BTW I have aluminum wheels on my trailer and I noticed they don't have the normal lip found on normal steel or auto rims. Can these be balanced?
Flyrotor, my friend in Canada invented a system to inject a balancing material through the valve stem on truck tires. The material flows inside the tire and continually balances the tire from the inside. I don't know if it ever took off. I need to ask him if it would work for my trailer tires now that I think about it. Maybe he worked on this because most do not balance, so I could be wrong. I know he talked about how much labor was involved in removing and balancing 18 tires![/QUOTE]
Yes they can put weights on them and in most cases they are made specifically for the aluminum rims. The gap is larger to accomodate for the larger lip.
The product you are talking about is called Dynabeads. They are small glass beads in a solution that gets poured in through the valve stems, then driven and it works on it's own lining the inside of the tire to balance it out.
There is another product that is used on duallys which is mounted on the inside of the rim between the brake rotors and the rim. It is a round tube that has silicone with bearings in it and while driving the beads balance out the tires automatically adjusting to the tires needs. These are vehicle specific designs and they make them for large semis as well. This eliminates the need to balance every tire.
