Does it make a difference. Off balance'd wheel's suck when driving, kill's wheel bearing's pretty fast too due to rototianal force. Make's the whole truck fibrate like crazy.
I'm not pretty good at balancing tire's, but i'm sure someone else is.
It would seem you need too, but I've never done it and think I'll give it a try. I just want to know what to use for balancing weights. I've heard of people taping pennies to the inside of the wheels to balance them but my set never seem that out of balance.
