my brother was telling me that if you put anti freeze in your tires it will help in balanceing them. any one heard of this and if so how much do you use and how do you get it in the tire?

Most anti-freeze, with the exception of the bio-friendly ones are made from a petroleum byproduct, ethylene glycol. Petroleum and rubber do not mix, petroleum products soften rubber and break it down. I would say this is most likely bullshit.:flipoff2:

Anti-freeze breaks down over time and becomes acidic that's why it eats seals when you don't change it enough. I'd say bullshit and how could it be different than water in there. Use the weights keep it simple there was a thread about some sandy material no too long ago see what that came up with.

Well, I know you get some REAL dirty looks from the guys at the local garage when you use any thing other than wheel weights. But wheel weights are a joke unless you only street wheel it. The way to use the anti-freeze trick is to basically get them balanced. That is, find out how bad they are and how much weight they require to balance out, then weigh an equal amount of anti-freeze and dump it in! But it's sticky, spreads out on the inside.
The new deal is golf balls. I think it takes about 8-10 golf balls for a 38-39 inch tire. Should sound neat on the street at about 15-20 mph!

I heard a mixture of gravel and rusty nails works.

2 pints of elephant cum per tire, works every time ;)
