beads and the tire can vibrate.
If you have a tire pressure monitoring system on your bike, don't worry. The Dyna Beads won't interfere with the system or damage it in any way. Dyna Beads don't thicken or harden over time like messy liquid balancing medias. And when you need to repair a puncture they don't interfere with plugs or patches.
One quick and easy way to install Dyna Beads is to use an air hose with a nozzle. Attach the Dyna Hose to the valve stem, put the air nozzle on the other end of the Dyna Hose, and give it a short blast of air. The beads will move thru the valve stem and into the tire. Control the amount of beads with the air nozzle. Using this method takes only a few seconds. This method doesn't work with every style of valve stem (tubes and rubber valve stems seem to have a smaller air passage), but when it does it's a real time saver.
