I need to put a new rear tire on my V Star1100 Classic and have been checking the local tire shops to see who has the best deal on a Metzler 170/80/15 tire. Most want 180 or more for the tire then 40 dollars to mount and balance it , if I bring the wheel to them they want 80 bucks to pull the wheel off the bike and then mount and balance the tire and that price is only good if I buy the tire from them. Today I found a new shop that wants to get better known and they can get the tire for 150 and 25 dollars to mount it. I asked about balancing and they said they use Dyna Beads, they pour them into the tube or tire if it is tubeless. They claim there have been no problems but I have never heard of this. Does anyone know about dyna beads?
