First off there is only ONE supplier of certified ceramic Dyna Beads for balancing tires. The company's name is Innovative Balancing
in Rochester NY. There are many knock-offs being sold including people that will use all sorts of BB's inside their tires but I chose to use the certified authentic product and they have been in my tires since 2010 without having ANY problems.
Here is their link to the FAQ page
which you can read through to answer any questions about this product that you may have. If there is still some unanswered questions just give them a call and they will answer them for you.
Also, don't be fooled into installing Equal Powder or ANY other type of powder as that product has nothing to do with balancing beads, it is POWDER and once you have any moisture inside your tire it will cause the powder to cake up and then you have real problems.
As for the micro sidewall cracks with the Michelin tires, this is a common problem with certain models and sizes of Michelin tires. Mine have been cracked for years now but will be replaced this summer before leaving on our western NP tour as they were put on in April 2010 so they are close to 7 years old.
Time to change out those Michelin tires for something else.
