I ordered a set of 18x10 bullits for my gt and when i opened them there were some extra wheels weights in the boxes. I had the tires mounted and balanced so i dont know if they are suppose to be on there or not, I wouldnt think they just fall off but who knows. Im goin to get them rebalanced but Ive been ridin on the dounut for like 10 days know and wanna get it off. So i wanna put them on and get them rebalanced saturday. Can I tell if they are out of balance once on the car? What if any damage can occur wit unbalanced wheels?
