So I ordered tires yesterday and found out that tire beads exist. Apparently they balance the tire as it is spinning. Do these actually work? or anyone have experence with them
Yes, that is how they work. As the tire spins the balancing beads orient themselves automatically to balance out the tire/wheel.
I replace the rear rubber on my AK myself and used Dyna Beads balancing beads. Was on Interstate for a short time running about 70+ mph during my ride yesterday, and a lot of 55+ mph and some 65+ mph road for just over 100 miles total for that ride. The beads worked great. Could not tell any difference from when weights were used. Just make sure you use the right amount and don't spill any. Due to the factory TPMS on my tires I couldn't put them in through the valve stem so had to pour them into the tire before seating the bead... IOW, spoon one side of the tire on the rim, then pour in the beads, then spoon the second side on the rim, and while keeping the valve stem up (as in not at the bottom) air up the tire to pop the tire bead on the rim.
I figure if they were not working it would show up on the Interstate.
