wheel weights?

Just got my tires mounted and balanced. took my rims off beforehand so the tire place would not damage them. Got home and tried to put rims back on but some of the wheel weights are in the way rim clips now. Can i pull the weights off and use adhesive backed weights more inward on the wheel and still maintain the correct balance using the same .oz weight as the ones on there now or will this screw up the balance?

As long as you replace the weights with the same size used by the shop you should be all set. The weights you stick to the rims will likely be closer to the center of the wheel than the ones you're removing but it probably won't make a noticeable difference in the balance of the wheel.

Whenever I have a nice set of rims balanced at the shop I always ask that they put the weights on the inside of the rim. Another option would be to switch the existing wheel weights from the outside of the rim to the inside. :thumbs:

Sorry to disagree, but,

I worked as a tire changer for Firestone and General Tire when I was in High School, and did a lot of tire balancing. Do not move any weight from the outside of the rim to the inside.

There are two types of balancing they do ... static and dynamic. Static balancing simply determines if the wheel has a heavy spot. All you do is rotate the wheel about 1/4 to 1/3 of a turn and release it, and see if it rotates. If it does, the wheel has a heavy spot, which will found when the wheel stops moving. The bottom is the heavy spot. Adding a single weight, usually to a the very top, will statically balance the wheel so no matter where you put the wheel, it will not rotate. Next is the dynamic balance, where they spin the wheel to highway speeds and the machine determines where and how much weight is to be added to dynamically balance the wheel.

The balancing machine tells you not only how much weight to add but also which side of the wheel to install the weights, and it does make a big difference. Moving the weight from the outside of the wheel to a point closer to the hub on the same side of the hub does not matter that much, but to relocate the weight to the inside of the wheel is not a good idea. Your best bet would be to have the wheels re-balanced with the correct weights. If you explain the problem, they may do it for free.

Interesting, I didn't realize that. Never seen wheel weights on the inside of a rim unless I asked for them to be put there so I figured it didn't matter which side of the rim they put the weights. Guess you learn something every day!
