When my truck was in a shop for installation of 275/75/18 K02's, I was told that one or more tires would require more than 10 oz of lead weights to be balanced and bag weights/balancing beads should be used. I have never heard balancing beads until that point and I was very skeptical and uncomfortable about putting bunch of beads inside my tires but I had no choice since that was the only option that was given to me. Then they also said that these large off-road tires are often manufactured unevenly and require using this type of balancing method. I got about 500 miles on my tires since the installation and I feel vibration at between 55 and 65 mph. It's pretty annoying when your steering wheel wiggles when you are cruising down the highway. I haven't noticed any vibration whatsoever when I was running Michelin LTX stock tires. Any of you guys running KO2's have balancing and vibrating issues such as mine? What are your thoughts on balancing beads?
