^ have tried the balancing beads on my Dakota with mud tires was a waste of money for me just the moisture in the air was enough to make the all stick together on one spot in the tire as far as the spark plug go if you have a few hand tools and a couple of hours you can do it your self

 

ive never seen or head of balancing beads, i think i will look into that. as for the plugs, i havnt changed plugs since my 88 camaro where they were right there on top and all i need was a spark plug socket haha. i dont want to go taking crap apart on my truck because ill probably cause more problems then good.

 

These are the beads I used and bought them off ebay with the application bottle to put them in the tire

just did some research on dynabeads, looks interesting but was not really recommended by the website for use on lower profile applications. would like to know if anyone has used it on them

 

Yeah I used them because I run them on my all terrains on my 24s which are heavy obviously.

Your best bet is to ave them road force balanced and not a slow speed balancer like most shops have.
