I just noticed that today that on my momo's, there are little square of weight thing inside my rim, what are those for?

 

After you tires wear down a little and your suspension changes position (at a very minute degree) your wheels become out of balance. When you drive on the freeway and you see some guy's whel bouncing up and down like mad...that's the symptoms of an unbalanced wheel. Also, your tires wear unevenly. The weights are placed on the inside of the wheel to prevent that from happening. I get my wheels balanced when I start seeing uneven wear. That's usually every other year, but I get an alignment every year.

 

They are used to balance the wheel. EVERY wheel will have these weights in one form or another. Steel wheels usually have the weights clamped onto the edge of the rim. Alloy wheels get them stuck onto the wheel itself so as not to scratch the wheel.

Gotta love static balancing.

 

thanks all for the answer!

 

haha does that even exist? I like many on this forum have always liked cars. My grandpa used to get his tires from KMart and he'd get static balancing!! I remember one time he came back with tires smaller than the originals on his buick. I had a good eye for diameters even back then. He should have gotten HR78-14's but they gave him GR78-14. Then his snow tires were Jr78-14. He never had the right size so when his snows were on his car was higher in the back.

BTW I don't think spin balancing is to compensate for tire wear as a previous poster had said. The wheel is imperfect right off the bat and the balancing compensates. We're talking grams as far as how much they weigh.
