I think its BS. I worked with tires and anything inside peoples tires is NOT a good idea. Im not going to fully explain now why it wont work, but if you wanna try it out, go put some water in your tires. same general idea.
TECHNICALLY THIS IS NOTHING NEW!!! IT HAS ACTUALLY BEEN AROUND SINCE THE MID 80'S!!! 18-WHEELERS HAVE USED IT SINCE THEN. I CAN VOUCH FOR THIS BECAUSE MY DAD OWNS HIS OWN TRUCKING COMPANY AND THEY HAVE ALWAYS USED THIS TYPE OF BALANCING. IT IS DEFINITELY NOT BS!!! IT EXTENDS THE LIFE OF 18-WHEELER TIRES BY ABOUT 75K MILES. FOR CARS IT EXTENDS THE LIFE BY ABOUT 20K MILES. I HIGHLY RECOMMEND IT MYSELF...AND WILL SWEAR BY IT...
well, just put them in... and pq pq pq pq pq viberations are horrible!!!!!!!!!!!!!
gonna take them tomorrow, have them taken down, re mounted and static balanced, and ill deal with the very tiny lil vibration at 60-75
