Don't know about using the beads in the truck tires. I started this yr.using dyna beads in both my m/c bikes,GW 1500 & FJR 1300, like the way they make for a smooth ride. I have noticed that when I first start riding a little different
feel until the beads start to spread out,about 1/4 mi or so after that a nice smooth ride and less cupping on the front tire. I will be using the dyna beads in the truck next.

 

I added 8 oz antifreeze to each of the four tires. Will post in six months to say how they are doing.
